Answer:
We conclude that the value of k represented as a decimal rounded to the nearest tenth is: 
Step-by-step explanation:
Given the expression

We need to determine the value of k, represented as a decimal rounded to the nearest tenth.
Let us solve the expression

Apply cross-function multiply: if
then 

∵ 7 · 12= 84
Divide both sides by 5

Simplify

(Rounded to the nearest 0.1 or the Tenths Place)
Therefore, we conclude that the value of k represented as a decimal rounded to the nearest tenth is:
