Five bags of chips cost $7. 1. What is the price per bag?
2. At this rate, how much will 8 bags of chips cost?

1. $1.40 2. $8.40

Step-by-step explanation:

1. 7 divided by 5 is 1.4

2. 1.40 plus $7 equals $8.40

1 bag=$1.04

8 bags=$11.02

Step-by-step explanation:

Divide 5 by 7. You will get 1.4, which equals 1.04 in money. That times 8 equals 11.02

x = 9

Step-by-step explanation:

7x + 3x - 18 = 6(x + 3)

10x - 18 = 6(x + 3)                  Add like terms

10x - 18 = 6x + 18                   Distribute 6 to x and 3

4x - 18 = 18                             Subtract 6x to both sides

4x = 36                                  Add 18 to both sides

x = 9                                      Divide 4 to both sides
