Answer:
x = 7, y = 28
Step-by-step explanation:
We're given that ABCD is a rectangle, so we know that all sides opposite from each others are equal in length. This also means that each part of the criss-cross-X thing inside the rectangle are equal in length to each others as well. (AE = BE = DE = CE).
AC = 100 from the given picture, which means half of that from AE would be 50. Since DE is the same length as AE, we can set x²+1 = 50 and solve for x. We get x = 7.
To solve for y, we know that opposite sides of a rectangle are of the same length. So AD = BC.
The question already gave us the equation for those sides so we just need to set them equal to each other.
2y + 5 = 3y - 23
sovle for it and you get y = 28.

Answer:
C. Gas Station A sells gasoline at a lower rate. Its price is $3.05 per gallon
Step-by-step explanation:
To answer this, all you need to do is first figure out how much per gallon each of the gas stations offer.
Because Gas station B is practically given to you by the equation, I'll show you how to interpret it:
p = $3.08g
p is the price
g is the gallon
So the price you will pay will be $3.08 times the number of gallons. This means that 1 gallon, if you substitute it will be $3.08.
This would eliminate options A and B.
Now to figure out how much Gas station A charges, just choose one of the prices. All we need to do is to divide the price given by the number of gallons:
So Gas station A is lower than Gas station B.
