Question

1,6(2p-k)-0,8(4p - 5k);​

Answer 1

Ответ:

2.4k

Пошаговое объяснение:

3.2p-1.6k-3.2p+4k = 2.4k

Answer 2

To simplify the expression 1.6(2p - k) - 0.8(4p - 5k), you can distribute the constants (1.6 and 0.8) across the terms inside the parentheses and then combine like terms. Here's how you can do it step by step:

1.6(2p - k) - 0.8(4p - 5k)

First, distribute 1.6 and 0.8 to the terms inside the parentheses:

= (1.6 * 2p) - (1.6 * k) - (0.8 * 4p) + (0.8 * 5k)

Now, simplify each of these products:

= 3.2p - 1.6k - 3.2p + 4k

Next, combine like terms:

(3.2p - 3.2p) + (-1.6k + 4k)

Since the 3.2p and -3.2p cancel each other out, you're left with:

0 + 2.4k

So, the simplified expression is:

2.4k
