3 answers

To find the decimal form of the expression, we need to evaluate the expression by performing the operations.

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

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

= 2.5k - 5 + 0.8 + 2k

Combining like terms, we have:

= 2.5k + 2k - 5 + 0.8

= 4.5k - 4.2

Thus, the decimal form of the expression 5(0.5k - 1) + 2(0.4 - k) is 4.5k - 4.2.
