Answer:
Step-by-step explanation
there are 80 boxes in total
13 is the answer. You would first list the numbers from least to greatest. Then you would find which number is in the middle. But since it would be between 12 and 14, since there is no even middle, you would find the middle of 12 and 14. And 13 is between 12 and 14. Sooooooo....

Answer: x > 2</h3>
Work Shown:
5x - 14x < - 18
-9x < - 18
x > -18/(-9)
x > 2
The inequality sign flips when dividing both sides by a negative number.
Here's another approach you could take.
5x - 14x < - 18
-9x < -18
0 < -18+9x
18 < 9x
9x > 18
x > 18/9
x > 2
It's a slightly longer pathway, but it avoids a sign flip when you divide both sides by the positive number 9.
The sign flip happens two steps earlier when going from 18 < 9x to 9x > 18. In other words, A < B is the same as B > A.
