I believe by the first equation they are referring two a representation of the total amount of money made up by the two types of coins. I found this to be 0.05x + 0.10y = 3.50
In my work I solved for the amount of each coin- I assume this is what the final step of your problem entails. If you need any help understanding/ I misinterpreted something please feel free to comment and ask :)
#5c coins or x= 36
#10c coins or y= 17
Answer:
20
Step-by-step explanation:
I think that the answer would be -3/5 because when you turn 1/3 into 2/6, you can do 2/6 - 5/6 which is -3/6 or -1/2. To divide, you would flip the reciprocal and do 6/5 multiplied by -1/2, which is -6/10, or -3/5.
(2*3+x^2)+3(234x^2)
=6+x^2+702x^2
=703x^2+6
