Equations and Expressions Homework 1

Rebecca was asked to create five pairs of like terms. Determine if she completed the task correctly by sorting her answers in to like terms or not like terms.

Groups:

(a) Like terms

,

(b) not like terms

• 38 and -15

• 5a and 5b

• 2.5w and 8w

• 1/2 x and 1/2

• 

Simplify the expression by combining like terms:

4r + 9r - 11r + 7r

Simplify the expression by combining like terms:

-r + 6 + 8r - 14

• 9r - 8

• 7r - 8

• 7r + 8

• 9r + 8

Simplify the expression by combining like terms:

-26r + 7r - 15p - 7p

• -19r - 22p

• 19r - 22p

• 33r + 8p

• -19r + 22p

Simplify the expression by combining like terms:

8r + 12p - 7 - 3p

• 8r + 9p - 7

• 9p + 1

• 20r - 10p

• 8r + 15p - 7

Simplify the expression by combining like terms:

10r - 5r + 3r -8r

Simplify the expression by combining like terms:

-4p - 2r - 15p
