Answer:

D. 0.925x + 0.88y = 0.91(x + y)  

Step-by-step explanation:

The important point to remember is that the total mass of pure silver is the same on each side of the equation.

0.925x = mass of pure silver in first alloy

0.88  y = mass of pure silver in second alloy

The final alloy has a mass of (x + y) g and is 91 % pure silver, so

0.925x + 0.88y = 0.91(x + y)

8x=4x^2-1 <br>solve by completing the square
Klio2033 [76]
Get the x terms by themselves on one side and a constant on the other side of the equal sign...

4x^2-8x=1  make the leading coefficient equal to one...

x^2-2x=1/4  now halve the linear coefficient, -2 in this case, square it, and add that value to both sides of the equation...-2/2=-1, -1^2=1 so

x^2-2x+1=1+1/4

x^2-2x+1=5/4  now the left side is a perfect square...

(x-1)^2=5/4  take the square root of both sides...

x-1=±√(5/4)  add 1 to both sides

x=1±√(5/4)
