I am not sure what the six-step method looks looks like but if you use x gallons of 60% solution
the amount of antifreeze in the mixture = 0.6x + 8 gallons
This needs to be 50% of the total quantity in the mixture, x + 80
0.6x + 8 = 0.5(x + 80)
0.6x + 8 = 0.5x + 40
0.6 - 0.5 = 40 - 8
0.1x = 32
x = 32 x 10 = 320 gallons
C and D because I just know
Step-by-step explanation:
13 hours
6 + 4 + 3 = 13
correct if wrong
36/15 = 8/a
multiply a .. on both sides
a×36/15= 8
multiply 36/15 reciprical on both sides
a= 8 × 15/36
a= 120/36
a= 3.33
