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

7/8 is closest to 1 and 4/9 is closest to 0
To solve for V:
p=vm Divide m from v to get it away from v
p/m=v
v=p/m V equals p divide by m to get the momentum.
each rose is $5 bc 90/18 is 5
Answer:
