Answer 1

Ответ:

×=2230

Пошаговое объяснение:

100-0.04×=10.8

-0.04×=10.8-100

-0.04×= -89.2

×=2230

Answer 2

Ответ:

х = 2230

Пошаговое объяснение:

0,8(100-0,04 х)= 8.64​

100 - 0,04х = 8,64 : 0,8

-0,04х = 10,8 - 100

-0,04х = -89,2

0,04х = 89,2

х = 2230

Проверка:

0,8(100 - 0,04 · 2230) = 8,64

0,8(100 - 89,2) = 8,64

0,8 · 10,8 = 8,64

8,64 = 8,64

Answer 3

To solve the equation 0.8(100 - 0.04x) = 8.64, you can follow these steps:

1. Distribute the 0.8 on the left side of the equation:

0.8 * 100 - 0.8 * 0.04x = 8.64

2. Simplify the equation:

80 - 0.032x = 8.64

3. Now, you want to isolate the variable x. Start by moving the constant term (80) to the other side of the equation by subtracting it from both sides:

80 - 80 - 0.032x = 8.64 - 80

-0.032x = -71.36

4. Next, divide both sides by -0.032 to solve for x:

(-0.032x) / (-0.032) = (-71.36) / (-0.032)

x = 2230

So, the solution to the equation is x = 2230.
