Прости за почерк я торопился

Answer 2

105 - 100%

21 - х%

Это пропорция.

Решение:

$\frac{100}{21}$ = $\frac{100}{х}$

$\frac{105 * 21}{100}$ = 22,05

Answer 3

To solve the expression, we need to find the value of the variable "Х" in the equation:

105 - 100% = 21 - Х%

First, let's simplify the left side of the equation:

105 - 100% = 105 - 100/100 = 105 - 1 = 104

Now, the equation becomes:

104 = 21 - Х%

To find the value of "Х," we need to isolate it on one side of the equation. Let's do that step by step:

1. Move 21 to the other side of the equation by subtracting it from both sides:

104 - 21 = 21 - Х% - 21 83 = - Х%

2. Now, divide both sides by -1 to solve for "Х":

Х% = -83

3. Finally, divide both sides by 100 to get the value of "Х":

Х = -83 / 100 Х = -0.83

So, the value of "Х" is -0.83 or -83%.
