Question

Handrail should be mounted 34 inches minimum and 38 inches maximum above ramps. Which inequality represents the required height?

Answer 1

`34 \leq x \leq 38`

Explanation:

34 inches minimum

This means that x has to be at least 34, that is:

`x \geq 34`

38 inches maximum

This means that x can be at most 38, that is:

`x \leq 38`

Which inequality represents the required height?

The intersection of 34 minimum and 38 maximum is:

`34 \leq x \leq 38`
