Answer:
13) A
14) B
15) C
16) C
Step-by-step explanation:
13)
Since the total number of seats, 18,000, is a combination of both the field and the grandstand seats, their number needs to be added together. Therefore, the equation is s+7,500=18,000.
14)
If you subtract 56 from both sides of the equation that you are given, you will be left with a=72.
15)
If you divide both sides of the equation by 2.4, you will be left with p=3.15.
16)
If you divide both sides of this equation by 2/3, you will be left with w=(3/4)/(2/3)=9/8 or 1 1/8 pounds. Hope this helps!
