Answer: Choice A
The volume expression is 4/3 times pi times (3x)^3
===================================================
The volume of a sphere is found through the formula
V = (4/3)*pi*r^3
so we start with the fraction 4/3, multiply it with pi, and then multiply it with r^3
In this case, the radius is r = 3x because this is half of the diameter d = 6x
We simply replace the r with 3x in that formula above
V = (4/3)*pi*r^3
V = (4/3)*pi*( r )^3
V = (4/3)*pi*(3x)^3 ... replace r with 3x
2X-2=2X+9
Add 2
2X=2X+11
Subract 2X
0= 11
This has no solution to this problem
Answer:
6y=12x+18
Step-by-step explanation:
Y=Mx+b
To find the answer,we can set up two equations:
Let the integer be x and y seperately,and x be the larger number:
x+y=74
y=74-x....(1)
x-2y=26...(2)
Put (1) into (2):
x-2(74-x)=26
x-148+2x=26
3x=26+148
x=174/3
x=58
Put the above answer into (1):
y=74-58
y=16
Therefore,the answer is x=58, y=16.
Hope it helps!
