Answer:
48: 24
Step-by-step explanation:
divide.
<span>9x-y=5
rewriting the eqn in the form y = mx+b we get
y = 9x- 5
slope = 9</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

I have no idea what is is but try 4 or 1,If not you should go on cymath
The answer is 2.42
cuz i did the math and stuff
