Answer: There are 7,677 streets named as " First Street" and 7, 189 streets named as "Main Street" .
Step-by-step explanation:
Let x be the number of streets named as First Street .
y be the number of streets named as Main Street.
AS per the given information, we have the following system of equations :
Substitute the value of x from (2) in (1) , we get
Put value of y in (2), we get
Hence , there are 7,677 streets named as " First Street" and 7, 189 streets named as "Main Street" .
Answer:

Step-by-step explanation:
Since repetition isn't allowed, there would be choices for the first donut, choices for the second donut, and choices for the third donut. If the order in which donuts are placed in the bag matters, there would be unique ways to choose a bag of these donuts.
In practice, donuts in the bag are mixed, and the ordering of donuts doesn't matter. The same way of counting would then count every possible mix of three donuts type times.
For example, if a bag includes donut of type , , and , the count would include the following arrangements:
Thus, when the order of donuts in the bag doesn't matter, it would be necessary to divide the count by to find the actual number of donut combinations:
.
Using combinatorics notations, the answer to this question is the same as the number of ways to choose an unordered set of objects from a set of distinct objects:
