Jose mixed 3mL of a chemical solution with every gallon of water for his aquarium. Kevin mixed 6mL of a chemical solution with every 3 gallons of water for his aquarium.

The answer is the second option, as 6:3 is less than 3:1

Step-by-step explanation:

To work this out, divide Kevins' ratio by 3 to work out how much of the chemical solution he uses per gallon:

        6:3 ÷ 3 = 2:1

This shows that he uses less chemical solution per gallon than Jose, as 6:3 is less than 3:1.

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
