Answer:

r=9

Explanation:

6 2

---- = ------

r 3

We can use cross products to solve

6 * 3 = 2 * r

18 = 2r

Divide by 2

18/2 = 2r/2

9 = r

\bf{Hey\ there!}


\bold{(6)/(r)=(2)/(3)}


\text{First, you have to cross multiply}


\bullet{\ \bold{numerator* denminator}}


\bullet{ \ \bold{denominator* numerator}}


\bold{6*3=18}


\bold{2* r=2r}


\text{Your equation becomes: 2r = 18}


\text{\underline{DIVIDE}\ by 2 on each of your sides!}


\bold{(2r)/(2)=(18)/(2)}


\bf{Cancel:(2r)/(2)\ because\ it\ gives\ us the result\ of\ 1}


\bf{Keep:(18)/(2)\ because\ it\ gives\ us the\ value\ of\ r}


\bf{18/2=9}


\boxed{\boxed{\bold{Answer:x=9}}}
\checkmark


\text{Good luck on your assignment and enjoy your day!}
