Figure out what n equals in this equation:

2n + 4 = -26

• n = 15

• n = -15

• n = 11

• n = -11

Solve for x:

2x - 3 + 4x = 27

• x = -15

• x = 4

• x = 5

• x = 15

Seven friends bought pizza. Each friend pitched in the same amount. If the pizza came to a total of $14.49, how much did each friend pay?

• p - 7 = $14.49

• 7p = $14.49

• p + 7 = $14.49

• p/7 = $14.49

• X = 9

• X = -9

Cadin rents a bouncy house for a birthday party. It costs $30.00 plus $4.00 per hour. If he spends a total of $78.00, how many hours did he keep the bouncy house?

• 30.00h - 4.00 = 78.00

• 30.00h + 4.00 = 78.00

• 30.00 + 4.00h = 78.00

• 30.00 - 4.00h = 78.00

A group of 3 friends each have video games at their home. Then EACH friend buys 5 more video games. Now the three friends have a total of 30 video games. How many video games did each friend start with?
