Simplify this expression:

-3 (2 + 4x)

• 6 - 12x

• -6 + 12x

• 6 + 12x

• -6 - 12x

• 18, 21g, 24

• -5x, -5y, -5xy

• 15x, -x, 33x

• 17y, y, 17

Simplify:

32x + 8 –34x

• 6x

• -2x + 8

• 74x

• 66x + 8

Solve:

6 (x –5) = 18

• x = 2

• x = 8

• x = 4

• x = 6

Solve:

-5 (4x –2) = -30

• x = -1

• x = 8

• x = -0.6

• x = 1.4

What is the cost of a donut if a cup of coffee costs $3.25 and the total order for 3 friends was $21.75, with each ordering a cup of coffee and two donuts?

A fifteen passenger van is rented for a family vacation. The van rental is $75.00 per day, plus a $160.00 insurance fee. Which equation could be used to find x, which is the number of days the van could be rented, if they want to spend exactly $760.00 on the van rental?

• 75.00 + 160.00x = 760.00

• 75.00x - 160.00 = 760.00

• 75.00 - 160.00x = 760.00

• 75.00x + 160.00 = 760.00
