-2+3x=2x+6x+x

1. add like terms on right side of equal sign; 2x, 6x and x

-2+3x=9x

2. do the additive inverse of 3x on both sides of the equal sign (subtract 3 x on both sides)

-2=6x

3. do the multiplicative inverse of 6 on both sides (divide 6 from 6x and -2)

-2/6= x

4. simplify -2/6

x=-1/3

This question can be solved by applying the properties of similar triangles

the triangle with sides 5x and 20 is similar to the triangle with sides 45 and 36

therefore we can say

5x/45=20/36

x=5 units

Hope this helps

Alekssandra [29.7K]

Answer:

The volume inside the cylinder is $1152\pi\ cm^3$ .

Step-by-step explanation:

Given : Four spheres of radius 6 cm just fit inside a cylinder.

To find : Calculate the volume inside the cylinder that is empty ?

Solution :

The volume of the cylinder is volume of 4 spheres.

The volume of sphere is $V=\frac{4}{3}\pi r^3$

The radius is 6 cm.

The volume of four spheres is

$V=4\times \frac{4}{3}\times \pi\times (6)^3$

$V=1152\pi\ cm^3$

Therefore, the volume inside the cylinder is $1152\pi\ cm^3$ .
