Add 5(0.5k-1) + 2(0.4-k

Answer 1

To simplify the expression 5(0.5k-1) + 2(0.4-k), we can distribute the coefficients:

5 * 0.5k - 5 * 1 + 2 * 0.4 - 2 * k

In the first term, 5 * 0.5k = 2.5k
In the second term, 5 * 1 = 5
In the third term, 2 * 0.4 = 0.8
In the fourth term, 2 * k = 2k

Now we can rewrite the simplified expression:

2.5k - 5 + 0.8 - 2k

Next, combine like terms:

(2.5k - 2k) + (-5 + 0.8)

The like terms are combined separately:

0.5k - 4.2

Therefore, the simplified expression is 0.5k - 4.2.
