So with this equation, since the volume of the cylinder is 96 pi, plug that into the V variable, and since the radius of one of the marbles is 3, plug that into the r variable. From here, we can solve for x: 
Firstly, solve the parentheses: 
Next, multiply 36 pi and x: 
Next, subtract 24 pi on both sides: 
Lastly, divide both sides by 36 pi, and your answer will be 
, or B.
C. polygons!!
the polygons it is made of are called faces. the edges of the faces are called the edges of the polyhedron
Answer:
Simultaneous equations are two or more algebraic equations that share variables e.g. x and y . They are called simultaneous equations because the equations are solved at the same time. Each of these equations on their own could have infinite possible solutions.
Good evening ,
Answer:
<h2>8 chickens</h2><h2>8 horses</h2>
Step-by-step explanation:
let c = the number of chickens
let h = the number of horses
You have to solve this system
h + c = 16
4h + 2c = 48
h + c = 16 ⇒ h = 16 - c
If we substitute h=16-c in the second equation we will get :
4(16-c)+ 2c = 48
Then 64 - 4c + 2c = 48
Then 2c = 64 - 48 = 16
Then c = 8
Since h = 16 - c then h = 16 - 8 = 8
