Answer 2

To solve each equation, we need to isolate the variable x. We can do this by performing the inverse operation for each equation. Here are the solutions for each equation:

1. 0.21x = 6.3 Divide both sides by 0.21: x = 6.3 / 0.21 x = 30

2. 0.04x = 2 Divide both sides by 0.04: x = 2 / 0.04 x = 50

3. 2.7x = 2.727 Divide both sides by 2.7: x = 2.727 / 2.7 x = 1.009

4. 0.132x = 132 Divide both sides by 0.132: x = 132 / 0.132 x = 1000

5. 0.6x = 4.2 Divide both sides by 0.6: x = 4.2 / 0.6 x = 7

6. 17.5x = 0.63 Divide both sides by 17.5: x = 0.63 / 17.5 x = 0.036

7. 13.5x = 1.08 Divide both sides by 13.5: x = 1.08 / 13.5 x = 0.08

8. 0.34x = 10.54 Divide both sides by 0.34: x = 10.54 / 0.34 x = 31

9. 0.09x = 94.5 Divide both sides by 0.09: x = 94.5 / 0.09 x = 1050

10. 0.32x = 16.48 Divide both sides by 0.32: x = 16.48 / 0.32 x = 51.5

11. 0.35x = 2597 Divide both sides by 0.35: x = 2597 / 0.35 x = 7420

12. 1.2x = 4.02 Divide both sides by 1.2: x = 4.02 / 1.2 x = 3.35

So the solutions for the equations are:

1. x = 30
2. x = 50
3. x = 1.009
4. x = 1000
5. x = 7
6. x = 0.036
7. x = 0.08
8. x = 31
9. x = 1050
10. x = 51.5
11. x = 7420
12. x = 3.35
