Answer:

$y = 15$

Step-by-step explanation:

Given

$4 : 8 = y : 30$

Required

Find y

$4 : 8 = y : 30$

Express as fraction

$4 / 8 = y /30$

Multiply through by 30

$30 * 4 / 8 = y /30* 30$

$30 * 4 / 8 = y$

$15 = y$

$y = 15$

Answer:

$\frac{6}{k-6}$

Step-by-step explanation:

First, we can factor all of the following equations to turn that weird, huge looking thing into $\frac{(k+6)(k-6)}{(k-6)(k-10)}$ ÷ $\frac{(k-6)^2}{k(k-6)}$ × $\frac{6(k-10)}{k(k + 6)}$ . We know that division is simply multiplication by the reciprocal, so that whole equation will turn into $\frac{(k+6)(k-6)}{(k-6)(k-10)}$ × $\frac{k(k-6)}{(k-6)^2}$ × $\frac{6(k-10)}{k(k+6)}$ . Now we can cancel out some values if they are both in the numerator and denominator, which will turn that still huge looking thing into $\frac{6}{k-6}$ which is our final answer, as it cannot be simplified further.
