Answer:
a=1 c=3 b=3
Step-by-step explanation:
You would first divide by 5y which equals 96, so x equals 96. Hope this helped! :)
480=x+5y
480/5y=x+5y/5y
96=x
A- 678.25 grams
B- 200 grams
C- 5 rolls
Answer:
Step-by-step explanation:
If we let x = the amount of 5% solution and y = the amount of pure alcohol, we can set up that
.05x+y is the amount of alcohol in our resulting mixture, and x+y is the total amount in our resulting mixture (which we know is 380)
so we also know that:
(.05x+y)/380 = .6
If we simplify this we come up with:
.05x+y=228
and we know x+y=380
If we solve this as a system of equations, we will find that:
x=160 ml
y=220 ml
