The local school sponsored a mini-marathon and supplied 40 gallons of water per hour for the runners. what is the amount of water in quarts per hour? 10 qt/h 160 qt/h 320 qt/h 80 qt/h

Find the x-intercept and y-intercept of the line. 3x + 5y = −15

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)

3x = 729 solve for x plz . it's urgent. will mark
