5) A section of rope is divided into 4 pieces. The 1st piece is 3 times as long as the 2nd piece. The 3rd piece is as long as the 2nd piece less 25 feet. The 4th piece is 2 times as long as the 2nd piece plus 30 feet. Write an expression representing each rope piece. How long is each piece of rope if the total length is 425 feet.​

Answer 1

1= 180 ft

2 = 60 ft

3= 35 ft

4= 150 ft

Explanation:

1 = 3x

2=x

3=x-25

4= 2x+30

425= 7x -5

420=7x

x=60
