Answer:
Step-by-step explanation:So to find it you need to eliminate either x or y. 2x-5y=10 over 4x-10y=20. In order to get y to eliminate you need one equation to have a positive 10y and a negetive 10y. So you multiply both sides of the first equation by negetive 2 so it is now, -4x+10y=-20. Notice how all the numbers in both equations are opposite this gives us ims infinitaly many sollutions. So it is not A. Or b it will do the same thing. The answer is either D or C hope this helps

Answer:
$51.70
Step-by-step explanation:
I don't know how to explain it actually so I am just going to do this...
y= 0.1(x + 20) +7
y=0.1x + 2 + 7
y=0.1x +9
y=0.1(427)+9
y=42.7+9
y=51.7
So, maybe the answer is $51.70.
