Answer:
The answer already exists in your question...
That is correct expansion
Answer: an average resulting from the multiplication of each component by a factor reflecting its importance.
Step-by-step explanation:
Let volume of 4% solution = x and of 14% be y
them x + y = 65........(1) also using the actual weights of salt:-
0.04x + 0.14y = 65*0.06 = 3.9
multiplying the above equation by -25 we have
-x - 3.5y = -97.5 adding this to equation (1)
--2.5y = -32.5
y= 13
and x = 65 - 13 = 52
so we need 13 mls of the 14%, and 52 mls of the 4% solution.
So first you would divide the 9 on both sides then 6 divided by 9 would be .6 repeating so m=.6 repeating.
4 miles because there are 5280 ft in one mile so if you were to multiply that by 4 you would get 21120 ft
