Answer X = 2
Step-by-step explanation:
-30 + -18 - X + - 24,
+ 30 +30
0 6
-18 -x = -6
DIVIDE
3 -x = -1
BRING THE 3 OVER TO THE NEGATIVE ONE
YOU GET
X = 2
Density = mass/volume
the mass is 10578.9 pounds
the volume of a sphere is v = 4/3 πr^3
v = (4/3) (π) (4.3)^3
v = 333.04
10578.9 / 333.04 = 31.76
the final density is 31.76!!
