HELP PLS A carnival charges $2.50 per ride after an entrance fee.You paid a total of $22.50 after 6 rides.Find the total cost fo
Finger [1]
The cost of the entrance would be 7.5$, because 2.50$ x 6 equals 15.

Let’s multiply 6 x 2 to get twelve, and if six rides are 15$, that would be 30$ for twelve rides. But we still have three more.

2.50 x 3 would be 7.5$, and if we add that to 30$, we would get 37.5$.

With entry fee though, we would add 37.5$ to
7.5$, and so it would be 45$ on the dot.

Your answer would be 37.5$ without entry fee, and 45$ with entry fee.

If this helped.. please do me a favor and mark this as the Brainliest! :))

Naddik [55]

Answer:

4 {x}^{2}  + 2xy - 2 {y}^{2}

Step-by-step explanation:

(x + y)(x - 5y) +  {3(x + y)}^{2}  \\ x(x - 5y) + y(x - 5y) + 3(x + y)(x + y) \\  {x}^{2}  - 5xy + xy - 5 {y}^{2}  + (3x + 3y)(x + y) \\  {x}^{2}  - 4xy - 5 {y}^{2}  + 3x(x + y) + 3y(x + y) \\  {x}^{2}  - 4xy - 5 {y}^{2}  + 3 {x}^{2}  + 3xy + 3xy + 3 {y}^{2}  \\  {x}^{2}  - 4xy - 5 {y}^{2}  + 3 {x}^{2}  + 6xy + 3 {y}^{2}  \\  {x}^{2}  + 3 {x}^{2}  - 4xy + 6xy - 5 {y}^{2}  + 3 {y}^{2}  \\ 4 {x}^{2}  + 2xy - 2 {y}^{2}
