A total of 22 dimes and nickels have a value of $1.90. If d represents the number of dimes and n represents the number of nickels, which system of equations models this situation? A.
d + n = 1.9
0.1d + 0.05n = 22
B.
d + n = 22
0.1d + 0.05n = 1.9
C.
d + n = 1.9
0.1d + 0.5n = 22
D.
d + n = 22
0.1d + 0.5n = 1.9

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
