2 WRITING AND SOLVING EQUATIONS

3 Objective  TLWBAT simplify expressions, solve equations, and construct expressions and equations from number sentences by combining like terms and using inverse operations to successfully complete 8 out of 10 practice problems.  NJCCCS 4.3.7.C.2, 4.3.7.D.2, 4.3.7.D.3  Common Core 7.EE.A.1, 7.EE.B.3, 7.EE.B.4a

4 Write an equation and solve: A number increased by 4 is 13.

5 Write an equation and solve: Six less than a number is 7.

6 Write an equation and solve: Two times a number is 26.

7 Write an equation and solve: A number divided by 3 is 8.

8 Write an equation and solve: Four more than two times a number is 16.

9 Write an equation and solve: Kristie’s sister is four years older than Kristie. If Kristie’s sister is 26, how old is Kristie?

10 Write an equation and solve: Jack bought a pair of jeans and a t-shirt. He spent $48 on the pair of jeans. If he spent $66 in all, how much did he spend on the t-shirt?

11 Write an equation and solve: Jack bought a pair of jeans and a t-shirt. He spent $48 on the pair of jeans. If he spent $66 in all, how much did he spend on the t-shirt?

12 Write an equation and solve: Lyanne paid $36 for four boxes of cereal. If each box of cereal cost the same amount, how much did one box of cereal cost?

13 Write an equation and solve: Joey and Trista rented a boat. The rental charge was $15 per hour. If they paid $45 for the boat rental, how long did they use the boat?

14 Write an equation and solve: Taryn hired a DJ for her birthday party. The DJ charged an initial one-time fee of $50 plus $25 per hour. If Taryn paid the DJ $150, how long did the DJ work at her party?

15 Classwork  Complete the One-Step Equations Word Problems Handout

16 Exit Ticket  Carlos is trying to read 12 pages of his book a night. The book has 156 pages. How many days will it take him to finish the book?
