The tolerance in inches for the diameter of a piston is described by the absolute value inequality d5 , or equal to 0.01. What is the desired diameter of the piston? By how much can the actual diamer of the piston vary from the desired diameter?

d5} < .01
d5 <.01 and d5>.01
d < 5.01 and d > 4.99
the desired diameter would be when d5 = 0
or
d = 5
