Step-by-step explanation:

5x+52=9x+20

subtract 5x on both sides

subtract 20 on both sides

32=4x

divide by 4 on both sides

x=8

plug in x to the equations for A, D, and C

A and D are 92°

C is 56°

B and C will add up to 90, so

90-56=34°

13y-6=34

add 6 on both sides

13y=40

divide by 13

y=40/13 (I don't wanna calculate that)

Terrance is making a scale model of a
Tanya [424]

Answer:

6.4 inches

Step-by-step explanation:

We are going to have to use ratio's here. We know that 1 inch = 2.5 feet and we know that Terrance is making a scale model of a  car that is 16 feet long. We need to work out the length of the car in inches so,

1 inches = 2.5 feet

? inches = 16 feet

→ We are going to divide 16 by 2.5 and then multiply that answer by 1 to get our result so

16 ÷ 2.5 = 6.4

6.4 × 1 = 6.4

The final answer is 6.4 inches
