1. Unit 3 Review Please fold a paper into 6 squares. Using the front and back, number your paper from 1-12. 1.2. 3.4. 5.6.

2. 1. Write the following number as a product of the same factor. (⅞) 5

3. 2. Find the value of the expression. 7 + [4 (5 2 – 5) – (2 3 + 2)]

4. 3. Evaluate the expression if x = 5, y = ½, and z = 2 3x – 4y 3z 2 + 18 (X 3 – 10y) ÷ z

5. 4. Write an algebraic expression to represent the following situation. One – third the amount of flour

6. 5. Write an algebraic expression to represent the following situation. Three inches more than twice the length

7. 6. Write an algebraic expression to represent the following situation. Solve using the given value of the variable. Henry has $49.00 in his bank account. He deposits $6.75 a week. What will his account balance be after x weeks? (x = 15) 1 – Write an algebraic expression 2 – Solve

8. 7. Use the distributive property to rewrite each expression. 6 (5y – 2.7) 4 (7x + 6y)

9. 8. Factor (undistribute) each expression 14x + 12 26y – 39x

10. 9. Simplify the expressions by combining like terms. 3x – x + 7x 6(8x – 3x) 13x + 8y – 7x - y

11. 10. Write two equivalent algebraic expressions to represent the situation. Make sure you identify the variable and check to make sure the expressions are equivalent. Christina and Holly rescued 6 animals as part of their Road Trip Home service learning project. Each animal they rescued will be x dollars to feed and $42.00 to vet (cost to take the pet to the doctor). Write two equivalent expressions that represent the total cost to care for the animals Christina and Holly rescued. Explain and show how the expressions are equivalent.
