80 dimes is equal to 800 cents
Answer:
DE/DF, D
Step-by-step explanation:
no explanation, it's a law
Cx/d=b-f
Cx=(b-f)d
X=[(b-f)d]/c
X+2y=23
X=-2y +23
Plug this in for x in the second equation
5(-2y + 23) + 10y = 55
-10y + 115 + 10y = 55
The -10y + 10y cancel out, so there is no solution
Hope this helps!
