Help With my Math Problem

[From: ] [author: ] [Date: 12-12-08] [Hit: ]
With an explanation too so that hopefully I can do the rest of these problems without needing to ask on Yahoo Answers-you had 21≤x≤29 which is correct.you have given the solution to the absolute value inequality theyre asking for,this equation in words is, the distance that x is from 25 is ≤ 4.......
Okay, so for math we have this problem, and I honestly do not know what to do - help would be very much appreciated!

"Your car averages 25 miles per gallon. The actual mileage for city driving varies from the average by 4 miles per gallon, depending on the traffic conditions. Write an absolute value inequality that shows the range for mileage that your car gets in the city."

So I was thinking that it'd be like x is greater than or equal to 21, and less than or equal to 29, but that's not an inequality... please help? With an explanation too so that hopefully I can do the rest of these problems without needing to ask on Yahoo Answers

you had 21≤x≤29 which is correct. you have given the solution to the absolute value inequality they're asking for, which is:

|x - 25| ≤ 4

this equation in words is, "the distance that x is from 25 is ≤ 4."
