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

1 answer

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.
