Last question, really confused.

The green family is a family of six people. they have used 4,885.78 gallons of water so far this month. they cannot exceed 9,750.05 gallons per month during drought season. write an inequality to show how much water just one member of the family can use for the remainder of the month, assuming each family member uses the same amount of water every month.

The weight of an object in the water is 7% of its weight out of the water. what is the weight of a 652g object in the water?

What is the solution to this system of equations? y= 2x - 3.5 x - 2y = -14
