Answer: x=4
Step-by-step explanation: Add 3 to both sides,  Divide both sides by 22
 
        
                    
             
        
        
        
Answer:
A = 157 in^2 
Step-by-step explanation:
First, we need to get the radius, we can do this by dividing our given diameter by 2. 
20/2 = 10 
Now, we have our radius of 10 inches. 
Formula for Area of a Semi Circle: (1/2)(pi(r^2)
Input values. 
(1/2)(3.14(10^2)
Solve. 
(1/2)(3.14(100)
(1/2)(314)
1/2(314) = 157 
Finally, we have our result which is 157 inches^2. 
 
        
                    
             
        
        
        
Answer:
(6,41)
x=6
y=41
Step-by-step explanation:
I did it algebraically to solve for x and y, and I also graphed both of them and found the point where they intersect. It’s in the image below.
Hope this helps! :)
 
        
             
        
        
        
Factor dem groups
find greatest common factor
24=2*2*2*3
40=2*2*2*5
common is 2*2*2=8
answer is 8 groups
