Question

0,2(4х – 2,5) – 4(2,5 – 2х) + 0,3 =

Answer 1

Ответ:

Пошаговое объяснение:

0,2(4х – 2,5) – 4(2,5 – 2х) + 0,3 =0.8х-0,5-10+8х+0,3=8,8х-10,2

Answer 2

To solve the expression, we can follow these steps:

1. Distribute the constants (coefficients) to the terms inside the parentheses:

   0.2 * (4x - 2.5) - 4 * (2.5 - 2x) + 0.3

   Now, we have:

   0.2 * 4x - 0.2 * 2.5 - 4 * 2.5 + 4 * 2x + 0.3

2. Multiply the constants by the values inside the parentheses:

   0.8x - 0.5 - 10 - 8x + 0.3

3. Combine like terms:

   (0.8x - 8x) + (-0.5 - 10 + 0.3)

   Now, simplify further:

   -7.2x - 9.7 + 0.3

4. Add the constants:

   -7.2x - 9.7 + 0.3 = -7.2x - 9.4

So, the simplified expression is:

-7.2x - 9.4
