Question

0,3(х+28)=-0,6(х-11)​

Answer 1

Ответ:

50

Пошаговое объяснение:

0.3(x + 28) = 0.6(x - 11)

0.5(x + 28) = x - 11

0.5x + 14 = x - 11

0.5x = 25

x = 50

Answer 2

Ответ:

х=16.6

Пошаговое объяснение:

0,3(х+28)=-0,6(х-11)

0,3х+8,4=-0,6х+6.6

0.3х+0.6х=6.6-8.4

0.9х=15

х=15/0.9

х=16.6

Answer 3

To solve the equation 0.3(x + 28) = -0.6(x - 11), you can follow these steps:

1. Distribute the constants on both sides of the equation: 0.3x + 0.3(28) = -0.6x - 0.6(11)

2. Simplify the equation: 0.3x + 8.4 = -0.6x - 6.6

3. Move the terms with x to one side of the equation and the constants to the other side. You can do this by adding 0.6x to both sides and subtracting 8.4 from both sides: 0.3x + 0.6x = -6.6 - 8.4

4. Combine like terms: 0.9x = -15

5. Finally, solve for x by dividing both sides by 0.9: x = -15 / 0.9

Now, calculate x:

x = -16.67 (rounded to two decimal places)

So, the solution to the equation is approximately x = -16.67.
