Question: 1. 3 +2 7 = 2. (3 + 2 ) 7 = 3. 3 + 22 - 1 = 4. (3 + 2)2 - 1

1. 3 +2 7 = 2. (3 + 2 ) 7 = 3. 3 + 22 - 1 = 4. (3 + 2)2 - 1 = 5. 12/4 + 2 = 6. 12/(4 + 2)2 = 7. 2 (8 - 22) - 1 = 8. 2 (8 - 2)2 = 9. 3 2 +8 - 1 6 = 10. 3 2 + (8 - 1) 6 = 11. The fraction 34 corresponds to a percentage of _________________ . 12. Express 30% as a fraction. 13. Convert 12 to a decimal. 40 14. 2+8 = 13 13 15. 5214 = 16. 15 34 = 17. 1.456 + .35 = 18. 4.25/.5 = 19. In a group of 80 students, 20% are psychology majors. How many psychology majors are in this group? 20. A company reports that two-fifths of its employees are women. If there are 90 employees, how many are women? 21.3+(-2)+(-1) +4= 22. 6 - (-2) = 23. -2 - (-4) = 24. 4 (-3) = 25. -2 (-6) = 26. -2 (-4) (-3) = 27. 12 (-3) = 28. -16 8 = 29. 43 = 30. If X = 2 and Y = 3, then XY3 = 31. If X =2 and Y = 2, then (X + Y)2 = 32. (9 + 2)2 = 33.36/ 9= 34. (-3)3 35. If a = 3 and b = -1, then a2b3 = For each equation, find the value of X. 36. X + 6 = 13 37. 3X=12 38. 24 = 2X + 2 39. (X - 5)/3 = 2 40. 17 = 4X - 11
