Answer:

Step-by-step explanation:
We can solve this system just by summing each side of the equation:
So, both left sides will be sum, and both right sides too.
The resulting expression will be:

Ordering and solving both sides:

Hence, the value to the system is 
It's important to combine both equation, because the exercise is asking for the solution of the system.
Answer:
24 cm
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
2304 pi = 4/3 pi r^3
Divide each side by pi
2304 = 4/3 r^3
Multiply each side 3/4
2304 * 3/4 = 4/3 r^3 * 3/4
1728 = r^3
Take the cube root of each side
1728 ^ 1/3 = r^3 ^ 1/3
12 = r
We want the diameter
d = 2*r
d = 2*12
d = 24
Answer:
A
Step-by-step explanation:

Expand parentheses:

Move all y's to one side and numbers to the other:

Divide both sides by -6. Since you are dividing both sides by a negative number, you need to flip the comparator:
