A hot tub holding 480 gal of water begins to empty at a rate of 5 gal/min. At the same time, an empty hot tub begins to fill at a rate of 15 gal/min. Let g represent the number of gallons of water and let t represent time in minutes. The system models this situation. How long will it take for the hot tubs to hold equal amounts of water, and how much water will that be? g = 480 – 5t g = 15t It will take ? minutes for both hot tubs to hold equal amounts of water. They will each hold ? gallons. i give medals
do you know how to solve systems of equations
nope all blank
how did your teacher tell you to solve these
im homeschooled so i dont understand how to learn with them
oh..
Well if you graph both equations letting g=y and t=x, the point where they intersect will be your solution
You can also use substitution g = 480 – 5t ... start with the first equation 15t = 480 - 5t ... replace 'g' with '15t' now solve for t
refresh the page if you see weird symbols show up
ohkay, i got it know thanks guys
