Translating Expressions Equations and Inequalities

Choose the equivalent expression.

15 + 4(5y + 10)

• 5y + 25

• 20y - 25

• 20y + 40

• 20y + 55

Which expression is equivalent to 6(3y - 2y + 7)?

• 18y + 7
• 21y - 14y + 7
• 18y + 42
• 6y + 42

Which of the following is NOT equivalent to 42x + 24?

• 2(21x + 12)

• 3(14x + 8)

• 6(7x + 4)

• 7(6x + 17)

(6x + 3y + 4) – (x + y – 5)

• 5x + 2y + 9
• 7x + 2y + 9
• 7x + 4y + 9
• 5x + 2y -1

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides
• Subtract 11 from both sides
• Add 11 to both sides
• Divide 3 on both sides.

x - 8 = -5 

• 13
• -13
• 3
• -3

-3x + 5 = -13

• x = -5

• x = 2

• x = -6

• x = 6

0 = 8z + 8 

• -1
• 1
• 0
• 8

7 + ^a⁄₃ = 5

• a= -2
• a= -6
• a= 3
• a= 15

3 + (¹∕₄)a = 31

• a= 28
• a= 112
• a= 7
• a= 67
