The quantity of pure antifreeze that must be added to 2 quarts of a 20% antifreeze solution to obtain a 60% antifreeze solution 2 quarts
How to solve equation?
- x = quarts of 100% antifreeze
You have 2 quarts of 20% antifreeze.
(100%)x + (20%)2 = 60%(x + 2)
100x + 40 = 60(x + 2)
100x + 40 = 60x + 120
100x - 60x = 120 - 40
40x = 80
x = 80/40
x = 2 quarts

Answer:
x = 3 + 7i or x = 3 - 7i; a = 3; b = 7
Step-by-step explanation:
x^2 - 6x = -58
We complete the square by adding the square of half of the coefficient of the x-term to both sides.
x^2 - 6x + 9 = -58 + 9
(x - 3)^2 = -49

x = 3 + 7i or x = 3 - 7i
a = 3; b = 7
