Answer:

5. $1.50 6. 2 months 7. x=11; subtraction/division properties of equality

Explanation:

5. Divide 22.50/15 to find the unit price of the pepsi, or $1.50 a can

6. 24+6x=16+10x

get the variables on one side

24=16+4x

get the real numbers on one side

8=4x

divide by 4 to get x on its own

x=2. so 2 months

7. 1/2x+9=20

subtract 9 from both sides

1/2x = 11

divide each by 1/2 to get x on its own, and x=22 since 11 divided by one half is the same as multiplying it by two.
