Question

-0,8 (2c – 4,8) – 6,6• (5 + 0,5c​

Answer 1

Ответ:

-0,8 (2c – 4,8) – 6,6• (5 + 0,5c

Answer 2

It looks like you've provided a mathematical expression, but it's a bit unclear what you're asking. If you want me to simplify or solve the expression, please let me know. Here's the expression you provided:

$-0.8(2c - 4.8) - 6.6(5 + 0.5c)$

To simplify this expression, you can start by distributing the numbers outside the parentheses:

$-0.8 \times 2c + 0.8 \times 4.8 - 6.6 \times 5 - 6.6 \times 0.5c$

Now, simplify each term:

$-1.6c + 3.84 - 33 - 3.3c$

Combine the $c$ terms:

$-1.6c - 3.3c + 3.84 - 33$

$-4.9c - 29.16$

So, the simplified expression is:

$-4.9c - 29.16$

Answer 3

To simplify the given expression $-0.8(2c - 4.8) - 6.6(5 + 0.5c)$, you can start by applying the distributive property to remove the parentheses and then combine like terms. Here's how you do it step by step:

1. Distribute -0.8 into $2c - 4.8$: $= -0.8 \times 2c - (-0.8 \times 4.8)$ $= -1.6c + 3.84$

2. Distribute -6.6 into $5 + 0.5c$: $= -6.6 \times 5 - 6.6 \times 0.5c$ $= -33 - 3.3c$

Now your expression becomes: $-1.6c + 3.84 - 33 - 3.3c$

3. Combine like terms by adding $-1.6c$ and $-3.3c$: $-1.6c - 3.3c + 3.84 - 33$ $= -4.9c - 29.16$

So, the simplified expression is $-4.9c - 29.16$.
