Y : x is the same as y/x substitute 16/20= y/x cross multiply 20 y= 16 x y= 16x/20 reduce the fraction y= 4/5x

the difference between the heights of your chair and your desk is -10 1/4 inches. the height of your desk is 29 3/4 inches. what

OLEGan [10]

Since you said the height of your chair and you desk, chair would go first when subtracting.
C= chair
c - 29.75 = -10.25
+ 29.75 = + 29.75
c= 19.5
So, you chair is 19.5 (19 1/2) inches tall.

The pair of points is on the graph of an inverse variation. Find the missing value. (1.6, 6) and (8, y) 0.03 30 1.2 0.83

ZanzabumX [31]

One may note that (1.6 , 6) is just another way to say x = 1.6 when y = 6.

and that (8 , y) is another way to say x = 8 and y is who knows.

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

$\bf \textit{we know that }
\begin{cases}
x=1.6\\
y=6
\end{cases}\implies 6=\cfrac{k}{1.6}\implies 6(1.6)=k\implies 9.6=k
\\\\\\
\qquad therefore\qquad \boxed{y=\cfrac{9.6}{x}}
\\\\\\
\textit{when x = 8, what is \underline{y}?}\qquad y=\cfrac{9.6}{8}$
