Answer:

Step-by-step explanation:

.03(50) + 0x = (50-x).05 How much 3% salt much be added to zero percent salt to create a mixture that is 5 percent salt.

3(50) = (50 - x)5 I multiplied through by 100 to clear the decimals

150 = 250 - 5x Distribute the 5

-100 = -5x Subtract 100 from both sides of the equation

20 = x divide both sides by -5

solution:

$x^{2}+12x-7=0\\add 7 to both side of the equation\\x^{2}-12x=7\\to creat a trinomial square on the left side of the equation.\\find a value that is equal to the square of b and the cofficent of x.\\(\frac{b}{2})^2=(-6)^2\\add the term to each side of the equation\\x^2-12x+(-6)^2=7+(-6)\\x^2-12x+36=43\\(x-6)^2=43\\solve the equation for x.\\$ $take the square root of each side of the equation to the set up the solution x,\\(x-6)^2.\frac{1}{2}=\pm \sqrt{43}\\x-6=\pm \sqrt{43}\\x=6\pm \sqrt{43}$
