What is 9 inches? Is 9 inches the diameter? Or the radius? What?
The equation for circumference is pi x diameter.
So assuming the 9 inches is the diameter:
Pi x 9 = 28.2743339
Circumference = 28.274 (3 d.p.)
        
             
        
        
        
Answer:
$106.00
Step-by-step explanation:
origional amount = x
x + 26 + x + 26 = 264
2x + 52 = 264
2x = 264 - 52
2x = 212
x = 212/2
   = 106
Hope this helps you! Have an amazing day :)
 
        
             
        
        
        
Judging by the problem you want me to use substitute method 
Since why equals 1/2x-1 you
Do 2(1/2x-1)= x-2
You multiple by 2 cause there’s two on the top for y. So the problem is now 4x-x-2
Combine like terms 3x+2=14
Subtract two on both sides 
3x=12
X=4
Go back to the bottom since u know x now do y= 4.1/2-1 solve to get one 
Y=1 so your answer is (4,1)
        
             
        
        
        
Answer:
g(r) = 18 
Step-by-step explanation:
 Substitute 10 into r 
g(10) = 2( (10) -1) 
         = 2(9)
         = 18 
 
        
             
        
        
        
It’s D 
16/4 is 4 no more no less
