real numbers are all numbers/points that exist at the variety line.real numbers may be divided into the following divisions:Rational numbers; any range which may be written within the form ofin which p and q are co-prime integer numbers , are called rational numbers. Irrational numbers ; all numbers which cannot be written as a simple fraction is referred to as irrational numbers.

Given two real numbers x and y . Let us consider $x < y$ .

According to the question their sum is 25.

$\therefore x+y=25$ .............(i)

The difference of the numbers is 13.

$\therefore x-y=13$ ...........(ii)

Now we have to solve the simultaneous equation:

adding equations (i) and (ii) we get:

$x+y=25\\\underline{x-y=13}\\\\2x=38\\or,x=19$

Substituting the value x=19 into equation (i) we get:

$x+y=25\\or,19+y=25\\or,y=25-19\\or,y=6$

Now let us find the product xy

$xy=19\times 6\\or,xy=114$

The product xy is 114 which is also a real number.

How many days did carol work at the restaurants during the 28 day period ?

Anarel [89]

$\bf \underset{\frac{1}{4}\textit{ of 28}}{\stackrel{\textit{at the Bookstore}}{\cfrac{1}{4}(28)}}\implies \cfrac{28}{4}\implies 7~\hfill \underset{\frac{1}{14}\textit{ of 28}}{\stackrel{\textit{did not work}}{\cfrac{1}{14}(28)}}\implies \cfrac{28}{14}\implies 2 \\\\\\ \stackrel{\textit{remaining days}}{28 - 7 - 2}\implies 28-9\implies \stackrel{\textit{at the Restaurant}}{19}$
