5x+7y=29.50 and 9x+2y=16 can be used to determine the cost of each game and each ride.
Variable x is the cost of one game and variable y is the cost of one ride.
Step-by-step explanation:
Let,
Cost of one game = x
Cost of one ride = y
Ayden played 5 games and went on 7 rides and spent a total of $29.50.
5x+7y=29.50 Eqn 1
Sophie played 9 games and went on 2 rides and spent a total of $16.
9x+2y=16 Eqn 2
5x+7y=29.50 and 9x+2y=16 can be used to determine the cost of each game and each ride.
Variable x is the cost of one game and variable y is the cost of one ride.

Answer:
455 possible ways
Step-by-step explanation:
We are told that 15 women are trying out for parts in a production of snow white.
Now, we want to find the number of ways that 3 women can be selected to play.
This is simply a combination question.
Thus;
Number of ways = C(15, 3) = 15!/((15 - 3)!(3!) = 15!/(12! × 3!) = (15 × 14 × 13 × 12!)(12! × 3 × 2 × 1)
12! will cancel out to give;
(15 × 14 × 13)/6 = 455
Answer:
the first equation, make the y as the subject. y = 3 + 5x, then substitute y in the second equation and you will get the value of x. then, substitute the x in the first equation (y = 3 + 5x)
