When entering solutions in interval notation, note: If there is no solution, enter DNE
If it is infinite solutions, enter (-00,00)
Use "U" symbol for OR

Solve the compound inequality and enter the correct solution in interval form:
3(x - 5) +2 <
- 19 OR 43 +1> 1

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.

The equation i believe is 4+ i am not sure about the part: the number of weeks in a group of days so i can't you on that part
