Answer:

Step-by-step explanation:
Step one
Given data
On  Monday, Jesse drank 3/4 of liter of water before jogging
and drank 3/5 of liter after jogging
In all, Jesse drank 3/4 and 3/5 liters of water
= 3/4+3/5
the lcm is 20
=15+12/20
=27/20
in mixed numbers(i.e a whole and a fraction together we have) we have

 
        
             
        
        
        
4.  When reading the stem and leaf plot the only values that fall between the range of  40 < x <60  is the 4 values of 45.  They are located at the tail end of the 4 stem after the zeros. The 40s and 60s are not counted because it is not mentioned equal to 40 or 60.
        
                    
             
        
        
        
16.22 divided by 2 = your answer. (8.11)
        
                    
             
        
        
        
90 = 20 + 70.....GCF of 20 and 70 is 10
90 = 10(2 + 7) <==
can u write another expression using a different common factor...yes
90 = 20 + 70.....common factor is 5
90 = 5(4 + 14) <==
