Hi there!
So, 2.25x would represet the total amount of money spent for all the games.
2.25x + 2.50 = 9.25 would be the equation to represent this scenario.
Now to solve: Our goal is the get x alone. Subtract 2.50 (the price of the shoes) from both sides. 9.25 - 2.50 = 6.75.
We are now left with 2.25x = 6.75.
Finally, we divide both sides of the equation by 2.25, which leaves us with x = 3.
So you can bowl for a total of 3 games.
I hope I helped!
Answer:

Step-by-step explanation:
- The lengths of the sides of a 30-60-90 triangle are in the ratio 1:2:√3.
- The lengths of the sides of a 45-45-90 triangle are in the ratio 1 : 1 : √2
- We can get the length of the longest side of the bottom triangle is 9×2÷√3 =

- And based on the theory shown on the 2nd step, we can get x (the length of the longest side of the upper triangle) is
x√2
