We can tell that the whole L shaped angle is 90 degrees because it has the little box in the corner. Now, the 90 degree angle is split into two parts with that line coming from the box. Those two parts of the whole 90 degree angle add up to 90 degrees.
90 = 4v + 2 + 9v - 3
Now, let's solve for v. Combine like terms.
90 = 13v - 1
Add 1 to both sides.
91 = 13v
Divide both sides by 13
7 = v
a divided by 6
if a = 48 just replace that value for a so now you have 48 divided by 6 which equals 8
Answer:
Step-by-step explanation:
Let us assume there are n people in the group. If possible let each have different number of friends.
Number of friends can vary from 0 to n-1 only since no one is a friend of him- or herself, and friendship is symmetrical—if x is a friend of y then y is a friend of x.)
Now n people have friends as 0,1,2...n-1 such that each has distinct number of friends.
But say if A has 0 friends, it means A has no friend,
but there is one B who has n-1 friends i.e. all the others in the party are friends to him including A
This is a contradiction. So it follows in any group of people, two of them have the same number of friends in the group.
We are given two stores to select and this stores are located in the same distance but of different cities of different tax rates. One city has a tax rate of 7% and the other city has a 8.5%. in order to save, you need to choose a lower tax rate which is 7%. This saves you 1.5% as compared 8.5% of other city
