Answer: k = 5/2

Step-by-step explanation:

Hi, to answer this question we have to solve for "k":

2.5(4k+2) =12k

Applying distributive property:

2.5(4k) + 2.5(2) =12k

10k +5 =12k

Combining alike terms:

5 = 12k -10k

5= 2k

Isolating the variable "k"

5/2=k

k = 5/2 or 2.5 (decimal form)

Feel free to ask for more if needed or if you did not understand something.
