2 step equations are equations that require 2 steps to solve it.
For example, 2x + 5 = 3x + 6
To solve for x, we must isolate it.
First subtract 2x on both sides, which is ONE step.
2x + 5 = 3x + 6
-2x -2x
5 = x + 6
The we must subtract 6 from both sides of the equation, which makes is the second step.
5 = x + 6
-6 -6
-1 = x
-1 would be the answer and we only used 2 steps to solve it.

Answer: commutative property
Step-by-step explanation:
basically the commutative property of multiplication says that it doesn't matter what order you multiply the numbers, it will all equal the same.
the rule is "ab = ba"; in numbers, this means 6×3 = 3×6
Answer:
The probability that a student arriving at the ATM will have to wait is 67%.
Step-by-step explanation:
This can be solved using the queueing theory models.
We have a mean rate of arrival of:
We have a service rate of:
The probability that a student arriving at the ATM will have to wait is equal to 1 minus the probability of having 0 students in the ATM (idle ATM).
Then, the probability that a student arriving at the ATM will have to wait is equal to the utilization rate of the ATM.
The last can be calculated as:
Then, the probability that a student arriving at the ATM will have to wait is 67%.
