On edgunity I got it right
D because you have to add -1 to -11 so -12 divided by 3 is -4
GI (make sure you put a line horizontal across the GI to label that you are mentioning a line segment)
We can write an equation in terms of n, the amount of nickels:
25(3n+3)+10(n+1)+5n=265.
Thus:
90n+85=265
Subtracting 85, we have:
90n=180
Therefore, n=2. As such, Danielle has 2 nickels, 3 dimes, and 9 quarters.
