The answers are 8/10, 12/15, 16/20
Answer:
x = 8
y = 1
Step-by-step explanation:
First you want to substitute y in for 1 to get
2x + 4 = 20
Then subtract four to both sides to get
2x = 16
Then divide 2 by 16 to get
x = 8
and then plug the 8 into the original equation
2(8) + 4y = 20
And then solve for y!
So basically, he wants to make mixture where lemon=lime
it is 6 gallons so
40% of 6=0.4 times 60=2.4=lemon
60% of 6=0.6 times 60=3.6=lime
so to make them equal
3.6-2.4=1.2
he must add 1.2 gallons of 100% lemon juice to make a mixture of 50% lemon and 50% lime
1.2 gallons is the answer
