Answer 1

Ответ:

-9х +178+24*13у

Пошаговое объяснение:

-2(4,5x – 89) +0,8(13y30)​=

-9х+178+0.8(30*13у)=
-9х+178+0.8*30*13у=

-9х +178+24*13у

Answer 2

To simplify the expression, let's expand and simplify each term:

-2(4,5x - 89) + 0,8(13y30)

First, distribute -2 to each term inside the parentheses:

-2 * 4,5x = -9x -2 * (-89) = 178

The expression becomes:

-9x + 178 + 0,8(13y30)

Next, distribute 0,8 to each term inside the parentheses:

0,8 * 13y = 10,4y 0,8 * 30 = 24

The expression now becomes:

-9x + 178 + 10,4y + 24

Combining like terms, we have:

-9x + 10,4y + 178 + 24

Finally, simplify further:

-9x + 10,4y + 202
