Answer:

No, it does not.

Step-by-step explanation:

Okay so.
2/5=24/60 (multiply 2/5 by 12)
2/3=40/60 (multiply 2/3 by 20)
1/4=15/60 (multiply 1/4 by 15)
Then,
Add 24/60 with 40/60 which is 64/60 after you get that you subtract by 15/60 and you get 49/60.
Hope this helps!^^

(8,1) and (x,3) The pair of points is on the graph of an inverse variation. Find the missing value.

Gelneren [198K]

$\bf \qquad \qquad \textit{inverse proportional variation}
\\\\
\textit{\underline{y} varies inversely with \underline{x}}\qquad \qquad y=\cfrac{k}{x}\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------$

$\bf (\stackrel{x}{8},\stackrel{y}{1})\textit{ we know that }
\begin{cases}
x=8\\
y=1
\end{cases}\implies 1=\cfrac{k}{8}\implies 8=k
\\\\\\
therefore\qquad \boxed{y=\cfrac{8}{x}}
\\\\\\
(x,\stackrel{y}{3})\textit{ when y = 3, what is \underline{x}?}\qquad 3=\cfrac{8}{x}\implies x=\cfrac{8}{3}$
