The answer is 18 dollars. If you subtract the $7 he earned, not originally part of his allowance, you get 9. Multiply by 2 because he spent half on the movies and you get 18.

Hi I really need help with this question. SHOW YOUR WORK IF YOU ARE WILLING TO HELP ME TY! <3
Ulleksa [173]

Answer:

8.9

Step-by-step explanation:

Parenthesis are always first so,

4.5+7.6=12.1

so the problem would look like this now:

12.1-8/2.5

so convert 8/2.5 to 8÷1/5÷2 so this will become 16/5

16.5 concerted to decimal=3.2

so 12.1-3.2=8.9

serg [7]
|x| + 9 ≤ <span>7
</span>
Add -9 from each side
<span><span>|x| + 9 </span>+ <span>−9 </span></span>≤ <span>7 + <span>−9
</span></span><span>|x| </span>≤ <span>−<span>2
</span></span>
Now solve the absolute value
(You can't because the absolute value would end up less than 0 and it's not possible for that to happen)
