Question

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

Answer 1

To solve the expression, we can distribute and simplify:

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

= 2.5k - 5 + 0.8 - 2k

Now, combine like terms:

= (2.5k - 2k) + (0.8 - 5)

= 0.5k - 4.2

So, the answer in decimal form is 0.5k - 4.2.
