2. Lesson 5: More Word Problems • Learning Goals • I can create equations from word problems • I can solve equations that represent real life problems Unit 3: Solving Equations

3. Unit 3: Solving Equations Lesson 5: More Word Problems Worksheet Answers n + 11 = 48 (n = 37) n – 9 n3 = 48 n + 7 = 33 (n = 27) n – 3 = 27 (n = 30)

4. Unit 3: Solving Equations Lesson 5: More Word Problems Worksheet Answers 6. n – 18 = 19 (n = 37) 7. n(5) = 9 (n = 8. n – 9 = 32 (n = 41) 9. n2 = 11 10. n + 12 = 44 (n = 32)

5. Unit 3: Solving Equations Lesson 5: More Word Problems Worksheet Answers 11. n – 17 = 15 (n = 32) 12. (n = 13. n - 4 = 8 (n = 12) 14. n – 21 = 37 (n = 48) 15. n3 = 25
