If Ill m, solve for x and y.
(3x - 29)
(8y + 17)
(6x - 7)
X =
y =

x=24 y=15

Step-by-step explanation:

Alternate exterior angle

6x-7=8y+17

(8y+17) + (3x-29) = 180

(3x-29) + (6x-7)= 180

combine like terms solving for x first because it's easier

9x-36=180

add 36 to both sides

9x=216

divide both sides by 9 to get x by itself

x=24

now you know what x is plug it in for your choice of equations to solve for y

6(24)-7=8y+17

144-7=8y+17

137=8y+17

subtract 17 from both sides

120=8y

divide both sides by 8

15=y

(8y+17) + (3(24)-29) = 180

8y+17+72-29=180

combine like terms

8y+60=180

subtract 60 from both sides

8y=120

divide by 8 on both sides

y=15

understand that i don't know the answers

will someone answer his question

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
