Answer 1

Ответ:

в первом будет 5.0

во втором будет 20.0

в третьем 2.0

Answer 2

Equation 1: |x - 5| = 0

To solve the equation |x - 5| = 0, we need to find the values of x that satisfy the equation.

The absolute value of a number is always non-negative, so for |x - 5| to equal 0, the expression inside the absolute value bars must be equal to 0.

Therefore, we have:

x - 5 = 0

Solving for x, we add 5 to both sides of the equation:

x = 5

So the solution to the equation |x - 5| = 0 is x = 5.

Equation 2: 2 - x = 0

To solve the equation 2 - x = 0, we need to isolate x.

Subtracting 2 from both sides of the equation, we have:

-x = -2

Multiplying both sides of the equation by -1 to get x by itself, we get:

x = 2

So the solution to the equation 2 - x = 0 is x = 2.

Equation 3: 9 + x - 0.7 = -0.7

To solve the equation 9 + x - 0.7 = -0.7, we need to isolate x.

First, let's simplify the equation by combining like terms:

x + 8.3 = -0.7

Next, we can isolate x by subtracting 8.3 from both sides of the equation:

x = -0.7 - 8.3

Simplifying further, we have:

x = -9

So the solution to the equation 9 + x - 0.7 = -0.7 is x = -9.

Therefore, the solutions to the given equations are: - For |x - 5| = 0, x = 5. - For 2 - x = 0, x = 2. - For 9 + x - 0.7 = -0.7, x = -9.
