The first thing you want to do is isolate the (x)s.

0.6x-5=0.1x+7
0.5x-5=7 (subtract 0.1x from both sides)
0.5x=12 (add 5 to both sides)
x=24 (divide both sides by 0.5)

Hope this helps!

Solve for x. show your work.

Hello!

$\large\boxed{x = 8}$

The two angles pictured are corresponding angles, so they are congruent.

Therefore:

17x - 4 = 12 + 15x

Isolate for x by subtracting 15x from both sides:

2x - 4 = 12

Add 4 to both sides:

2x = 16

Divide both sides by 2:

x = 8.

Volume of cylinder is 3 times of volume of cone having same base diameter and same height.

Solution:

Given that

A cylinder and A cone have the same diameter = 10 inches and same height = 12 inches

Need to find the relationship between volume of cylinder and cone.

Let’s calculate volume of each object separately first.

Calculation of volume of cylinder :

Formula of volume of cylinder is given as:

$V_{c y}=\pi r^{2} h$

Where π=3.14

$\text { radius } r=\frac{\text {diameter}}{2}=\frac{10}{2}=5 \text { inches }$

height h = 12 inches

On substituting given values in formula of cylinder we get

$\begin{array}{l}{V_{c y}=3.14 \times 5^{2} \times 12=942 \text { cubic inches }} \\\\ {\text { Volume of cylinder }=V_{c y}=942 \text { cubic inches }}\end{array}$

Calculation of volume of cone:

Formula of volume of cone is given as:

$V_{c o}=\frac{\pi r^{2} h}{3}$

Here π=3.14

$\begin{array}{l}{\text { radius } r=\frac{\text { diameter }}{2}=\frac{10}{2}=5 \text { inches }} \\\\ {\text { height } \mathrm{h}=12 \text { inches }}\end{array}$

On substituting given values in formula of cone we get

$V_{c o}=\frac{3.14 \times 5^{2} \times 12}{3}=314 \text { cubic inches }$

$\text { Volume of cone }=V_{c o}=314 \text { cubic inches }$

On comparing the two volumes we get

$V c y: V c o=942: 314=3: 1$

Hence can conclude that Volume of cylinder is 3 times of volume of cone having same base diameter and same height.
