How many quarts of pure antifreeze must be added to 2 quarts of a 20% antifreeze solution to obtain a 60% antifreeze solution?
blsea [12.9K]

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

Enter the correct answer in the box. What are the solutions of this quadratic equation?
IrinaVladis [17]

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 = \pm 7i

x = 3 + 7i   or   x = 3 - 7i

a = 3; b = 7
