Two Step Equations Combining Like Terms

The Frederick County Fair costs $15.00 to get in and $2.50 per ride, while the Montgomery County Fair costs $10.00 to get in and $3.00 per ride. Which equations could be used to determine how many rides you would need to go on for both fairs to be of equal value?

• 15x + 2.5 = 10x + 3

• 15 - 2.5x = 10 - 3x

• 15 + 2.5x = 10 + 3x

• 15 - 10 = 2.5x + 3x

Simplify the following expression:
19 - ( 3 - 5b)

• 16 + 5b

• 21 + 5b

• 16 - 5b

• 21 - 5b
