Question

2,5 ⋅ (4х – 2,8) = 0,75

Answer 1

Ответ:

2,5*(4х-2,8) = 0,75

10х-7 = 0,75

10х = 0,75+7

10х = 7,75

х = 7,75 :  10

х = 0,775

Ответ: х = 0,775

Answer 2

To solve for x in the equation 2.5 * (4x - 2.8) = 0.75, you can follow these steps:

1. Distribute the 2.5 on the left side of the equation:

   2.5 * 4x - 2.5 * 2.8 = 0.75

2. Simplify both sides of the equation:

   10x - 7 = 0.75

3. Add 7 to both sides of the equation to isolate the term with x on the left side:

   10x - 7 + 7 = 0.75 + 7

   10x = 7.75

4. Finally, divide both sides by 10 to solve for x:

   10x / 10 = 7.75 / 10

   x = 0.775

So, the solution to the equation is x = 0.775.
