Sewanhaka High School Math 8 Name:___________________________________ Per:___ Mrs. Lidowsky, Principal Mr. Long, Teacher Date:_________________ H.W. #13: Ditto DO-NOW #13: Convert each verbal sentence into an algebraic equation and solve each equation. 1) 24 is 6 more than a 2) The product of 7 and 3) Thirteen fewer than number some number is 35 some number is 3 Topic: Expressions and Equations Main Idea: Solving Two Step Algebraic Equations Aim: RECALL ( ) has seen 4 more horror movies today for a total of 10 horror movies. How many horror movies did ( ) see date the previous days? Convert the verbal sentence into an algebraic equation and solve the equation and check it. I am thinking of a number. If you double my number and add four to the result, the sum is 10. What number am I thinking of? Write an equation. What is different about the equation 4 + 2g = 10 as compared to 4 + g = 10? How would you solve and check the equation: 4 + 2g = 10? I’m thinking of a number. If you double it and add six to this product, the answer is 24. What number did I start with? How can I find the number? NOTES 4) The quotient of some number and 8 is 12 Recall How do you solve two step equations? Notes Solve and Check for m: 6m – 4 = 38 Solve and Check: 16 = c 3 5 Drill: Solve and Check: 1) 3(x – 5) = 27 2) 7 + m 3 =9 3) 9 + 3d = 45 4) Write four more than twice a number is 38 as an equation and solve. SUMMARY: If time: Mr. Shorty’s theater was $1 per carload or $.25 per person. If there were 214 carload admissions one night and the total sales was $285.50, how many individual tickets were sold?
