Question

12,5 + 149,6 : (1,36 + 56y)=112,5

Answer 1

Ответ:

17/7000

Пошаговое объяснение:

12,5 + 149,6 : (1,36 + 56у) = 112,5

149,6 : (1,36 + 56у) = 112,5 - 12,5

149,6 : (1,36 + 56у) = 100

1,36 + 56у = 149,6 : 100

1,36 + 56у = 1,496

56у = 1,496 - 1,36

56у = 0,136

у = 0,136 : 56

у = 136/1000 * 1/56

у = 136/56000

у = 17/7000

Answer 2

To solve for the variable "y" in the equation:

12.5 + 149.6 / (1.36 + 56y) = 112.5

First, let's isolate the term containing "y" on one side of the equation. Here are the steps:

1. Start by subtracting 12.5 from both sides:

   149.6 / (1.36 + 56y) = 112.5 - 12.5 149.6 / (1.36 + 56y) = 100

2. Now, let's get rid of the fraction. Multiply both sides of the equation by (1.36 + 56y):

   (1.36 + 56y) * (149.6 / (1.36 + 56y)) = 100 * (1.36 + 56y)

The left side simplifies as the (1.36 + 56y) terms cancel out:

149.6 = 100 * (1.36 + 56y)

3. Distribute 100 on the right side:

   149.6 = 136 + 5600y

4. Subtract 136 from both sides to isolate the term with "y":

   149.6 - 136 = 5600y

   13.6 = 5600y

5. Finally, divide both sides by 5600 to solve for "y":

   y = 13.6 / 5600

Now, you can simplify this fraction or express it as a decimal:

y ≈ 0.00242857143 (rounded to 8 decimal places)

So, the approximate value of "y" that satisfies the equation is 0.00242857.
