Mathematical Equivalence

ON

Drag and drop each set of expressions based on their equivalency.

Groups:

(a) Equivalent

,

(b) Not Equivalent

• 10f – 10 and 2(8f – 5)

• 12g + 21 and 3(4g + 7)  

• 6(4j – 6) and 24 – 36j

• 4(5c + 3)  and 9c + 7

Write an expression equivalent to 12c + 4

Mr. Parker wants to rent a cargo van for a day. It will cost the daily fee of $75 plus $0.45 per mile driven.

Let m = the number of miles Mr. Parker drives for the day. Choose the expression that shows the amount he will pay for the van. 

• 75m + 0.45

• 0.45 + m + 75

• m(0.45 + 75)

• 75 + 0.45m

Evaluate 75+0.45m

m=80
