Question

(1.2+0.1x)*4/5=6.56 срочно Помогите пожалуйста

Answer 1

1,2 + 0,1x = 6,56 : 4/5
0,1x = 6,56 : 0,8 - 1,2
0,1x = 7
x = 70

Answer 2

Solving the Equation (1.2 + 0.1x) * 4 / 5 = 6.56

To solve the equation (1.2 + 0.1x) * 4 / 5 = 6.56, we can follow these steps:

1. Isolate the Variable: - First, we can start by multiplying both sides of the equation by 5 to get rid of the fraction.

   5 * (1.2 + 0.1x) * 4 / 5 = 5 * 6.56
   

This will allow us to isolate the variable x.

2. Simplify and Solve: - After simplifying, we can solve for x.

   (1.2 + 0.1x) * 4 = 5 * 6.56
   

   4.8 + 0.4x = 32.8
   

   0.4x = 32.8 - 4.8
   

   0.4x = 28
   

   x = 28 / 0.4
   

   x = 70
   

Solution

The solution to the equation (1.2 + 0.1x) * 4 / 5 = 6.56 is x = 70.
