3x-10=7x+2
Subtract 2 from both sides
3x-12=7x
Subtract 3x from both sides
-12=4x
Divide both sides by 4
X=-3
Hope this helped:)

3x-10=7x+2      First you have to subtract 2 from both sides  

3x-12=7x          Then subtract 3x from both sides  

-12=4x              Lastly, divide both sides by 4

And the answer is X=-3

The figure is made up of a cylinder and a cone. What is the volume of the composite figure? Use 3.14 for Pi. Round to the neares
Delvig [45]

Answer:

The volume of figure is 310.86 cm³

Step-by-step explanation:

First, you have to calculate the volume of cone and cylinder seperately by applying the formulas :

Cone,

v =  \frac{1}{3}  \times \pi \times  {r}^{2}  \times h

let \: \pi = 3.14 \\ let \: r = 3 \\ let \: h = 9

v =  \frac{1}{3}  \times 3.14 \times  {3}^{2}  \times 9

v = 84.78 \:  {cm}^{3}

Cylinder,

v = \pi \times  {r}^{2}  \times h

let \: \pi = 3.14 \\ let \: r = 3 \\ let \: h = 8

v = 3.14 \times  {3}^{2}  \times 8

v = 226.08 \:  {cm}^{3}

Next, you have to add up both volumes as the figure are made from cone and cylinder :

v = 84.78 + 226.08

v = 310.86  \: {cm}^{3}
