Answer:
33x-25
Step-by-step explanation:
2(3x-5)-3(6-4x)+(15x+3)
6x-10-18+12x+15x+3
21x+12x-10-18+3
=33x-25
4 thousands = 4,000
21 tens = 21*10 = 210
210 + 4,000 = 4,210
Answer: 4,210

Answer:
Step-by-step explanation:
The formula for the volume of a sphere is
In order to use this formula we have to have a value for the radius and right now we don't. But we can find it indirectly by using the circumference formula. The circumference formula is
If the circumference is 20π, then we will fill that in for "C" and solve for r:
20π = 2πr and if you divide both sides by 2π, you'll get that r = 10. Now we have a radius.
Using that in the volume formula:
and then simplifying a bit:
and
which divides to give you
, third choice down.
