Question

A 15​-foot board is cut into two pieces. If one piece is x feet​ long, express the other length in terms of x.

Answer 1

since you dont know the integer lengths of the pieces the length of the other piece would be 15 - x feet

Answer 2

Answer: The required expression would be,

15 - x

Explanation:

Given,

Total length of the board = 15 foot,

If it is cut into two pieces,

Such that, the length of one piece = x feet,

Therefore,

The length of other piece ( in ft ) = total length - length of one piece

= 15 - x

Which is the required expression.
