Answer:

The value of x is 7.

Step-by-step explanation:

First, you have to make the left side into 1 fraction by making the denormintor the same and make it into simplest form :

$\frac{x}{3} + \frac{x}{6}$

$= \frac{x \times 2}{3 \times 2} + \frac{x}{6}$

$= \frac{2x}{6} + \frac{x}{6}$

$= \frac{2x + x}{6}$

$= \frac{3x}{6}$

$= \frac{x}{2}$

Next you have to multiply both sides by 2 in order to make x the subject :

$\frac{x}{2} = \frac{7}{2}$

$\frac{x}{2} \times 2 = \frac{7}{2} \times 2$

$x = 7$

The value of the solid's surface area is equal to the value of the solid's volume. Find the value of x.

USPshnik [31]

Volume = (l * w * h) or (11 * 3 * x) which will equal surface area. Volume is 33x for now

Surface Area = 2 (x * 11) + 2 (x * 3) + 2 (11 * 3)

Set Volume equal to surface area. I simplified SA already.
33x = 22x + 6x + 66

33x - 28x = 66

5x = 66

x = 66/5 or 13.2
