Math Unit 6 Expressions Test

Factor out the GCF: 10x + 15

• 100x + 150

• 10(x + 5)

• 1(10x + 15)

• 5(2x + 3)

Find an equivalent expression for the given expression: 36x + 24

• 4(9x + 7)

• 4(9x + 8)

• 2(18x + 24)

• 12(3x + 2)

In which equation does x = 1

• 4x + 6x - 7 = 3

• 7-10x = 3

• 10x - 10 = 10

• 10x + 10 = 10

Find the matching expression for the following situation: Rachel and her friends want to go to the fair. It will cost $15 to park and $12 per person (p) to get in. They want to know how much money to bring with them to cover these costs.

• 15+12p

• 27p

• 15p+12p

• 15-12p

What is the value of x in the diagram?

• 8

• 3

• 2

• 18

Translate the following sentence into an inequality
four more than a number is less than 17

• x + 4 > 17

• x + 4 ≤ 17

• x + 4 < 17

• x < 17 + 4

Simplify: x + 3x + 6x + x

• 9x

• 11x

• 2x + 9x

• Can't be simplified

Solve: 6f + 4f - f = 700 + 20

What is the difference between an algebraic expression and an equation?

• Algebraic expressions do not have variables, but equations do have variables

• Expressions and equations are not different

• Expressions do not have an equal sign and equations need to have an equal sign

• Expressions need to have an equal sign and equations do not have an equal sign

Solve: 11 = x - 7
