Question

Please help solve! I tried but I’m messing this up, would really appreciate it!

Answer 1

Answer:

K = $\frac{4r}{n} -a$ n $\neq 0$

Step-by-step explanation:

We have our equation $r = \frac{n}{4} (a+K)$ and are looking for K

First we have to switch sides :

$\frac{n}{4} (a+K) = r$

Since we have a denominator of 4, we multiply both sides by 4 :

$n (a+K) = 4r$

We then divide both sides by n :

$a+K = \frac{4r}{n} ; n\neq 0$

Subtract a from both sides :

$K = \frac{4r}{n} -a; n\neq 0$
