Answer:
I think the answer is A! Hope this helps...
Step-by-step explanation:
Yes it does, the number of wheels is dependent on the number cars, and each number of wheels will only correspond to one number of cars.
There's two possible ways to find the answer to this. First you can find a common denominator to reduce both to. In this case, they can both reduce to a common denominator of 8. So 6/16 reduces to 3/8 and 30/80 also reduces to 3/8, so they are equal. The other way is to use a calculator and turn them into decimals by dividing the numerator by the denominator. They both come out to be .375. Once again they are equal. You can use whichever method is easier for you.
You FOIL (First, Outer, Inner, Last)
If you FOIL, you should get 2y^2 - 4y + 4y^2 - 8y +12y -24
Im pretty sure it would be 15.50+(5.00*x) hope i helped have a nice day
