Add: 5(0.5k−1)+2(0.4−k) . Answer should be in decimal form.

Answer 1

To solve this expression, we'll start by distributing the coefficients to the terms inside the brackets:

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

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

= 2.5k - 5 + 0.8 - 2k

Now, let's combine like terms:

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

= 0.5k - 4.2

Thus, the answer in decimal form is 0.5k - 4.2.
