Solve and graph one-variable absolute-value equations and inequalities; interpret solutions in context.
Interpret an absolute-value statement in context
Problem
For room temperature \(|T-72|\le~3\), identify target, allowed-distance relation, solution interval, and unit.
Big Picture
What this problem is really about
In context, the expression inside absolute value compares an actual measurement with its target, and the bars turn that difference into distance. We’ll identify the center, read the comparison as a limit on allowable distance, and move that tolerance equally below and above the target. The comparison’s equality bar determines endpoint inclusion, while the contextual unit must stay attached to the resulting interval.
