Question 1144800
<br>
The inequality<br>
{{{abs(x-a)<=b}}}<br>
means x is a number whose distance from a is less than or equal to b.<br>
Stated differently, x is a number that is within b of a.<br>
In your problem, Carlos wants his grade to be between 75 and 85. That means he wants the grade to be within 5 points of 80.<br>
Fill in the numbers a and b so that<br>
{{{abs(x-a)<=b}}}<br>
describes the numbers that are within 5 of 80.
