Question

0,1х+0,3(х+0,3)=0,001​

Answer 1

Ответ:

$-0,2225$

Пошаговое объяснение:

$0,1x+0,3(x+0,3)=0,001;$

$0,1x+0,3x+0,09=0,001;$

$0,4x=-0,09+0,001;$

$0,4x=-0,089;$

$\frac{2}{5}x=-\frac{89}{1000} \quad | \quad \cdot \frac{5}{2}$

$x=-\frac{89 \cdot 5}{200 \cdot 5 \cdot 2};$

$x=-\frac{89}{400};$

$x=-\frac{88+1}{400};$

$x=-(\frac{88}{400}+\frac{1}{400});$

$x=-(\frac{22}{100}+0,0025);$

$x=-(0,22+0,0025);$

$x=-0,2225;$

Answer 3

To solve the equation 0.1x + 0.3(x + 0.3) = 0.001, you can follow these steps:

1. Distribute the 0.3 on the left side of the equation:

   0.1x + 0.3x + 0.09 = 0.001

2. Combine like terms on the left side:

   0.4x + 0.09 = 0.001

3. Subtract 0.09 from both sides of the equation to isolate the x terms:

   0.4x = 0.001 - 0.09

4. Simplify the right side:

   0.4x = -0.089

5. Now, divide both sides by 0.4 to solve for x:

   x = (-0.089) / 0.4

6. Calculate the result:

   x = -0.2225

So, the solution to the equation is x = -0.2225.
