Answer 1

Пошаговое объяснение:

1) 9х=92,25

Х=92,25:9

Х=10,25

Проверка :

9×10,25=92,25

92,25=92,25

2) 8х=10,032

Х=10,032:8

Х=1,254

Проверка :

8×1,254=10,032

10,032=10,032

3) 13,52:х=13

Х=13,52:13

Х=1,04

Проверка :

13,52:1,04=13

13=13

4) 217,1:х=100

Х=217,1:100

Х=2,171

Проверка :

217,1:2,171=100

100=100

Answer 2

1. 9x = 92.25

To solve for x, divide both sides of the equation by 9:

x = 92.25 / 9 x ≈ 10.25

2. 8x = 10.032

To solve for x, divide both sides of the equation by 8:

x = 10.032 / 8 x ≈ 1.254

3. 13.52 / x = 13

To solve for x, multiply both sides of the equation by x:

13.52 = 13x

Now, divide both sides by 13 to isolate x:

x = 13.52 / 13 x ≈ 1.04

4. 217.1 / x = 100

To solve for x, multiply both sides of the equation by x:

217.1 = 100x

Now, divide both sides by 100 to isolate x:

x = 217.1 / 100 x ≈ 2.171
