This is a test of pre-algebra and algebra skills that I wrote for a student that I tutor. Can you pass it? 1. 5 + 6 = 2. 10 – 7= 3. 3 x 5 = 4. 20 ÷ 4 = 5. 3 x 4 = 6. 2 x 6 = 7. 2 x 4 = 8. 3 x 5 = 9. 2^4 = 10. 10^4 = 11. 2 + 3 = 12. 6 – 4 = 13. 3 + 1 – 2 + 4 – 3 – 2 = 14. 3 – 3 = 15. 4 – 7 = 16. 5 x 2 = 17. -3 x 2 = 18. 6 ÷ 2 = 19. 3 ÷ 4 = 20. Round the following to the nearest tens place: a. 39 = b. 734 = c. 899 = 21. 53 x 7 = 22. 53 x 47 = 23. 860 ÷ 5 = 24. 3 inches x 3 inches = 25. 10 miles x 5 miles = 26. 140 miles ÷ 2 hours = 27. True or False: 3 x 4 ≠ 34 28. 2 + 2 ? 5 (, or =) 29. 110 ? 58 + 5 (, or =) 30. True or False: 49 ≈ 50 31. True or False: 1,024 ≈ 1,000,000 32. │- 50 + 10 │ = 33. 5 + 3 x 2 + 8 ÷ 4 = 34. 3 + 52 – 6 = 35. (1 + 15 ÷ 5) + (3 – 6) x 5 = 36. Bobo is spinning five fewer plates than Nunu. If Nunu is spinning 17 plates, then how many plates are Bobo and Nunu spinning? 37. The height of a house is half as long as its width. The width of the house is 80 feet. How tall is the house? 38. The express train is moving three times faster than the local train. If the local train is going 25 miles per hour, then what is the difference in speed between the express train and the local train? 39. Aunt Effie has $732.84 hidden in her pillowcase. Aunt Jezebel has $234.19 less than Aunt Effie has. How much money do the two women have all together? 40. Four women collected money to save the endangered Salt Creek Tiger Beetle. Keisha collected $160, Brie collected $50 more than Keisha did, Amy collected twice as much as Brie, and together Amy and Sophia collected $700. All together, how much money did the women collect? 41. On a recent payday, Travis took a shopping trip. He bought six shirts for $19.95 each and two pairs of pants for $34.60 each. He then bought a jacket that cost $37.08 less than he paid for both pairs of pants. If he paid the cashier with three $100 bills, then how much change did he receive? 42. A bat and a baseball cost a dollar and ten cents. The bat costs a dollar more than the ball. How much does the ball cost? 43. In a lake, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the lake, then how long would it take the patch to cover half of the lake? 44. 431 ÷ 1 = 45. 28 ÷ 28 = 46. 538 ÷ 2 = 47. 625 ÷ 5 = 48. 170 ÷ 10 = 49. 51 ÷ 3 = 50. 243 ÷ 9 = 51.
