Question

A 135 foot cable is cut into two pieces, one which is 7 feet longer than the other. What is the length of the longer piece?

Answer 1

\[x+x+7=135\]
\[2x+7=135\]
\[2x=128\]
\[x=64\]

Answer 2

shorter one is 64, longer is 71

Answer 3

how is the longer one 71?

Answer 4

If we let x represent the shorter piece of rope,
then the longer piece of rope is x+7.

Answer 5

because i solved for the short one and it was 64. the long one is 7 feet longer than 64 so it must be 71

Answer 6

you can check that this is right. 71 is 7 more than 64 and 64+71=135

Answer 7

By adding those two pieces we will have the whole cable or 135 feet.
So the starting equation was x + (x+7) = 135.

Answer 8

thanks :)

Answer 9

so, longer cable is of 21 feet
and shorter = 14 feet
