Answer:
The number of different schedules possible is given by:
In which n is the number of European cities that Betty would eventually like to visit.
Step-by-step explanation:
The order in which the cities are visited is important, for example, visiting Paris on Monday and London on Tuesday is a different schedule than London on Monday and Paris on Tuesday. This means that the permutations formula is used to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
She wants to visit n cities on 3 days:
So the number of different schedules possible is given by:
In which n is the number of European cities that Betty would eventually like to visit.

Answer:
2 = x
Step-by-step explanation:
1: Add 5x to both sides ( to get rid of 5x, we are adding it because it is negative )
3 - 5x + 5x = -9 + x + 5x
3 = 6x -9
2: Add 9 to both sides ( to get rid of the 9, we are adding it because it is negative )
3 + 9 = 6x - 9 + 9
12 = 6x
3: Divide both sides by 6 to get x by itself
12/6 = 6x/6
2 = x
- Note: the reason why we make changes to both sides is to keep the statement true ( equal ) -
