The ideal width of a certain conveyor belt for a manufacturing plant is 50 in. conveyor belts can vary from the ideal width by at most 7/32in. which of the following represents the acceptable widths for the conveyor belt? check all that apply.

x> =49 25/32
x< =50 7/32
49 25/32< =x< =50 7/32
x+7/32< =50
|x-50|< 7/32

The answer is:

The ideal  width of a certain conveyor belt for a manufacturing plant is 50 in.

Conveyor belts can vary from the ideal width by at most 7/32 in.

i.e. the absolute change in the width has to be less than or equal to 7/32 in. and it can't exceed more than that.

That is if it will decrease than the  the acceptable width for the conveyor belt is represented by the expression;

Also on solving it we get:

Hence, the correct choices are:
