To play on the football team, a seventh grader must weigh no more than 110 pounds. your neighbor is in seventh grade and weighs 94 pounds. Write and solve an inequality that represents how much weight your neighbor can gain and still meet the requirement. (: Please help, I'm in Middle School..



Answer :

Let x represent the number of pounds the neighbor can gain and still be able to meet the requirement
No more than is the same as less than or equal to, which is represented by the 
sign.
So the inequality will be:
94 + x ≤ 110
To solve :
94 + x ≤ 110
-94         -94
--------------
x     ≤  16
Check (you should always do this, even if the problem doesn't say so)
x = 0             pick a number that should satisfy the inequality
                     because 0 is a special number (nothing) AND it is very easy to use                          AND it is very easy to plug in, it is an ideal number for check
                     (0 and 1 are the easiest numbers)
94 + 0 ≤ 110
94      ≤  110 √  <-- that's a check sign, NOT square root

Your neighbor can gain no more than 16 pounds to still be able to meet the football team requirement
