I think that the answer is four because it makes much more sense but five is not greater than five or less than five so I don’t know. Try four though sorry if it’s wrong though.
The equation should look like :
[H+] = (1-a)(x) + (a)(y)
Where:
5.8 = -log [H+]
5.0 = -log x
6.9 = -log y
(1-a) = proportion of x
<span>a = proportion of y
so calculating a will give you the result of how many ounces are required</span>
Can you please state the questions / problems or attach the image with the questions / problems so that we can answer it for you.

a: the slope is 2.5 and it means '<u>ammount of the rain is 2.5 mm. per hour</u>'.
2) the slope of the line is '<u>2.5</u>'
3) this means that '<u>2.5</u>' mm. of the rain falls every '<u>1</u>' hour.
