Answer:
42%
Step-by-step explanation:
x is for the volume of the container
the amount filled in the first container=0.30x
the volume of the first container + 50% of the second=(x+x*50%)=1.5 x
the amount of acid in the second container= 1.5x * 50%=0.75x
total amount of acid in the third one =0.3x+0.75x=1.05x
total solution : x+1.5x=2.5x
percentage=1.05x/2.5x= 0.42 or 42%
Answer: y = 15x + 32
Step-by-step explanation: 32 is the start up fee meaning that it's the y-intercept because even at 0 months, you have to pay $32. The $15 is the slope because that's what you pay per month... so it's the amount of months (x) multiplied by the dollar amount ($15).

To find average you add all of the listed numbers, (2, 3, 1, 4, 5, 2, 3, 4, 3) which is 27. You then divide 27 by the amount of listed numbers, which is 9. 27 divided by 9 is 3. There for the average amount of strokes it takes to hit the ball into the hole of each green is 3.
