• x = 12

• x = 17.5

• x = 19.5

Solve for x

5 ( 2x + 3 ) = 45

• 3

• 10

• 4

• 2

• x = 106

• x = -106

• x = 16

• x = -16

Miley runs a "warm-up" lap for 10 minutes and then takes nine minutes to run each mile. The total time after running m miles is 55 minutes. Which equation models this scenario?

• 55 = 10m + 9

• 55 = 9m - 10

• 55 = 10m - 9

• 55 = 9m + 10
