  1. 2nd 9 weeks test Review

  2. 1. Order from least to greatest • 5 squared = 25 • 8 = 8  • 2 to the sixth = 64 • 6 squared = 36 • 7 to the first = 7 • So… 7, 8, 25, 36, 64 • 7 , 8, 5 , 6 , 2 B 2 6 1 2

  3. 2. Substitute and Solve 12 9z y = 6 and z = 3 + y 12 9(3) + 6 27 = 29 2 + D

  4. 3. Jason’s SavingsStarts with $40 Each month there is an increase of $20 C Total = 40 start + 20 each month -> y = 20x + 40

  5. 4. Like Terms Same LETTER Same EXPONENT 4 4 6 4 B 11

  6. 5.Perimeter- add up all sides • 2a + x + 2a + y sides • ( 2a+ 2a )+ x + y reorder like terms • 4a + x + y combine like terms x A 2a 2a y

  7. 6. PEMDAS 2 • [ ( 1 + 4 x 3 ) – 5 ] • [ ( 1 + 4 x 3 ) – 5 ] • [ ( 1 + 12 ) – 5 ] • [ ( 1 + 12) – 5 ] • [ ( 13 ) – 5 ] • [ ( 13 ) – 5 ] • [8] • 64 2 2 2 D 2 2 2

  8. 7. Writing Expressions • Songs 3 dollars each for 15 = $ 45 • Books 9 dollars each for 3 = $ 27 • Tax = $ 7 Totaling • $ 45 + $ 27 + $ 7 = $ 79 • Expression 3 x 15 + 9 x 3 + 7 = 79 D

  9. 8. Verbal phrases to numerical expressions • 78 days to create 1 motorcycle Expression= 78n

  10. 9. 469 = 35 x + 294 Important Parts • Total to repair car= 469 • Labor = 35 per hour • Parts= 294 Overall Totals • Total = Labor + Parts • Total = 35 x + 294 • 469 = 35x + 294 c

  11. 10. q – 9 = 15 • q – 9 = 15 q = 24 Check 24 – 9 = 15 +9 +9 c

  12. 11. 9s = 36 • 9s = 36 s = 4 Check 9 (4) = 36 9 9 D

  13. 12.The opposite of 4 • - 4 !!! a

  14. 13. 3, -7, 7, -9, 6, 0 -9, -7, 0, 3, 6, 7 c

  15. 14.Absolute value of 6 • 6!!!!! A

  16. 15. 2, -3, -8, 8 • Lowest number = -8 -8 was the score for Mr. Williams D

  17. 16. -37 + (-25) Same signs add and keep -62 D

  18. 17. Evaluate a + b • a = -46 and b = 34 • a + b • -46 + 34 • Different signs Subtract. Take the sign of the larger number • -12 • A

  19. 18. 6 – 9 6 - 9 • Keep Flip Change 6 + (-9) Different signs Subtract. Take the sign of the larger # -3 C

  20. 19. p – q p = -13 and q = -50 -13 – (-50) Keep Flip Change -13 + +50 Different signs subtract. Take the sign of the larger # 37 A

  21. 20.Differnce= subtract • 100 – (-1) • Keep Flip Change • 100 + +1 = 101 B

  22. 21. 2 (-9) • 2 x 9 = 18 • Pos x Neg = Negative • -18 D

  23. 22.Multiplication • Down -15 per minute • 48 minutes • -15 x 48 • Neg x Pos = Negative • = - 720 A

  24. 23. Miguel • Spends - Negative 35 a day for 4 days = - 140 • Earns - Positive 21 a day for 5 days = + 105 -140 + 105 = - 35 B

  25. 24. h – (-22) = 11 • h – (-22) = 11 Keep Flip Change • h + 22 = 11 h = -11 D Check h – (-22) = 11 -11 – (-22) -11 + 22 = 11 -22 -22

  26. 25. f = -9 2 f = -9 Check f/2=-9 -18/2 = -9 (2) (2) 2 f = -18

  27. 26. Range = highest – lowest Range = highest – lowest 23 = highest – 37 23 = h – 37 +37 + 37 60 = h a

  28. 27. Simplify • 21 ÷ 3 = 7 24 ÷ 3 = 8 D

  29. 28. Divide Bottom into top • 12 ) 2200 1. 833 1.833= 1.83 B 12 100 96 40 36 40 36

  30. 29. Cross Multiply 18 20 32 < a 6 10

  31. 30. Compare • 0.22 • 0.79 < a

  32. 31.Order from least to greatest -0.985 -> -8 -0.950 -> -5 0.75 -0.985, -0.95, ¾ D

  33. 32. -4 means a loss of 4 A

  34. 33. Function y= total x=Car Total = salary + 300 times each car sold y = 2200 + 300x B or D

  35. 34. Two step equation d 3 +5 = 26 -5 -5 d 3 (3) (3) = 21 d = 63 D

  36. 35. Two step 2p + 9 = 27 -9 -9 2p = 18 2 2 p = 9 D

  37. 36. multi step Equation 5 h + 15 – 3 h = 32 5 h – 3 h + 15 = 32 Reorder like terms 2 h + 15 = 32 Combine like terms 2 h + 15 = 32 Solve for the variable -15 -15 2h = 17 2 2 h = 8 ½ C

  38. Any Questions? ????
