>>...Brian has no more than 16 coins...<< 

That says if you add the number of nickels (x) to the number of
dimes (y) you get a number either less than 16 or equal to 16:

x + y < 16

>>...There are at least four times as many nickels as there are dimes...<< 


That says the number of nickels (x) is greater than or equal to 4
times the number of dimes (y).

x > 4y

>>...Which of the following is a system of inequalities that describes this situation?...<<


That's this system:

x + y < 16
x > 4y
