Answer:
60 gallons of 70% antifreeze
Step-by-step explanation:
Let n be the amount of 70% antifreeze. And the second brand was 45% pure anti freeze Then:
According to the question
0.7 n+.45(150-n)=0.55(150)
0.7 n+67.5-0.45 n=82.5
0.25×n=15
n=15/.25 = 60
You need 60 gallons of 70% antifreeze, and 90 gallons of 45% antifreeze for this mixture
2/3y-4=x
2/3y*3/2=(x+4)*3/2
y=1.5x+6
