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
Yes the treasury can determine whether the gold bar is
really weighing 500 ounces.
We can use the equation:
7 x + 11 y = 500
where x is the amount of the 7 ounce weights while y is
the amount of 11 ounce weights.
We know that x and y should be whole numbers therefore
this is solved through trial and error.
By trial and error I got:
x = 7 and y = 41
<span>
So that;</span>
7 * 7 + 11 * 41 = 500
49 + 451 = 500
500 = 500
<span>Hence they can use 41 11-ounce weights and 7 7-ounce
weights to test</span>
It's D. The curve intersects the y-axis at (0,10).
