Question

8,36 - 5,36 : (0,2к+0,47к) = 75,6

Answer 1

8,36-5,36:(0,2+0.47)=
1) 0,2+0,47=0,67
2) 5,36:0,67=8
3) 8,36-8=0,36  вот так правельнее по действиям!!!

Answer 2

To solve this equation, you can follow these steps:

1. Start by simplifying the expression inside the parentheses: 0.2k + 0.47k = 0.67k

2. Now, rewrite the equation with this simplified expression: 8.36 - 5.36 / 0.67k = 75.6

3. Next, subtract 5.36 from 8.36: 3 / 0.67k = 75.6

4. Divide both sides of the equation by 3 to isolate the fraction: (3 / 0.67k) / 3 = 75.6 / 3

5. Simplify the left side: 1 / 0.67k = 25.2

6. Now, isolate the variable k. To do this, take the reciprocal of both sides of the equation: 0.67k = 1 / 25.2

7. Finally, solve for k by dividing both sides by 0.67: k = (1 / 25.2) / 0.67

Now, calculate k:

k = (1 / 25.2) / 0.67 ≈ 0.0597

So, the value of k is approximately 0.0597.
