Answer 1

Пошаговое объяснение:

1) 0.21х = 6.3, х = 6.3 : 0.21, х = 30

4) 0.132х = 132, х = 132 : 0.132, х = 1000

7) 13.5х = 1.08, х = 1.08 : 13.5, х = 0.08

10) 0.32х = 16.48, х = 16.48 : 0.32, х = 51.5

2) 0.04х = 2, х = 2 : 0.04, х = 50

3) 2.7х = 2.727, х = 2.727 : 2.7, х = 1.01

5) 0.6х = 4.2, х = 4.2 : 0.6, х = 7

6) 17.5х = 0.63, х = 0.63 : 17.5, х = 0.036

8) 0.34х = 10.54, х = 10.54 : 0.34, х = 31

9) 0.09х = 94.5, х = 94.5 : 0.09, х = 1050

11) 0.35х = 2597, х = 2597 : 0.35, х = 7420

12) 1.2х = 4.02, х = 4.02 : 1.2, х = 3,5

Answer 2

Solving Equations:

To solve the given equations, we will isolate the variable on one side of the equation. Here are the solutions for each equation:

1) 0.21x = 6.3 To isolate x, we divide both sides of the equation by 0.21: x = 6.3 / 0.21 x = 30

4) 0.132x = 132 To isolate x, we divide both sides of the equation by 0.132: x = 132 / 0.132 x = 1000

7) 13.5 + x = 1.08 To isolate x, we subtract 13.5 from both sides of the equation: x = 1.08 - 13.5 x = -12.42

10) 0.32x = 16.48 To isolate x, we divide both sides of the equation by 0.32: x = 16.48 / 0.32 x = 51.5

-2) 0.04x = 2 To isolate x, we divide both sides of the equation by 0.04: x = 2 / 0.04 x = 50

3) 2.7x = 2.727 To isolate x, we divide both sides of the equation by 2.7: x = 2.727 / 2.7 x = 1.01

5) 0.6x = 4.2 To isolate x, we divide both sides of the equation by 0.6: x = 4.2 / 0.6 x = 7

6) 17.5x = 0.63 To isolate x, we divide both sides of the equation by 17.5: x = 0.63 / 17.5 x = 0.036

8) 0.34x = 10.54 To isolate x, we divide both sides of the equation by 0.34: x = 10.54 / 0.34 x = 31

9) 0.09x = 94.5 To isolate x, we divide both sides of the equation by 0.09: x = 94.5 / 0.09 x = 1050

11) 0.35x = 2597 To isolate x, we divide both sides of the equation by 0.35: x = 2597 / 0.35 x = 7420

12) 1.2x = 4.02 To isolate x, we divide both sides of the equation by 1.2: x = 4.02 / 1.2 x = 3.35
