How do u solve y=296-10x and y=200+6x
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]
By substituting [tex]x = 6[/tex] to the above equation, we get:
[tex]y = 296 - 10(6)[/tex]
[tex]y = 296 - 60[/tex]
[tex]y = 236[/tex]

Answer:
Option A. one rectangle and two triangles
Option E. one triangle and one trapezoid
Step-by-step explanation:
step 1
we know that
The area of the polygon can be decomposed into one rectangle and two triangles
see the attached figure N 1
therefore
Te area of the composite figure is equal to the area of one rectangle plus the area of two triangles
so
[tex]A=(8)(4)+2[\frac{1}{2}((8)(4)]=32+32=64\ yd^2[/tex]
step 2
we know that
The area of the polygon can be decomposed into one triangle and one trapezoid
see the attached figure N 2
therefore
Te area of the composite figure is equal to the area of one triangle plus the area of one trapezoid
so
[tex]A=\frac{1}{2}(8)(4)+\frac{1}{2}((4+8)(8)=16+48=64\ yd^2[/tex]

find the difference and the next three terms -10 -20 -30
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

13.-1) is a solution to the system
(3.1) is a solution to the system
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.

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.
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.
Marc was born on his grandmother’s 56th birthday. In how many years will Marcs grandmother be 5 times as Marc will be then?
Answer:
In 14 years Marc's grandmother will be 5 times as Marc will be then
Step-by-step explanation:
1. Information given to us to solve the problem:
Marc's age today = 0
Marc's grandmother age today = 56
2. In how many years will Marc's grandmother be 5 times as Marc will be then?
x = Number of years when Marc's grandmother age will be 5 times as Marc will be then
Let's solve for x, this way:
5 times Marc age in x years = Marc's grandmother age in x years
5 (0 + x) = 56 + x
5x = 56 + x
5x - x = 56 (Subtracting x at both sides)
4x = 56
x = 56/4
x = 14
Let's prove that x = 14 is correct:
5 (0 + 14) = 56 + 14
70 = 70
We proved that x = 14 is correct
In 14 years Marc's grandmother will be 5 times as Marc will be then

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
Hence the value of x is 9.

Two supplementary angles have measures that are in the ratio of 5 to 7. Find the measure of the smaller angle
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.
