But do not forgot if they are across from eachother they equal the same thing, notice how these two angles look the exact same so the answer will be 82

X = 82

a corresponding angle of 82 is also the vertical angle to x. This makes then equal.

Resolva os sistemas abaixo 2x+3y=80 3x+2y=70 X=8y X+4y=480

timurjin [86]

Solución 1: 2(x) + 3(y) = 80
solución 2: 3(x) + 2(y) = 70

3(y) + 2(x) = 80
2(y) + 3(x) = 70

2y = -3x + 70
y = -3x÷2 + 35

2x + 3(-3x÷ 2+35) = 80
-5x÷2 = -25
-5x = -50

5x = 50
x-intercept: 10
x = 10
y = -3x÷ 2+35

y = -(3÷2)(10)+35 = 20

x-interpcet: 10
y-intercept: 20
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
solución: x - 8y = 0
solución x + 4y = 480

-8y + x = 0
4y + x = 480

x-intercept (solución 2)
x = -4x + 480

x-intercept (solución 1)
4y + 180 - 8y = 0
-12y = 480

y-intercept: 40
x-intercept: 320

What is the answer to 7 (10-3x) = 5(10-4x

astra-53 [7]

Answer: 70-27x = 50-20x

Step-by-step explanation: First you do 7 x 10 which equals 70 then 7 x -3x equals -27x. Next you do 5 x 10 which is 50 next you do 5 x -4x equals -20x. So your answer is 70-27x = 50-20x
