Answer:
23.
Step-by-step explanation:
You would multiply the 4 sizes of carpet by the 3 qualities, which equals 12. Then, you add 5+2+2+2. So it would end up being 12+11.
<u> All real numbers</u> is the answer
We can write this expression as 10 - 4 = 9 - x
10 - 4 = 9 - x
6 = 9 - x
6 - 9 = 9 - x - 9
-3 = -x
-3/-1 = -x/-1
3 = x
