Question 452624
ball bearings are used to connect moving parts and minimize friction. ball bearings for an automobile will work properly only if their diameter is within 0.01 inch, inclusive, of 5 inches. write and solve an inequality to represent the range of acceptable diameters for these ball bearings 
-----
5-0.01 < diam < 5+0.01
4.99 < diam < 5.01

OR
---
|diam-5|< 0.01 inches
