Answer:
x = 2
Step-by-step explanation:
Add 2x from each side giving you
7x - 3 = 11
Add 3 to each side
7x = 14
Divide by 7
x = 2
The space between the two spheres will be the volume of the larger sphere minus the volume of the smaller sphere. Given that the volume of any sphere is:
V=(4πr^3)/3 The space between to sphere of different radius and positioned about the same center is:
S=(4πR^3)/3-(4πr^3)/3 I used S=volume of space, R=larger radius and r=smaller radius...
S=(4π/3)(R^3-r^3), we are told that R=5 and r=4 so
S=(4π/3)(5^3-4^3)
S=(4π/3)(125-64)
S=(4π/3)(61)
S=244π/61
S=4π cm^3
S≈12.57 cm^3 (to nearest hundredth of a ml)
Answer:

1, 7
just do
3, 1
2, 4
and see what you have to do to get to that mid point. you need to go down one to get to 2 from 3 and you have to go +3 to get to 4 from 1. so you need to go down 1 for x and + 3 for y
hope that made sense
