Rope Length = 1st Piece + 2nd Piece

Where 1st Piece = 1/2 the 2nd Piece.

Therefore.

Rope Length = 1/2x + x

Now substitute and solve for x.

66 = 1/2x + x

66 = 3/2x

/1.5 / 1.5

44 = x

Therefore the longer piece is 44.

Proof.

First Piece: 1/2 x = 44 / 2 = 22

Second Piece = x = 44

22 + 44 = 66

Gabriela · Answer 2

Assume the longer piece is x feet long,

Then the other piece is 0.5x feet long

In total: x + 0.5x = 66 - > x = 44

So the longer piece is 44 feet, shorter piece is 22 feet
