Question

Mauro has 140 ft of rope. He will cut it into two pieces so that the length of the longer piece is 3 times the length of the shorter piece. What will the length of the longer piece be? _________ ft

Answer 1

140= x +3x
140 =4x
140/4= 4x/4
35= x
3x= 105
The length of the longer piece is 105 feet

Answer 2

Answer:

The length of the longer piece is 35 feet.

Step-by-step explanation:

Let the length of the longer piece is x

Hence, length of the shorter piece is 3x

Now, the length of the rope is 140 ft. Thus, we have the equation

$x+3x=140$

Add the like terms. $x+3x=4x$

$4x=140$

Divide both sides by 4

$x=35$

Therefore, the length of the longer piece is 35 feet.
