A scientist used 2 gallons of liquid for every 3 hours he works. He used how much of a gallon each hour he works.

0.67 repeated or 2/3 gallons

Step-by-step explanation:

First you divide the gallons by hours because you are doing gallons per hour.

Then you get 0.66666667 and you convert that to fraction and that's your answer.

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
