Question

The ideal diameter of a gear for a certain type of clock is
12.24 mm. An actual diameter can vary by 0.06 mm. Find the range of
acceptable diameters use less than, greater than, "less than or equal to", and "greater than or equal to" to solve. Show all work. Thanks.

Answer 1

12.24 mm - 0.06 mm ≤ x ≤ 12.24 + 0.06

12.18 mm ≤ x ≤ 12.3 mm
