Representing Algebraic Equations

Thomas got a speeding ticket. The officer said he had to pay $10 for each mile(m) per hour he was going over the speed limit plus $115 in court cost. Which equation models the total cost of Thomas' fine?

• c = 125m

• c = 10m + 115

• c = 115m + 10

• c = 10m - 115

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

While at the music store, Drew bought 5 CDs(c), all at the same price. The tax on his purchase was $6, and the total was $61. Which equation models this scenario?

• c + 5 + 6 = 61

• c/5 + 6 = 61

• 5/c + 6 = 61

• 5c + 6 = 61

Solve  5x + 7 = -13

• x=4

• x=-4

• x=5

• x=-5

Solve for x

5 ( 2x + 3 ) = 45

• 3

• 10

• 4

• 2

• x = 106

• x = -106

• x = 16

• x = -16

Solve the equation:
3x - x + 2 = 4(2x - 1)

• All real numbers

• x = 1

• x = -1

• No real solution

• x = 24

• x = 12

• x = 17.5

• x = 21

• no solution

• x = 8

• x = -5

• x = 7

4(2k + 7) = 92

• k = -6

• k = 1

• No Solution

• k = 8
