Question

Rob can lift less than 135 pounds at the weight room. There is already 48 pounds of weights on the bar. Write an inequality that shows the additional weight that Rob can add, w, without being over his maximum.

Answer 1

`x + 46 < 135`

Explanation:

Given

`Initial\ Weight = 48lb`

He can lift less than 135 implies that, his maximum is:

`Total < 135`

Required

Determine the additional weight

Let the additional weight be x

Such that

`Total = x + Initial\ Weight`

`Total = x + 46`

Substitute x + 46 for Total in
`Total < 135`

`x + 46 < 135`

Hence, the inequality that describes the scenario is:
`x + 46 < 135`
