Question

34k+(6.3−8.1k)÷0.9=22

Answer 1

Answer:

k = 0.6

Step-by-step explanation:

In this question, we need to find the value of k for the following expression. The expression is given as :

$34k+\dfrac{(6.3-8.1k)}{0.9}=22$

Solving LHS first,

$=34k+\dfrac{(6.3-8.1k)}{0.9}\\\\=\dfrac{30.6k+6.3-8.1k}{0.9}\\\\=\dfrac{6.3+22.5k}{0.9}$

i.e.

$\dfrac{6.3+22.5k}{0.9}=22\\\\6.3+22.5k=19.8\\\\22.5k=19.8-6.3\\\\k=\dfrac{13.5}{22.5}\\\\k=0.6$

So, the value of k is 0.6.
