He has 25.00 to spend.
He spends 4.25 to rent shoes.
He spends 2.50 for each game he bowls.

Which inequality can Manny use to determine , the greatest number of games he can bowl?

A: 2.5 + 4.25x ≥ 25
B; 4.25 + 2.5x ≥ 25
C: 2.5 + 4.25 ≤ 25
D: 4.25 + 2.5x ≤ 25

None of the options you showed are it.

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.
