Let's solve the given expression step by step:
5(0.5k - 1) + 2(0.4 - k)
= 5 * 0.5k - 5 * 1 + 2 * 0.4 - 2 * k [Using distributive property]
= 2.5k - 5 + 0.8 - 2k
= (2.5k - 2k) + (-5 + 0.8) [Combining like terms]
= 0.5k - 4.2
So, the answer is 0.5k - 4.2 (in decimal form).
5(0.5k - 1) + 2(0.4 - k)
= 5 * 0.5k - 5 * 1 + 2 * 0.4 - 2 * k [Using distributive property]
= 2.5k - 5 + 0.8 - 2k
= (2.5k - 2k) + (-5 + 0.8) [Combining like terms]
= 0.5k - 4.2
So, the answer is 0.5k - 4.2 (in decimal form).
