The empty set, if you are referring to names of days of the week.
( )
an empty set
First of all, there are many different ways to express 3 in set builder notation, to be more precise, there are many different ways to express the set containing 3 as its only element. Here are a few ways {x∈R | x=3} or {x∈N | 2<x<4} or even just {3}
if you meant how many week days then x = x * 5 if you meant how many days alltogether then x = x * 7
Coordinate Plane
How many hours are in ONE day? 24. It is a proportion! Set it up like this: 1/24 = 2.7/x Then you cross multiply. 1 times x is just x. 24 times 2.7 is 64.8. There are 64 hours and 8 minutes in 2.7 days. :)

A_{x\x are set of days in a week}
The union of two sets, X and Y, is the set containing all the elements that are either in X or in Y or in both. Duplicate entries are usually removed.
{x| x is the name of day of week}
In a set of 17 years including 4 leap years, there are a total of (13 x 365) + (4 x 366) = 6209 days. In a set of 17 years including 5 leap years, there are a total of (12 x 365) + (5 x 366) = 6210 days.
The unit set of x is the set whose sole member is x. The unit set is to be distinguished from its member: for example, the unit set of the set of days of the week has one member, but that member is itself a set that has seven members.

As there are 7 days in a week, x weeks will equal 7x days.So: x weeks + x days = 7x days + x days = 8x days.
A relation is any set of ordered pairs. A relation can be represented by: - an x-y graph with a dot for each ordered pair. - in set notation e.g. {(1,2), (2, 4), (3, 6)} - an arrow diagram. On the left is an oval containing the elements of the domain (x-values). On the right is an oval containing the elememts of the range ( y-values). For each ordered pair, an arrow is drawn from the x-value to y-value.
The only country containing an x is Mexico.

if you meant how many week days then x = x * 5 if you meant how many days alltogether then x = x * 7
Set up a proportion: 1 Day: 24 Hours is x Days: 92 Hours Multiply the left side of the first half by the right side of the second half, and vice versa. This gives: 24x=92 x=92/24 x= 3 and 5/6 days or 3.833333333333 days
