Answer:
c
Step-by-step explanation:
because it has 3 parts. tri.
576.54
is going to be the answer
Check the angle. If it they are less than 90°<span> , so they will result in acute angles. </span>
10d+5n=220
divide both sides by 5
2d+n=44
d=13+n
sub 13+n for d in other equatin
2(13+n)+n=44
26+2n+n=44
26+3n=44
minus 26 both sides
3n=18
divide both sides by 3
n=6
sub back
d=13+n
d=13+6
d=19
19 dimes
6 nickles
D) a numerical expressions
I hope it's help you...
