2. 9a +4c=43
a+c=7
The total tickets for adults and children = 7 (a+c =7)       7 people in all
price for adult = $9  (9a)   Price per child =$4 (4c) 
total price =$ 43
   9a +7c = 43
 
        
             
        
        
        
Answer:
Step-by-step explanation:
The general equation of the circle is:
(x-h)²+(y-k)²=r²
(h, k)=(-3,-5)  are the coordinates of the center of the circle.
r=6  is the radius
The equation of the circle is:
(x+3)²+(y+5)² = 36

Answer:
   C.  11
Step-by-step explanation:
Substituting, we have ...
   8{80, 19, 11} ?= 88
   {640, 152, 88} ?= 88
The value from the set that makes the equation true is x = 11.
_____
<em>Alternate methods of solution (other than substitution)</em>
It can be easier to make use of your knowledge of factoring:
   8x = 8·11
   x = 11
Or to make use of your knowledge of numbers (place value):
   8·10 = 80
so x will not be very different from 10.
