Answer:

x=2 y=10

Step-by-step explanation:

The triangles are similar so we can use ratios to solve

15 20

----- = -------------

x+4 8

Using cross products

8*15 = 20 (x+4)

120 = 20(x+4)

Divide each side by 20

120/20 = 20(x+4)/20

6 = x+4

Subtract 4 from each side

6-4 = x+4-4

2 =x

25 20

----- = -------------

y 8

Using cross products

25*8 = 20y

200 =20y

Divide by 20

200/20 = 20y/20

10=y

-4.5-4.2(-x-5.5)=3x solve for x

Mice21 [21]

-4.5 - 4.2(-x - 5.5) = 3x
-4.5 + 4.2x + 23.1 = 3x
18.6 + 4.2x = 3x
subtract 4.2x from both sides of the equation
18.6 = -1.2x
divide -1.2 from both sides of the equation
-15.5 = x
