Question

A rope 25 feet long is cut into 3 pieces. The forest piece is 2x feet long, the second piece is 5x feet long, and he third piece is 4 feet long.
a. Write and solve and equation find x.

b. Find the length of the first and second piece

Answer 1

(a) 2x + 5x + 4 = 25 <== ur equation
    7x + 4 = 25
    7x = 25 - 4
    7x = 21
     x = 21/7
    x = 3

(b) first piece = 2x....= 2(3) = 6 ft <=
     second piece = 5x....= 5(3) = 15 ft <=
