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

Answer 1

To solve the given expression 5(0.5k-1) + 2(0.4-k), we can simplify it step by step:

First, distribute the coefficients:
5(0.5k-1) + 2(0.4-k) = 2.5k - 5 + 0.8 - 2k

Next, combine like terms:
2.5k - 5 + 0.8 - 2k = (2.5k - 2k) + (0.8 - 5) = 0.5k - 4.2

Therefore, the simplified form of 5(0.5k-1) + 2(0.4-k) is 0.5k - 4.2.

Answer 2

is it 2.45

Answer 3

Apologies for the confusion in my previous response. Upon recalculating, the simplified form of the expression 5(0.5k-1) + 2(0.4-k) is 0.5k - 4.2, not 2.45.
