Question

4(1,2б+3,7)-2,8=5,2б

Answer 1

Ответ:

б=30.

Пошаговое объяснение:

4(1,2б+3,7)-2,8=5,2б

4.8б+14,8 - 2,8 = 5.2б

5.2б-4,8б=12

0,4б=12

б=$\frac{12}{0,4}$=30

Ответ: б=30.

Answer 2

Ответ:

Пошаговое объяснение:

4 * (1,2b + 3,7) - 2,8 = 5,2b

4,8b + 14,8 - 2,8 = 5,2b

4,8b - 5,2b = -14,8 + 2,8

-0,4b = -12

b = -12 : (-0,4)

b = 30

Answer 3

It looks like you've provided an equation involving a variable "б" (Cyrillic letter "be"). The equation is:

4(1,2б + 3,7) - 2,8 = 5,2б

To solve for the value of "б," let's go step by step:

1. Distribute the 4 on the left side of the equation: 4 * 1,2б + 4 * 3,7 - 2,8 = 5,2б

2. Simplify the left side: 4,8б + 14,8 - 2,8 = 5,2б

3. Combine the constants on the left side: 4,8б + 12 = 5,2б

4. Subtract 4,8б from both sides to isolate the variable "б": 12 = 0,4б

5. Now, divide both sides by 0,4 to solve for "б": б = 12 / 0,4 б = 30

So, the solution for the equation is б = 30.
