9. Write an algebraic expression for: the quotient of the product of two and n and m

10. 2nm2nm

11. Write a word expression for this:

12. Answers vary! Sample: The quotient of six and three multiplied by the sum of six and three

13. The FIRST step in evaluating an algebraic expression is called the _____________step

14. The FIRST step in evaluating an algebraic expression is called the substitution step

15. Evaluate when n = -3: 3n – (-7)

16. 3(-3) – (-7) (-9) + 7 -2

17. Evaluate when n = -3 and r = -2: (nr) 2

18. ((-3)(-2)) 2 (6) 2 36

19. Evaluate when n = -2 : (n – 3)(n – 4) ÷ (-3n)

20. ((-2) – 3)((-2) – 4) ÷ (-3(-2)) (– 6)(– 6) ÷ (6) (36) ÷ (6) 6

21. Evaluate when n = -4 and p = 2: (3n + 9 - np) n + 2p

22. (3(-4) + 9 - (-4)(2)) -4 + 2(2) (-12 + 9 - (-8)) 0 1 (Trick! Anything to exponent 0 is one )

23. We solve equations by using these operations

24. INVERSE operations

25. n + (-7) = 8 What do you do to solve this?

26. n + (-7) = 8 +7 +7 n = 15

27. What do you do to solve this? -4n = -12

28. -4 n = 3

29. a – (-9) = -4 What do you do to solve this?

30. a – (-9) = -4 -9 -9 a = -13

31. Tell 3 things you could do to both sides of this equation to solve it: -x = 8

32. Divide both sides by -1 OR Multiply both sides by -1 OR Add x then subtract 8 from both sides -x = 8

33. – 3 + 2j = 4 What is the “wrapping paper”?

34. – 3 + 2j = 4 The “wrapping paper” is -3. In other words, -3 is the FIRST term that you ‘cancel out’.

35. -2b – 3 = -19 Solve

36. -2b – 3 = -19 +3 +3 -2b = -16 -2 b = 8

37. -8 – 3x= -17 Solve

38. -8 – 3x= -17 +8 -3x = -9 -3 -3 x = 3

39. 1.2k – 6 = 6 Solve

40. 1.2k – 6 = 6 +6 +6 1.2k = 12 1.2 1.2 k = 10

41. 2(-3p + 6) = -18 Solve (hint: it’s 3 steps!)

42. 2(-3p + 6) = -18 2 2 -3p + 6 – 6 = -18 – 6 -3p = -24 -3 p = 8

43. In most word problems “of” means what operation?

44. In most word problems “of” means MULTIPLICATION

45. Write an equation: 4 less than twice a number n is 6

46. 2m – 4 = 6

47. Two-thirds of a number n, decreased by 3, is 12 2n/3 – 3 = 12

48. The quotient of a number n and -8, less 5, is 25 n/(-8) – 5 = 25

49. Write an equation then solve: Jim is 2 years less than twice his sister’s age. If Jim is 12 how old is his sister?

50. 2a – 2 = 12 -2 -2 2a = 12 2 a = 7
