Answer:
Solution A = 2100
Solution B = 700
Step-by-step explanation:
Given that:
Let :
Millimeter of solution A = a
Millimeter of solution B = b
% alcohol, solution A =. 20% = 0.2
% alcohol solution B, = 14% = 0.14
Resulting millimeter of. Alcohol = 518
a = 3b - - - (1)
0.2a + 0.14b = 518 - - - - (2)
Put a = 3b in (2)
0.2(3b) + 0.14b = 518
0.6b + 0.14b = 518
0.74b = 518
b = 518 / 0.74
b = 700
a = 3b
a = 3(700)
a = 2100
Answer:
b<-21
Step-by-step explanation:
1/3b+1<-6
1/3b<-7
*3 *3
b<-21
A
I believe that I am correct
All you are basically doing is making ratios.
Basketball to football would be 5 to 11 or 5:11 or 5/11.
What you do is in the order you said it (basketball to football) you find that info and make it a ratio. A ratio must be simplified and can be written 3 ways, as shown above.
Hockey to lacrosse would be 6 to 10 and simplified would be 3 to 5.
Try doing 3 and 4 and 5 on your own to help you understand it more:) if you have any questions tell me.
