Sample Pre Algebra Questions and Answers

1. What is the value of x in the equation: x + 5 = 12?
The value of x is 7. By subtracting 5 from both sides of the equation, we find that x = 7.

2. Solve for x: 3x = 18
To find x, divide both sides of the equation by 3. This gives x = 6.

3. What is the result of the expression 2x - 4 when x = 5?
Substitute x = 5 into the expression. 2(5) - 4 = 10 - 4 = 6.

4. If y - 7 = 10, what is the value of y?
Add 7 to both sides of the equation. So, y = 17.

5. Simplify the expression: 5x + 3x
Combine the like terms. 5x + 3x = 8x.

6. Solve for x: x/4 = 3
Multiply both sides by 4. x = 12.

7. What is the perimeter of a rectangle with length 8 units and width 5 units?
The perimeter is 2(8 + 5) = 2(13) = 26 units.

8. If the area of a square is 16 square units, what is the length of one side?
The area of a square is side × side, so the length of one side is √16 = 4 units.

9. What is the sum of -4 and 6?
The sum is 2, because -4 + 6 = 2.

10. Simplify the expression: 3x + 4x - 2x
Combine the like terms. 3x + 4x - 2x = 5x.

11. Solve for x in the equation: x - 3 = 7
Add 3 to both sides. x = 10.

12. If a triangle has a base of 6 units and a height of 4 units, what is its area?
The area of a triangle is (base × height)/2, so the area is (6 × 4)/2 = 12 square units.

13. Simplify the expression: 7y - 2y
Combine like terms. 7y - 2y = 5y.

14. What is the value of 3 raised to the power of 2?
3 raised to the power of 2 is 9, because 3 × 3 = 9.

15. Solve for x: 2x + 3 = 9
Subtract 3 from both sides: 2x = 6. Now divide both sides by 2: x = 3.

16. What is the value of 5 squared?
5 squared is 25, because 5 × 5 = 25.

17. If 6 + x = 11, what is x?
Subtract 6 from both sides. x = 5.

18. Solve for x: x/3 = 4
Multiply both sides by 3. x = 12.

19. What is the solution to the equation 2x - 3 = 11?
Add 3 to both sides: 2x = 14. Now divide by 2: x = 7.

20. Simplify the expression: 5 + 2 - 3
The result is 4, because 5 + 2 = 7 and 7 - 3 = 4.

More Sample Questions and Answers

Subtract 8 from both sides. x = 7.

22. Simplify the expression: 3a + 4a
Combine the like terms. 3a + 4a = 7a.

23. What is the value of x in the equation 4x = 16?
Divide both sides by 4. x = 4.

24. What is the result of 12 divided by 4?
The result is 3, because 12 ÷ 4 = 3.

25. If the perimeter of a square is 36 units, what is the length of one side?
Divide the perimeter by 4: 36 ÷ 4 = 9 units.

26. What is the product of 5 and 7?
The product is 35, because 5 × 7 = 35.

27. Solve for y in the equation 3y - 4 = 14
Add 4 to both sides: 3y = 18. Now divide by 3: y = 6.

28. Simplify the expression: 10x - 5x
Combine the like terms. 10x - 5x = 5x.

29. What is the value of x in the equation 5x = 20?
Divide both sides by 5. x = 4.

30. If the area of a rectangle is 36 square units and the width is 4 units, what is the length?
Divide the area by the width: 36 ÷ 4 = 9 units.

31. Solve for x: 2x + 5 = 13
Subtract 5 from both sides: 2x = 8. Now divide by 2: x = 4.

32. What is the value of -8 + 3?
The result is -5, because -8 + 3 = -5.

33. What is the area of a circle with a radius of 5 units?
The area is π × r², so the area is approximately 3.14 × 5² = 78.5 square units.

34. Solve for x: 3x - 4 = 2
Add 4 to both sides: 3x = 6. Now divide by 3: x = 2.

35. What is the sum of 4, -2, and 6?
The sum is 8, because 4 - 2 + 6 = 8.

36. What is the perimeter of a rectangle with length 10 units and width 3 units?
The perimeter is 2(10 + 3) = 2(13) = 26 units.

37. If a number is multiplied by 6 and the result is 24, what is the number?
Divide 24 by 6. The number is 4.
