If chocolate chip cookies cost $3.00 per cookie plus $2 for boxing them up in a decorated box, what would the expression be?

• y = 3 + 2x

• y = 3x + 2

• y = 3x + 2x

• y = 5x

Which phrase matches this expression?

"The difference of a number and 12"

• x = 20
• x = 7
• x = 10
• x = 3

x+ 3=10

• 3

• 10

• 13

• 7

• x=1

• x=2

• x=11

• x=-1

• x=5

• x= -15

• x=3

• x=15

Solve for x.
10-5x+3x= 5 - x

• 5
• -2.5
• -5
• 10

-5-r = 1+2r

• 21
• - 2
• - 4
• 4

10-10x = 1-9x

• 99
• - 3
• 9
• 1
