36. 1) 7,5x = 35,88; 4) 31 x = 353 7) x : 3,05 = 9,4; 7 10) 27 12 : x = 3,31;​

Answer 1

Ответ:

Пошаговое объяснение:

1) 7,5x = 35,88;

х=35,88:7,5

х=4,784

4) 31 x = 353

х=353:31

х=11 12/31

7) x : 3,05 = 9,4;

х=9,4*3,05

х=28,67

10) 27 12 : x = 3,31;​

х=2712:3,31  

х=271200/331

х=  819 111/331 ( тут я думаю не правильно написан сам пример. )

Answer 2

It appears you have a list of equations that involve the variable "x." You want to solve for "x" in each of these equations. Here's how you can solve each of them:

1. 7.5x = 35.88 To solve for x, divide both sides of the equation by 7.5: x = 35.88 / 7.5 x = 4.784

2. 31x = 353 To solve for x, divide both sides of the equation by 31: x = 353 / 31 x ≈ 11.3871 (rounded to 4 decimal places)

3. x / 3.05 = 9.4 To solve for x, multiply both sides of the equation by 3.05: x = 9.4 * 3.05 x ≈ 28.67 (rounded to 2 decimal places)

4. 27.12 / x = 3.31 To solve for x, multiply both sides of the equation by x: 27.12 = 3.31x Now, divide both sides by 3.31 to isolate x: x = 27.12 / 3.31 x ≈ 8.19 (rounded to 2 decimal places)

These are the solutions for each equation.
