Greg has a piece of rope that is 18 ft long. he wants to cut it into two pieces so that the longer piece is 2 ft less than 3 times the length of the shorter piece. how long will each piece of rope be? enter your answers in the boxes.

Answer : The length of the shorter and longer piece of the rope is, 5 ft and 13 ft respectively.

Step-by-step explanation :

Let the length of the shorter piece of rope be, 'x' ft.

Given:

Total length of the rope = 18 ft

Length of the longer piece = (18 - x) ft

and,

The longer piece is 2 ft less than 3 times the length of the shorter piece. That means,

Thus, the length of the shorter piece of rope = x = 5 ft

The length of the longer piece of rope = (18 - x) ft = 18 - 5 = 13 ft

Hence, the length of the shorter and longer piece of the rope is, 5 ft and 13 ft respectively.
