Answer:
Quincy read 9 books.
Step-by-step explanation:
Work backwards. Samantha read three less books than Teresa (11-3=8). Ralph read half as many books as Samantha (8/2 = 4). Quincy read five more books than Ralph (4 + 5 = 9).
 
        
             
        
        
        
The answer would be 1/3 up 1 over 3.
        
                    
             
        
        
        
The formula for multiplying exponents are such below.
(b^m)^n = b^mn
b^m/b^n=b^(m-n)
b^m x b^n=b^(m+n)

Answer:
105
Step-by-step explanation:
The interior angle for R is supplementary to the 155 degree angle
(they add to 180)
180-155=25
The sum of the interior angles of a triangle is always 180
180-50-25= 105
