Question

4(-0,2х+5у) - (10у - 0,8х)

Answer 1

Ответ:

4(-0,2х+5у) - (10у - 0,8х) = -0,8x+20y-10y+0.8x = 10y

Answer 2

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

4(-0.2x + 5y) - (10y - 0.8x)

First, let's distribute the 4 to each term inside the parentheses:

= -0.8x + 20y - (10y - 0.8x)

Now, let's remove the parentheses around the second expression by distributing the negative sign:

= -0.8x + 20y - 10y + 0.8x

Notice that the terms -0.8x and +0.8x cancel each other out, leaving us with:

= 20y - 10y

Combining like terms, we get:

= 10y

Therefore, the simplified form of the expression 4(-0.2x + 5y) - (10y - 0.8x) is 10y.
