The answer MIGHT be 0, but 0/3 is also undefined.
Answer:10 liter * 20%= x liter*40% + (10- x) liter*5%
10l * 20%= x liter * 35% + 10 liter*5%
x liter *35 = 10l * 20 - 10l *5= 10l*15
x liter = 10l *15/35= 4.28 L= 4.3L
The volume of 40% solution= 4.3L
The volume of 5% solution= 10L- 4.3L= 5.7L
Step-by-step explanation:
In this question, you want to make 10 liters 20% concentration solution by mixing 5% and 40% concentration. There should be multiple answers to this question. Assuming that the total volume of 5% and 40% solution equal to 10L(no solution wasted), then you can determine the volume of solution needed. The formula should be:
To multiply these parenthesis, you distribute
w*w=w^2
w*2=2w
-8*w=-8w
-8*2=-16
Then you add all these together for the answer:
w^2+2w-8w-16
w^2-6w-16 (combine like terms)
