Answer: B
Step-by-step explanation:
Because your X values don't repeat
N+d=47
5n+10d=295
divide 2nd by 5
n+2d=59
we have
n+d=47
n+2d=59
eliminate n
multiply first equaton by -1 and add to other equaton
-n-d=-47
<u>n+2d=59 +</u>
0n+1d=12
d=12
sub back
n+d=47
n+12=47
minus 12 both sides
n=35
35 nickles
