Answer: Comparison Postulate
This is the idea that exactly one statement shown below is true
a > b
a = b
a < b
So if you compare two numbers, then either the left value is larger, the left is smaller, or the the left is the same as the value on the right.
 
        
             
        
        
        
So if ever looking for % of, and you have a calculator a very simple way of doing it is taking your actual amount ($74.00) and multiplying it by 0.26
0.26, mathematically is like saying 26% of
The answer is 19.24
You'll notice if you type 74 x 0.50 (which is 50%) you will get 37 -- exactly half of  74
        
             
        
        
        
First one is graph C second one is graph B third is graph D
        
             
        
        
        
You could use the Pythagorean theorem which is a squared +b squared= c squared
you know a and c
a=24
c=25
24 squared + x squared = 25 squared
576+x squared =625
subtract 576 from both sides
x squared = 49
square root x and 49
x=7
C is the answer
