1-6. 1) is a solution for Line 2 only.
13.-1) is a solution to the system
(3.1) is a solution to the system
Answers
Option c: (-6,1) is a solution for Line 2 only
Option d: (3,-1) is a solution to the system
Explanation:
Option a: (0,3) is a solution for Line 1 only
Line 1 is [tex]6 x-7 y=25[/tex]
Let us substitute the coordinate (0,3) in Line 1, we get,
[tex]\begin{array}{r}{6(0)-7(3)=25} \\{-21=25}\end{array}[/tex]
Since, both sides of the equation are not equal, the coordinate (0,3) cannot be a solution to Line 1.
Thus, Option a is not the correct answer.
Option b: (0,0) is a solution for Line 2 only.
Line 2 is [tex]2 x+9 y=-3[/tex]
Let us substitute the coordinate (0,0) in Line 2, we get,
[tex]\begin{array}{r}{2(0)+9(0)=-3} \\{0=-3}\end{array}[/tex]
Since, both sides of the equation are not equal, the coordinate (0,0) cannot be a solution to Line 2.
Thus, Option b is not the correct answer.
Option c: (-6,1) is a solution for line 2 only.
Line 2 is [tex]2 x+9 y=-3[/tex]
Let us substitute the coordinate (-6,1), in Line 2, we get,
[tex]\begin{array}{r}{2(-6)+9(1)=-3} \\{-12+9=-3} \\{-3=-3}\end{array}[/tex]
Since, both sides of the equation are equal, the coordinate (-6,1) is a solution for line 2 only.
Thus, Option c is the correct answer.
Option d: (3,-1) is a solution to the system
Let us substitute the coordinate (3,-1) in line 1 and line 2, we get,
In line 1, we have,
[tex]\begin{array}{r}{6(3)-7(-1)=25} \\{18+7=25} \\{25=25}\end{array}[/tex]
Substituting (3,-1) in line 2, we have,
[tex]\begin{array}{r}{2(3)+9(-1)=-3} \\{6-9=-3} \\{-3=-3}\end{array}[/tex]
Since, from line 1 and line 2, both sides of the equation are equal, the coordinate (3,-1) is a solution to the system.
Thus, Option d is the correct answer.
Option e: (3,1) is a solution to the system
Let us substitute the coordinate (3,1) in line 1 and line 2, we get,
In line 1, we have,
[tex]\begin{array}{r}{6(3)-7(1)=25} \\{18-7=25} \\{11=25}\end{array}[/tex]
Substituting (3,1) in line 2, we have,
[tex]\begin{array}{r}{2(3)+9(1)=-3} \\{6+9=-3} \\{15=-3}\end{array}[/tex]
Since, from line 1 and line 2, both sides of the equation are not equal, the coordinate (3,1) is a solution to the system.
Thus, Option e is not the correct answer.

How fast should the ant walk to go around the rectangle in 4 minutes?
The ant should walk__ inches per minute.
Answers
Question:
How fast should the ant walk to go around the rectangle in 4 minutes if the sides are 12 inches and 16 inches
Answer:
The ant should walk 14 inches per minute
Solution:
Given that,
Dimensions of rectangle are 12 inches and 16 inches
Find the perimeter of rectangle
Perimeter = 2(length + width)
Perimeter = 2(12 + 16)
Perimeter = 2(28) = 56
Thus perimeter of rectangle is 56 inches
Time taken = 4 minutes
We have to find the speed at which ant covers 56 inches in 4 minutes
The speed is given by formula:
[tex]speed = \frac{distance}{time}[/tex]
[tex]speed = \frac{56}{4} = 14[/tex]
Thus the ant should walk 14 inches per minute

Two supplementary angles have measures that are in the ratio of 5 to 7. Find the measure of the smaller angle
Answers
Measure of the smaller angle is 75°
Step-by-step explanation:
Step 1: Sum of supplementary angles is 180°. Given ratio of angles is 5:7.Let angles be 5x and 7x.
⇒ 5x + 7x = 180
⇒ 12x = 180
⇒ x = 15
Step 2: Calculate smaller angle which is 5x⇒5x = 5 [tex]\times[/tex] 15 = 75°
To find the measure of the smaller supplementary angle, when the ratio of the two angles is 5:7, you need to set up an equation with 5x and 7x as the angle measures. Solve this equation to find the value of 'x', and then use 'x' to calculate the measure of the smaller angle, which amounts to 75 degrees.
Explanation:In this mathematics problem, we know that two angles are supplementary if their measures add up to 180 degrees. If the ratio of the two supplementary angles is 5:7, we can set up an equation to solve for the unknowns.
Let 5x represent the measure of the smaller angle and 7x represent the measure of the larger angle. We know that the sum of these two angles should be 180 degrees, thus:
5x + 7x = 180
Combining like terms, we get:
12x = 180
Now, we can solve for 'x' by dividing both sides of the equation by 12:
x = 180 / 12, which equals 15
Now that we know the value of 'x', we can plug it back in to find the measures of the two angles. The smaller angle, which is 5x, is then:
5x = 5 * 15, which equals 75 degrees
So the measure of the smaller angle is 75 degrees.

At a holiday camp, the ratio of boys to girls is 3: 4 and the ratio of girls to adults is 5: 7
What is the ratio of children to adults at the camp?
Answers
The ratio of boys to girls (3:4) and girls to adults (5:7) leads to a combined ratio of children to adults at the holiday camp of 5:4 after aligning the ratios on the common term for girls and simplifying.
Explanation:To determine the ratio of children to adults at the holiday camp, we can use the given ratios:
Ratio of boys to girls: 3:4Ratio of girls to adults: 5:7First, express both ratios with a common term for girls to combine them accurately:
Since the ratio of girls to adults is 5:7, we can align this with the boys to girls ratio by multiplying the boys to girls ratio by 5 (the common term for girls). This gives us:
Ratio of boys to girls (multiplied by 5): 15:20Ratio of girls to adults: 20:28So, we have 15 boys and 20 girls for every 28 adults. The total number of children (boys and girls) is 15 + 20 = 35.
Therefore, the ratio of children to adults at the camp is 35:28, which simplifies to 5:4 after dividing both terms by 7.

Which of the following accurately describes the square root of 10?
1. It is rational
2. it is an integer.
3.It is a whole number.
4. It is irrational.
Answers
Answer:
4
Step-by-step explanation:
√10 is a irrational number
Final answer:
The square root of 10 is an irrational number because it is a non-terminating, non-repeating decimal that cannot be expressed as a simple fraction. It lies between the integers 3 and 4 on the number line.
Explanation:
The square root of 10 is an example of an irrational number. Unlike integers and whole numbers, which are exact and do not have an ending decimal or fraction, and unlike rational numbers which can be written as a ratio of two integers (like 1/2 or 3/4), an irrational number cannot be expressed as a simple fraction.
The square root of 10 cannot be precisely written as a fraction because it is a non-terminating, non-repeating decimal. In other words, if we were to write out the decimal form of the square root of 10, it would have an infinite number of digits after the decimal point without any repeating pattern.
For a real-world example, consider that knowing whether a number is rational or irrational can influence how we represent that number in various contexts, such as in engineering or architecture, where precision is paramount.

find the difference and the next three terms -10 -20 -30
Answers
Answer:
- 40, - 50, - 60
Step-by-step explanation:
Note the common difference d between consecutive terms of the sequence.
- 20 - (- 10) = - 20 + 10 = - 10
- 30 - (- 20) = - 30 + 20 = - 10
Thus the difference d = - 10
To obtain a term in the sequence subtract 10 from the previous term
- 30 - 10 = - 40
- 40 - 10 = - 50
- 50 - 10 = - 60
The next 3 terms are - 40, - 50, - 60

B. 52 beats/min
C. 1912 beats/min
D. 1788 beats/min
Answers
Answer:
B. 52 beats/min
Step-by-step explanation:
while resting her heart beats : 36×2 = 72 beats/min
while running her heart beats : 1 860÷15 = 124 beats/min
difference = 124-72 = 52 beats/min
:)
Answer:
B. 52 beats/min
Step-by-step explanation:
To find the answer you have to find the bpm of each time that Chandra recorded her heart rate. So when she recorded her heart rate when running, you simply divide 1850 by 15, and you should get 123.333 (repeating) I am assuming by the answers that we are rounding, so we are going to round that answer up. Next to find her heart rate while resting, you take her heart rate in 30 seconds, which is 36, and multiply it by 2, because it was her heart rate in half of the time that we are measuring it in. So when you multiply 36 by 2 you should get 72. The next step is to subtract 124 from 72. You answer is 52.

While Brendan is vacationing with his family at the cabin, they take a motorboat on the river. The motorboat travels
18 miles per hour in still water.
1. Let w represent the speed of the river current in miles per hour. Write an expression for how fast the
motorboat is able to go downstream (with the current) Write another expression for how fast the motorboat is
able to go upstream (against the current).
2. The motorboat travels 49 miles upstream in the same time it takes to travel 77 miles downstream. What is the
speed of the current w? Use the Elimination Method to solve.
Answers
Part 1: The speed of the boat traveling downstream is [tex](18+w)[/tex] miles per hr.
The speed of the boat traveling upstream is [tex](18-w)[/tex] miles per hr.
Part 2: The speed of the current is 4 miles per hour.
Explanation:
Part (1): The motorboat travels 18 miles per hour in still.
Let w represents the speed of the current.
When the boat travels downstream, the speed of the current will get added to the speed of the boat.
Thus, the expression can be written as [tex](18+w)[/tex] miles per hr
Hence, the speed of the boat traveling downstream is [tex](18+w)[/tex] miles per hr.
When the boat travels upstream, the speed of the current will get subtracted to the speed of the boat.
Thus, the expression can be written as [tex](18-w)[/tex] miles per hr.
Hence, the speed of the boat traveling upstream is [tex](18-w)[/tex] miles per hr.
Part (2): The boat travels 49 miles upstream in the same time it takes to travel 77 miles downstream.
The distance formula is given by [tex]distance $=$ speed $\times$ time[/tex]
Substituting, we have,
[tex]49=(18-w)t\\49=18t-wt[/tex] ---------------(1)
[tex]77=(18+w)t\\77=18t+wt[/tex] ---------------(2)
Solving using elimination method,
[tex]49=18 t-w t\\77=18 t+w t\\-------\\126=36t[/tex]
Dividing both sides by 36, we have,
[tex]t=3.5[/tex]
Substituting [tex]t=3.5[/tex] in [tex]$49=18 t-w t$[/tex], we get,
[tex]49=18(3.5)-w (3.5)\\[/tex]
[tex]49=63-3.5w\\[/tex]
[tex]-14=-3.5w\\[/tex]
[tex]4=w[/tex]
Thus, the speed of the current is [tex]w=4[/tex] miles per hour.
Final answer:
The expression for the speed of the motorboat downstream is (18 + w) miles per hour. The expression for the speed of the motorboat upstream is (18 - w) miles per hour. To solve for the speed of the current, a system of equations can be set up and solved using the Elimination Method.
Explanation:
1. When the motorboat is traveling downstream (with the current), the speed of the motorboat will be the sum of its speed in still water and the speed of the river current. So the expression for the speed of the motorboat downstream is: (18 + w) miles per hour.
When the motorboat is traveling upstream (against the current), the speed of the motorboat will be the difference between its speed in still water and the speed of the river current. So the expression for the speed of the motorboat upstream is: (18 - w) miles per hour.
2. To find the speed of the current, we can set up a system of equations. Let t represent the time taken for both the upstream and downstream trips. The distance traveled upstream is 49 miles and the distance traveled downstream is 77 miles. Using the formula Distance = Speed x Time, we can write the following equations:
(18 + w) * t = 77
(18 - w) * t = 49
We can solve this system of equations using the Elimination Method. First, multiply the first equation by (18 - w), and multiply the second equation by (18 + w) to eliminate the variable w:
[(18 + w) * t] * (18 - w) = [(18 - w) * t] * (18 + w)
Simplify both sides of the equation:
(18 + w)(18 - w)t = (18 - w)(18 + w)t
Expand:
(18² - w²)t = (18² - w²)t
Cancel out the like terms:
324 - w² = 324 - w²
This equation is true for any value of w. Therefore, there are infinitely many possible values for the speed of the current w. The specific value of w would depend on the given values of t and the distance.

How do u solve y=296-10x and y=200+6x
Answers
Answer:
[tex]x = 6[/tex] and [tex]y = 236[/tex]
Step-by-step explanation:
[tex]y = 296 - 10x[/tex]
[tex]y = 200 + 6x[/tex]
By equating both equations, we get:
[tex]296 - 10x = 200+6x[/tex]
[tex]16x = 96[/tex] [Separate variables and constants]
[tex]x = 6[/tex]

What are quadrilaterals?A closed quadrilateral has four sides, four vertices, and four angles. It is a form of a polygon. In order to create it, four non-collinear points are joined. Quadrilaterals always have a total internal angle of 360 degrees.
Given the quadrilateral ABCD and opposite sides are parallel,
AD ║ BC and AB ║ CD
since the opposite sides of the quadrilateral are parallel so the quadrilateral is a parallelogram,
so AB = CD
AB = x + 3 and CD = 2x - 6
x + 3 = 2x - 6
2x - x = 3 + 6
x = 9
