The answer is 2.8. or around there
15/x=75/100
15/x=3/4
times 4x both sides
4*15=3x
60=3x
divide both sides by 3
20=x
Let

. Then

and

are two fundamental, linearly independent solution that satisfy


Note that

, so that

. Adding

doesn't change this, since

.
So if we suppose

then substituting

would give

To make sure everything cancels out, multiply the second degree term by

, so that

Then if

, we get

as desired. So one possible ODE would be

(See "Euler-Cauchy equation" for more info)
Answer:
3.75 of blue mixed with 12.5 of white is the correct answer
Step-by-step explanation:
We know the blue and white paints are a 1.5 : 5 ratio, and if we have a total of 16.25 by 1.5 by 5.
1.5 * 2.5 = 3.75
------------------------
5 * 2.5 = 12.5
SO blue is 3.75 and white is 12.5
