Suppose you add x liters of pure water to the 10 L of 25% acid solution. The new solution's volume is x + 10 L. Each L of pure water contributes no acid, while the starting solution contains 2.5 L of acid. So in the new solution, you end up with a concentration of (2.5 L)/(x + 10 L), and you want this concentration to be 10%. So we have

and so you would need to add 15 L of pure water to get the desired concentration of acid.
Answer:
13+2x=67 soooooo x = 27 so the video game is $27 and thats the equation
Step-by-step explanation:
Coin: 50%; 1/2 chance to get heads
dice: 17%; 1/6 chance to get 2
The slope is 4/3x.
Since the y-intercept is (0,-3), you go up and see that the next point is (1,1).
