Solve using elimination
-3x + 4Y = 16
3x - y +14
Answer:
x = 8
y = 10
Step-by-step explanation:
We are given the equations;
-3x + 4Y = 16
3x - y =14
We are required to solve the two equations simultaneously using elimination
In this case, we will eliminate one unknown;
We eliminate x by adding the two equations;
That is;
-3x + 4Y = 16
3x - y =14
.............................
3y = 30
y = 10
Solving for x
3x - (10) = 14
3x = 14 +10
3x = 24
x = 8
Therefore, the solution of the equation is x=8 and y=10
The largest possible circle is cut out of a square whose side length is 8 feet. What will be the approximate area, in square feet, of the remaining board? ( A=3.14r2)
Step-by-step explanation:
Given , The length of side of the square is 8 feet.
Since a circle is inscribed in the square. Then the diameter of the circle is equal to the length of side of the square .
Therefore the diameter of the circle is = 8 feet.
Radius of the circle is(r) = [tex]\frac{8}{2}[/tex] feet = 4 feet
The area of the circle is= 3.14 r²
= 3.14 × 4² square feet
= 50.24 square feet
The area of the square is = side × side
= 8×6 square feet
=64 square feet
Therefore the area of remaining board = (64- 50.24)square feet
=13.76 square feet

Together, teammates Pedro and Ricky got 2681 base hits last season. Pedro had 283 more hits than Ricky. How many hits did each player have
Answer:
Ricky had 1199 hits.
Pedro had 1482 hits.
Step-by-step explanation:
State your variables
let "p" be the number of Pedro's base hits
let "r" be the number of Ricky's base hits
Create equations using information from the problem
p + r = 2681 [1]
p = r + 283 [2]
Substitute equation [2] in equation [1] replacing 'p'
p + r = 2681
r + 283 + r = 2681
Combine like terms to simplify
2r + 283 = 2681
Isolate '"r" to solve for Ricky's base hits.
2r + 283 - 283 = 2681 - 283 Subtract 283 on both sides
2r = 2398
2r/2 = 2398/2 Divide both sides by 2
r = 1199 Number of Ricky's hits
Substitute r = 1199 into any equation to find "p". I will use [2].
p = r + 283
p = 1199 + 283 Add
p = 1482 Number of Pedro's hits
Therefore Ricky had 1199 hits and Pedro had 1482 hits.
Ricky had 1199 hits and Pedro had 1482 hits.
Explanation:To solve this problem, we can set up a system of equations. Let x represent the number of hits Ricky had. Pedro had 283 more hits, so Pedro's number of hits would be x + 283.
Together, their hits add up to 2681, so we can write the equation:
x + (x + 283) = 2681
Combining like terms:
2x + 283 = 2681
Subtracting 283 from both sides:
2x = 2398
Dividing both sides by 2:
x = 1199
Ricky had 1199 hits and Pedro had x + 283 = 1199 + 283 = 1482 hits.
solve the system using eliminationx+7y=-37 2x-5y=21
Answer:
y = -5
x = -2
Step-by-step explanation:
x+7y=-37
2x-5y=21
Multiply first equation by -2
-2 × (x + 7y) = -37 ➡ -2x -14y = 74
now add the equation up
2x-5y -2x -14y = 21 + 74 (-2x will eliminate 2x)
-19y = 95 divide both sides by 19
y = -5 we can find the value for x by using this information
x + 7y = -37 replace y by -5
x + 7×(-5) = -37
x = -2
In a year the number of people dying from cancer was 5 times the number who died from accidents. If the number of deaths from these two causes totaled 360,000, how many people died from each cause?
Based on the number of people dying from both causes and their relationship with each other, we can calculate that the number of people dead from cancer was 300,000 and those from accidents was 60,000.
Assuming x number of people died from accidents, the number that died from cancer would be 5 times that:
= 5x
The number of people dead from accidents is:
360,000 = 5x + x
6x = 360,000
x = 60,000 people
The number dead from cancer is:
= 5x
= 5 × 60,000
= 300,000 people
In conclusion, 60,000 died from accidents and 300,000 people died from cancer.
Find out more at https://brainly.com/question/16892543.
Final answer:
To solve the problem, we created two equations: c = 5a and c + a = 360,000. After substituting and solving these equations, we found that 300,000 people died from cancer and 60,000 from accidents.
Explanation:
The question refers to a situation where the number of people dying from cancer is five times the number who died from accidents, and the total deaths from these two causes amounted to 360,000. To solve this, we can set up a system of equations. Let ‘c’ be the number of cancer deaths and ‘a’ the number of accident deaths. We are given:
c = 5a (the number of cancer deaths is five times accident deaths)c + a = 360,000 (the total number of deaths is 360,000)Substituting the first equation into the second, we get:
5a + a = 360,0006a = 360,000a = 60,000Then we substitute the value of ‘a’ back into the first equation to find ‘c’:
c = 5 * 60,000c = 300,000Therefore, 60,000 people died from accidents and 300,000 from cancer.

The bottom of Ignacio's desktop is
74.5 cm from the floor. Ignacio sits in his adjustable chair, and the tops of his legs are 49.3 cm from the floor. Each clockwise rotation of the knob on the chair raises Ignacio's legs by 4.8 cm Write an inequality to determine the number of clockwise rotations, r, Ignacio could make with the knob without his legs touching the desk.
Answer:
The inequality to determine the number of rotations is given by
r ≤ 5.25
Therefore the maximum number of rotations possible is 5.
Step-by-step explanation:
i.) The bottom of Ignacio's desktop is 74.5 cm from the floor.
ii.) The tops of his legs are 49.3 cm from the floor.
iii.) the difference between the bottom of Ignacio's desktop and the top of his legs = 74.5 - 49.3 = 25.2 cm.
iv.) Each clockwise rotation of the knob on the chair raises Ignacio's legs by 4.8 cm.
v.) let the number of clockwise rotations be r.
vi.) therefore the inequality to determine the number of rotations is given by
4.8r ≤ 25.2 therefore r ≤ 25.2/4.8 therefore r ≤ 5.25

you work it out
of 900 centimeters. The table shows the height of each bounce.
Bounce Height (cm)
1 800
2 560
3 392
The heights form a geometric sequence.
How high does the ball bounce on the 5th bounce? Round your answer to the nearest tenth of a centimeter, if necessary.
Answer:
Rounding to nearest tenth of centimeter, the ball bounces 192.1 cm high on the 5th bounce.Explanation:
The ball is dropped from a height of 900 centimeters.
Since the heights form a geometric sequence, you can find a common ratio between consecutive terms. This is:
Height bounce 2 / height bounce 1 = 560 / 800 = 0.7Height bound 3 / height bounce 2 = 392 / 560 = 0.7Hence, the ratio of the geometric sequence is 0.7, and taking bounce 1 as the start of the sequence, the general term of the sequence is:
[tex]a_n=800(0.7)^{n-1}[/tex]
With that formula you can find any term:
[tex]n=1,a_1=800(0.7)^{(1-1)}=800(0.7)^0=800\\ \\ n=2,a_{2}=800(0.7)^{(2-1)}=800(0.7)=560\\ \\n=5,a_{5}=800(0.7)^{(5-1)}=800(0.4)^4=192.08[/tex]
Rounding to nearest tenth of centimeter, the ball bounces 192.1 cm high on the 5th bounce.

10x+4y+ 12z=120
11x +77y =220
8x +2y +32z =160
Answer:
x=8.94 ; y = 1.58; z=2.02
Step-by-step explanation:
solve 10x+4y+12z = 120 → 5x+2y+6z = 60
8x + 2y +32Z = 160 → 4x+y+16z = 80
To eliminate z multiply first equation by 16 and second equation by 6.
80x+32y+96z = 960
24x+6y+96z = 480
on subtractionwe get 56x+26y = 480
dividing by 2 we get, 28x + 13y = 240
Now we have a given equation 11x + 77y = 220 → x + 7y = 20
solving 28x + 13y = 240 and x + 7y = 20
28x + 13y =240
28x + 216y = 560
subtracting we get, 203y = 320
y = 1.58
x = 8.94

If Raul Poland to run 30 miles this week but wants to run the same number of miles each day of the week what is the correct form of fraction to write this?
Answer:
Step-by-step explanation:
The correct fraction is simply 30/7, where 30 is the distance in miles and 7 is the number of days to complete it.
30/7 = 4.286miles daily but since you've asked to have this as a fraction, 30/7miles is good.
Final answer:
To achieve his goal of running 30 miles in a week, Raul should run 30 miles divided by 7 days, which is approximately 4 2/7 (⅔) miles every day.
Explanation:
If Raul wants to run 30 miles this week and he wants to run the same number of miles each day, we need to divide the total miles by the number of days in a week. There are 7 days in a week, so we will divide 30 miles by 7 days.
Using division: 30 miles ÷ 7 days = ⅔ miles per day. The fraction ⅔ represents the number of miles Raul plans to run each day to meet his goal of running 30 miles in a week.

9.5 , 9 3/4 , 9.125 , 9 3/4 from greatest to least
Answer:
9 3/4, 9 3/4, 9.5, 9.125
Step-by-step explanation:
*I converted to decimal form*
9 3/4= 9.75
9.75 is greater than both 9.5 and 9.125, so therefore it is first on the list.
Next, since 9.5 is greater than 9.125, it is arranged next on the list.
9.125 is the only number left, and is clearly the smallest out of all of the numbers shown.
We want to order the given set of numbers from greatest to lest.
The correct order is:
{9 3/4, 9 3/4, 9.5, 9.125}
Let's see how to get that.
The given set is:
{9.5, 9 3/4, 9.125, 9 3/4}
Here we can see that we have two times the mixed number (9 3/4).
This can also be written as:
9 + 3/4
And we know that 3/4 = 0.75
Then:
9 + 3/4 = 9.75
Then the mixed number is the largest number.
Then comes the 9.5, and finally the 9.125
Then the correct order is:
{9 3/4, 9 3/4, 9.5, 9.125}

Rewrite the expression in the form 4^n
(4^6)(4^-8) =
Answer:
4^-2
Step-by-step explanation:
The rules of exponents tell you ...
(a^b)(a^c) = a^(b+c)
This means ...
(4^6)(4^-8) = 4^(6-8) = 4^-2
To simplify the expression (4^6)(4^-8), add the exponents and rewrite the expression as 4^(-2). Then, use the rule that states any number raised to the power of -1 is the reciprocal of that number to rewrite 4^-2 as 1/(4^2) which equals 1/16.
Explanation:To simplify the expression (4^6)(4^-8), we can use the rule that states when you multiply two powers with the same base, you add their exponents. In this case, 4^6 multiplied by 4^-8 will be equal to 4^(6 + (-8)). Simplifying the exponent, we have 4^(-2). Since any number raised to the power of -1 is the reciprocal of that number, we can rewrite 4^-2 as 1/(4^2) which is equal to 1/16.
