5 less than the quotient of a number and 3 is -7

1 answer:

6 0

$\frac{x}{3}$ - 5 = -7 .
____________________________________________
This would be one way to write the expresion/equation; in which "x" represents the unknown number.

Now, to solve for "x" ;
____________________________________________
Given:
____________________________________________
$\frac{x}{3}$ - 5 = -7 ;

Add "5" to EACH SIDE of the equation:
_____________________________________________
$\frac{x}{3}$ - 5 + 5 = -7 + 5 ;

to get:

$\frac{x}{3}$ = -2 ;

x = (-2 * 3) ;
_________________________________
x = - 6 .

The radius r of a cone is increasing at a rate of 4in/min. The height h of the cone is always 4 times the radius. Find the rate

AlekseyPX

$\bf \textit{volume of a cone}\\\\
V=\cfrac{\pi r^2 h}{3}\qquad h=4r\implies V=\cfrac{\pi r^2 \cdot 4r}{3}\implies V=\cfrac{4\pi r^3}{3}\\\\
-----------------------------\\\\
\cfrac{dv}{dt}=\cfrac{4\pi }{3}\cdot 3r^2\cdot \cfrac{dr}{dt}\implies \cfrac{dv}{dt}=4\pi r^2\cdot \cfrac{dr}{dt}\qquad 
\begin{cases}
\frac{dr}{dt}=4\\\\
r=7
\end{cases}
\\\\\\
\cfrac{dv}{dt}=4\pi (7)^2\cdot 4$
