To find x, you divide both sides of the equation by 12.20. This would look like this:
12.20x/12.20 =372.10/12.20 . Then, the answer you get is 30.5, so. X=30.5
There 16 cups in a gallon, so it would be 16×.05 times the number of days in a week which is 7 so it would be 16×.05×7
Would it be 270? if you take 90 3 times. due to that there are 3 different durations.
