Algebra Quick Test

June 2011

Put the numbers one to 12down the page

This is a speed test.We will then go through it together.

1. Simplify by collectinglike termsa + a + 3a

= 5a

2. Simplify by collectinglike terms

ab + ab+ 3ab = 5ab

3. Simplify by collectinglike terms

4ab + 2a+ 3a = 4ab + 5a

4. Simplify by collectinglike terms

a2 + a2+ 3a2 = 1a2 + 1a2+ 3a2

= (1+1+3)a2

= 5a2

5. Solve 3x = 10

x = 10/3x = 3 1/3

or x = 3.3333333or x = 3.3 recurring

6. Solve a2 = 9

a.a = 9a = 3

because 3x3=9

7. Solve 3x = 12

x = 12/3

x = 4

8. Solve 3x = 2x + 6

3x – 2x = 6x = 6

9. Solve 3x – 6 = 2x + 6

3x – 2x = 6 + 6x = 12

10. Solve 3x + 3 = 2x + 6

3x – 2x = 6 - 3x = 3

11. Solve 3x = 4x – 6

3x – 4x = -6-x = -6x = 6

12. Solve 3x = 2x + 9

3x – 2x = 9x = 9
