Ruth · Answer 1

The correct answer is 82

Step-by-step explanation:

1st piece=x

2nd piece=3x+3

3rd piece=4x-8

Combine like terms:

x+3x+4x=8x

3-8 = - 5

8x-5=175

8x-5+5=175+5

8x=180

x=22.5

1st piece=22.5 in

2nd piece=70.5 in

3rd piece = 82

3rd piece is the biggest, so the correct answer is 82
