Answer:
B, C, A, B, D
Step-by-step explanation:
6. b+9=63
To do this we need to isolate b.
We can do this by subtracting 9 from both sides.
b=54
Choice B.
7. There are 2000 pounds in a ton.
This means that this can be modeled with a multiplication expression.
2.5*2000=5000
Choice C.
8. Since he wants to divide it equally amongst 5 groups, we need to do total/number of groups.
This situation can be modeled by 1320/5=264
Choice A.
9. Dexter makes 12.50 each hour for 4.5 hours. This can be modeled by multiplication.
12.5*4.5=56.25
Choice B.
10. First we need to find the total number of photos. 23+16+18+21+32=110
Now we divide the total number by number of groups.
110/5=22
Choice D.
