Hey you! wanna stop scrolling and me out really quickly? ! brainliest answer included! how many gallons of a 60% antifreeze solution must be mixed with 60 gallons of 15% antifreeze to get a mixture that is 50% antifreeze? use the six-step method.

I don't know the six step method

x (.60) + 60 (.15) = (x+60) .50

distribute

.60x +9 = .5x +30

subtract  .5x from each side

.1x +9 = 30

subtract 9 from each side

.1x = 21

divide by .1

x = 210

You will need 210 gallons of 60% antifreeze

6/20
