What is the value of c in the equation below?
BRE
3
5
125
0625

(x) - (y) = (1 + 4i)

(3 + 6i) - (2 + 2i) = (1 + 4i)

Planet earth has a mass of 5.9726x10²⁴ kg.then: 5.9726x10²⁴ kg=100% of the total earth mass.if the water´s mass=5x10-4 % of the total mass, we can solve this problem by the rule of three.5.9726x10²⁴ %*10⁻⁴ %x=(5.9726x10²³ kg)(5*10⁻⁴  %) / 100 %=2.9863x10¹⁹ kganswer:   the mass of the planet´s water would be   2.9863 x 10¹⁹ kg.

Ok so the answer for this question is b im 100 percent sure.
