Question

12.5+149.6:(1.36+56у)=112.5

Answer 1

Ответ:

12,5+149,6/(1,36+56у)=112,5

12,5+149,6/1,36+56у=112,5

12,5+110+56у=112,5

122,5+56у=112,5

122,5-112,5=56у

10=56у

10/56(это дробь!!)=у

Answer 2

To solve the equation 12.5 + 149.6 / (1.36 + 56у) = 112.5, we'll follow the order of operations (PEMDAS/BODMAS).

First, let's simplify the expression inside the parentheses: 1.36 + 56у = 1.36 + 56y

Now, let's substitute this expression back into the original equation: 12.5 + 149.6 / (1.36 + 56у) = 112.5

12.5 + 149.6 / (1.36 + 56у) = 112.5

Next, we'll isolate the fraction on the left side of the equation by subtracting 12.5 from both sides: 149.6 / (1.36 + 56у) = 112.5 - 12.5

149.6 / (1.36 + 56у) = 100

To remove the fraction, we can multiply both sides of the equation by (1.36 + 56у): 149.6 = 100 * (1.36 + 56у)

149.6 = 136 + 5600у

Now, let's isolate the variable (у) by subtracting 136 from both sides: 149.6 - 136 = 5600у

13.6 = 5600у

Finally, divide both sides by 5600 to solve for у: у = 13.6 / 5600

у ≈ 0.002428571429

Therefore, the approximate solution for у is 0.002428571429.
