9. -1,07, 1/2. 3........it is all I could see
10. -V25= -5
-5, -4,3, 0, V15, 4,2
        
             
        
        
        
So, what is the case in which he uses the least coins? can he use 1 coin? no, there isn't a 35 cent coin. can he use 2 coins? yes! he can use 25+10 cent coins!
now, the largest number of coins means the coins of the smallest value: so using only 5 cent coins. How many would this be? 
we have to divide: 
35/5=7
so we would use 7 coins. 
And the difference is 5: 7-2 is 5. 
        
             
        
        
        
Answer:
see the explanation
Step-by-step explanation:
we know that
<u><em>Alternate Exterior Angles</em></u> are created where a transversal crosses two lines.  Notice that the two alternate exterior angles are equal in measure if the two lines are parallel
In this problem
 ----> by alternate exterior angles
 ----> by alternate exterior angles
One way to verify alternate exterior angles is to see that they are the vertical angles of the alternate interior angles
 
        
             
        
        
        
First you add 11+4 which equals 15 then you add 15+9 which equals 24. So Sandra sees 24 flags
