Answer:

x = -12

Step-by-step explanation:

$\dfrac{5}{x - 3} = \dfrac{7}{x - 9}$

Cross multiply.

7(x - 3) = 5(x - 9)

7x - 21 = 5x - 45

2x = -24

x = -12

The price of an item has risen to $136 today. Yesterday it was $80. Find the percentage increase.

Natalka [10]

well, the numeric difference will be 136 - 80 = 56, now, if we take 80 (original price) to be the 100%, what is 56 (the increase) in percentage off of it?

$\begin{array}{ccll} amount&\%\\ \cline{1-2} 80&100\\ 56&x \end{array}\implies \cfrac{80}{56}=\cfrac{100}{x}\implies \cfrac{10}{7}=\cfrac{100}{x} \\\\\\ 10x=700\implies x = \cfrac{700}{10}\implies x = \stackrel{\%}{70}$
