ANSWER
The set of the intersection of {
} and {
} is
{
}
EXPLANATION
Let 
{}
and
{}.
The intersection of the two sets are the elements that are in both set A and set B.
The elements that are common to both sets are 2 and 5. So, we write;
{}
Therefore the correct answer is C

The solution is in the attached file below
Answer:
it will take her 
minutes more to walk down to Raj's House
Step-by-step explanation:
It took Sheldon 
minutes to walk to Raj's house
It also took Sheldon 
minutes to use the bus.
To get the time difference between the two transport mechanisms, we subtract their different time durations.
This will be
We can convert this to Mixed fractions as shown minutes.
Therefore, it will take her minutes more to walk down to Raj's House
It would be 130/7+4 because 130 is the total divide it by how many she does and add how many she already has
Ok
the sets are
natural numbers (or counting numbers), this is like 1,2,3,4,5 etc
whole numbers, this is including 0, so 0,1,2,3,4,5,6 etc
integers, this includes the previoius set and negatives, so -3,-2,-1,0,1,2,3,4,5 etc
rational numbers, this is the set of numbers that can be written in form a/b where b≠0, so all integers can be written like this, like example -3=-3/1, so -7/9 belongs here
-7/9 goes in the rational set
