Form K

Do you know HOW?

Solve each equation. Check your answer.

1. [pic] 2. 8x – 12 = 4x + 24 3. [pic]

4. What is the solution of [pic]? Justify your steps.

Solve each equation. If the equation is an identity, write identity. If it has no real-number solution, write no solution.

5. 2.6(t + 2) = 2(1.3t + 2) + 1.2 6. 2x + 4 = 5(x + 1) – 3(x + 2)

7. Solve [pic].

8. A large cheese pizza costs $7.50. Each additional topping for the pizza costs $1.35. If the total bill for the pizza Sally ordered was $12.90, how many toppings did she order? Define a variable and write an equation for each situation. Then solve.

9. The length of a rectangle is twice the width. An equation that models the perimeter of the rectangle is 2w + 4w = 36 where w is the width of the rectangle in ft. What are the length and the width of the rectangle?
