3. Lesson 3.7 Translating and Solving Equations

4. Let’s review solving equations… In order to translate and SOLVE equations here are 5 simple steps to follow: Step 1: What is the problem asking? Step 2: What information is given? Step 3: What operation are you going to need to use to solve the problem? Step 4: Write the equation and solve (be sure to label!) Step 5: Check your answer!

5. Practice Makes Perfect! Translate and Solve the following problems: 1. Piglet has 8 acorns. When he went to visit Tigger, he gave him some acorns. He now has 3 acorns. How many acorns did he give Tigger? x = # of acorns Piglet gave to Tigger  8 – x = 3 x = 5 acorns 2. 269 students went on a math field trip. Eight buses were filled and 21 students traveled in cars. How many students were on each bus. x = Students on the bus  8x + 21 = 269 x = 31 students

6. Just a couple more… Translate and Solve the following problems: 3. A telemarketer earns $150 a week plus $2 for each call that results in a sale. Last week he earned a total of $204. How many calls resulted in sales? x = # of calls  150 + 2x = 204 x = 27 calls 4. If Ms. Palomaa’s age is increased by 6 years and that sum is multiplied by 2, the result is 122. Find Ms. Palomaa’s age. a = Ms. Palomaa’s age  2(a+6) = 122 a = 55 years old
