Answer:
Age of q = 42 years
Step-by-step explanation:
Ratio of the ages of three people p, q and r is 6 : 7 : 11
Sum of the ages of p and r = 102 years
Age of p = 
                = 36 years
Therefore, age of r = 102 - 36 
                                 = 66 years
Since, ratio of p and q = 6 : 7
Therefore, 

q = 
q = 42 years

Answer:
6.8
Step-by-step explanation:
(2/5)*17
=6.8
 
        
                    
             
        
        
        
3x+y=9 ....(1)
3x-5y=15. ......(2)
-[3x-5y=15]
=> 3x+ y = 9
-3x+5y=-15
..........................
0 +6y=-6
so,y=-1
3x+(-1)=9
3x=10
x=10/3
        
                    
             
        
        
        
The vertex is (-5, 5) and the parabola opens downward. The vertex form equation is
.. y = -(x +5)^2 +5
