The ratio of sediment yield of a drainage basin to the total amount of sediment moved by sheet erosion and channel <span>erosion.</span>
To find the answer set up an equation:

Using this set up we can cross our units of pages since they are on opposite side of the proportion, leaving us with the desired units of hours.
Then divide 400 by 65 which will give us our answer: 6.15 or about 6 hours for Jamie to finish her reading.
24=N is the correct answer
The answer is C-2x because you can substitute a number between -1 and 0 for x, so for example .5, and try out all the choices with .5. Ultimately you get 2(.5) as the largest number, so the answer is C.
