To simplify the expression, we can distribute the coefficients:
5(0.5k - 1) + 2(0.4 - k) = 2(0.4 - k) + 5(0.5k - 1)
Which can be further simplified:
= 2(0.4) - 2k + 5(0.5k) - 5(1)
= 0.8 - 2k + 2.5k - 5
Next, we can combine like terms:
= -2k + 2.5k + 0.8 - 5
= (2.5k - 2k) + (0.8 - 5)
= 0.5k - 4.2
Therefore, the simplified expression is 0.5k - 4.2.
Add 5(0.5k-1)+2(0.4-k)
