Answer 2

To solve these equations, you need to isolate the variable x in each equation. Here's how you can do it for each of them:

4. x * (1/4) = 45 To isolate x, multiply both sides of the equation by the reciprocal of (1/4), which is 4. x * (1/4) * 4 = 45 * 4 x * 1 = 180 x = 180

5. x * (7/13) = 1 To isolate x, multiply both sides of the equation by the reciprocal of (7/13), which is 13/7. x * (7/13) * (13/7) = 1 * (13/7) x * 1 = 13/7 x = 13/7

6. x * (2/18) = 18 To isolate x, multiply both sides of the equation by the reciprocal of (2/18), which is 18/2 or 9. x * (2/18) * 9 = 18 * 9 x * 1 = 162 x = 162

7. x * 10 = 1/25 To isolate x, divide both sides of the equation by 10. (x * 10) / 10 = (1/25) / 10 x = (1/25) / 10 x = 1/250

8. x * (3/10) = 2 To isolate x, multiply both sides of the equation by the reciprocal of (3/10), which is 10/3. x * (3/10) * (10/3) = 2 * (10/3) x * 1 = 20/3 x = 20/3

So, the solutions to the equations are: 4) x = 180

5. x = 13/7
6. x = 162
7. x = 1/250
8. x = 20/3
