Just draw a line at the midpoint and a salon also if this helps OK
Answer:
D. He should add between 2 cups and 3 cups of dirt.
Step-by-step explanation:
First we need to take the ratio of dirt to peat moss.
8 parts dirt : 3 parts peat moss.
Now we take the ratio and find the value of dirt.
8 : 3 = 
x : 1 = 

We now multiply both sides by 1.



So now we substitute x.
2.67 Cups Dirt : 1 Cup Peat Moss
Recall the Pythagorean identity,

So we have



But squaring any real number always gives a non-negative number, so there are no real solutions to this equation.
