Simply cross-multiply about,
Answer:
C
Step-by-step explanation:
The rubber exercise ball is a sphere
the volume of a sphere= 4/3*pi*r3
where r = the radius of the sphere.
from the diagram, the radius = 4.5inches
Therefore, volume of the rubber ball = 4/3*pi*4.5^3 = 381.51 cubic inches
2.2=4
2.7=14
5-4+14-5=1+14-5=15-5=10
Good Luck!
13+(-12-(-5)
13+(-12+5)
13+(-7)

Answer:
x=-5
Step-by-step explanation:
25-3x=40
-3x=40-25 (both side -25)
-3x=15 (both side divide by 3)
x=5
