Question

0,6(4х-18)-0,4(5-7х) х=1 Решите ПЖ

Answer 1

Ответ:

Пошаговое объяснение:

0,6(4х-18)-0,4(5-7х)=2,4х-10,8-2+2,8х=

5,2х-12,8

5,2*1-12,8=-7,6

Answer 2

Ответ:

0,6(4х-18)-0,4(5-7х) = y

Подставим х = 1.

0,6(4-18) - 0,4(5-7) = y

-8,4 + 0,8 = y

y = -7,6

Answer 3

To solve the expression ПЖ (assuming ПЖ means an equation or expression), we need to substitute the value of x with 1 and then calculate the result.

The given expression is: 0.6(4x - 18) - 0.4(5 - 7x)

Let's plug in x = 1:

0.6(41 - 18) - 0.4(5 - 71) 0.6(4 - 18) - 0.4(5 - 7) 0.6(-14) - 0.4(-2) -8.4 + 0.8 -7.6

So, when x = 1, the value of the expression ПЖ is -7.6.
