Add 5(0.5K - 1) + 2 (0.4 - K) answer should be in decimal form

Answer 1

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

5(0.5K - 1) + 2(0.4 - K) = 2(0.4 - K) + 5(0.5K - 1)

Now, let's distribute the coefficients:

= 2(0.4) - 2K + 5(0.5K) - 5(1)

Simplifying further:

= 0.8 - 2K + 2.5K - 5

Combining like terms:

= -2K + 2.5K + 0.8 - 5

= 0.5K - 4.2

Thus, the simplified expression is 0.5K - 4.2.
