We have to check which of PEMDAS rules can be applied in this case. We have only ADDITION. In this case we can observe that addition is:
1. Associative

2. Commutative

3. has Additive property

Step-by-step explanation:
Your question isn't complete but I believe that you want to know the number of rides that Katie can take.
Based on the information in the question, we can form an equation. Let the number of rides that Katie can take be represented by x. Therefore,
12 + (1.25 × x) = 50
12 + 1.25x = 50
1.25x = 50 - 12
1.25x = 38
x = 38/1.25
x = 30.4
Therefore, Katie can take at most 30 rides.
Let's make the equation.
2(N+9)=6
Let's divide both sides by 2.
n+9=3
Now subtract 9 from both sides.
n=-6
So, the number is -6.
