So Maurice would have 2N nickels
Total number of coins is N + 2N + 9 = 3N + 9
Each nickel is 5 pennies
3N of nickels = 15N pennies
-----------
Their worth is 84 cents
15N + 9 = 84
15N = 75
N = 75/15 = 5
N = 5
This means Nina has 5 nickels.
Y = kx where k is a constant
27 = k*9
k = 27/9 = 3
required variation is y = 3x

3x^2y^2
Step-by-step explanation:
the gcf is 3x^2y^2 since it is the common factor in all of the terms
