Answer:

x=-1/7

Step-by-step explanation:

$\frac{3x-1}{3} -\frac{2x}{x-1} =x$

$\frac{(3x-1)(x-1)}{3x-3} -\frac{2x(3)}{3x-3} =x$

$\frac{3x^2-4x+1}{3x-3} -\frac{6x}{3x-3} =x$

$\frac{3x^2-10x+1}{3x-3} =x$

$\frac{3x^2-10x+1}{3x-3} =\frac{x(3x-3)}{3x-3}$

$\frac{3x^2-10x+1}{3x-3} =\frac{3x^2-3x}{3x-3}$

$3x^2-10x+1=3x^2-3x$

$-10x+1=-3x$

$-7x=1$

$x=-1/7$

Answer:

Volume of Cone =

$= \frac{1}{3}\pi (2)^2 (4)\\\\=\frac{1}{3}(3.14)(4)(4)\\\\=\frac{1}{3}\times 3.14\times 16 \\\\=\frac{1}{3}\times50.24\\\\=16.746\\\\\approx16.75 \texttt {ft} ^3$

Thus, Volume = 16.75 cubic feet

Step-by-step explanation:

Volume of a cone is given by the formula

$V=\frac{1}{3}\pi r^2 h$

Where r is the radius and

h is the height

Given radius r = 2 and

height is 2 times that.

So height is 2*2 = 4

Plugging these into the formula we get:

Volume of Cone =

$= \frac{1}{3}\pi (2)^2 (4)\\\\=\frac{1}{3}(3.14)(4)(4)\\\\=\frac{1}{3}\times 3.14\times 16 \\\\=\frac{1}{3}\times50.24\\\\=16.746\\\\\approx16.75 \texttt {ft} ^3$

Thus, Volume = 16.75 cubic feet
