Question

1)2(3x+5c-a) 2)-0,5(2a+0,4y-7,6x)

Answer 1

Пошаговое объяснение:

1)

$2(3x + 5c - a) = 6x + 10c - 2a$

2)

$- 0.5(2a + 0.4y - 7.6x) = - a - \frac{1}{5} y + 3.8x$

Answer 2

1) 6x+10c-2a

2)-a-0,2y+3,8x

Answer 3

It looks like you want to simplify two expressions. Let's simplify each expression step by step:

1. 2(3x + 5c - a)

To simplify this expression, you need to distribute the 2 to each term inside the parentheses:

2 * 3x + 2 * 5c - 2 * a

Now, simplify each term:

6x + 10c - 2a

So, the simplified form of the first expression is 6x + 10c - 2a.

2. -0.5(2a + 0.4y - 7.6x)

To simplify this expression, distribute the -0.5 to each term inside the parentheses:

-0.5 * 2a - 0.5 * 0.4y + 0.5 * 7.6x

Now, simplify each term:

-1a - 0.2y + 3.8x

So, the simplified form of the second expression is -a - 0.2y + 3.8x.
