Well, if you look into it, inspect element thsi, really. I believe it is either A, Or C. But I am more strong with A.
Answer:
-12
First Solve second equation for x.
Plug this number in the first equation to get the y
x = -3
y = 4
x times y = -12
Answer:
Step-by-step explanation:
Assume as a basis the final mixture is 1000 mL. That means 399 mL of alcohol
Let x = mL of Soln A and y = mL of soln B.
x = 2y.
Now x + y = 1000
and 0.2x + 0.17y = 399
but x = 2y so 0.4y + 0.17y = 399
0.57y = 399.
y = 700 mL (That is your mL of solution B)
