Answer:
Step-by-step explanation:
The first two steps are for the purpose of eliminating fractions. Doing so results in 4(2x - 5) = 9(x - 2), which is to be solved for x.
Perform the indicated multiplication, obtaining:
8x - 20 = 9x - 18.
Then combine like terms: -2 = x, or
x = -2.
To complete the formal check, substitute -2 for x in the first equation. This results in:
(1/3)(-4 - 5) = (3/4)(-2 -2), or
-3 = -3
... which is obviously true.
Answer:
Step-by-step explanation:
The volume of a cone is given by the following equation:
where 
is the volume of the cone, 
is the radius of the base, and 
is the height of the cone.
In the given problem, we know that 
and 
. Using this, we can find the volume of a single cone:
Since the problem asks how much foam is needed to make 120 cones, we can multiply this result to get our answer:
