Answer:
6x + 4 - 1/100 = 77.5 
Step-by-step explanation:
Inc shipping all shirts 77.49
Shirt individual cost = 12.25
We find the division first = 77.49-3.99 = 73.5  = 73 1/2
Then we divide 73.5 / 12.25 = 6
Then we have our equation
6x + 4 - 1/100 = 77.5
 
        
             
        
        
        
A
x=75°
B
We know that ∠EFG=∠ABF because they are corresponding angles.
We also know that ∠x+∠ABF=180, because angles along a straight line always equal 180:
x+105=180
x=75°
 
        
             
        
        
        
Answer:
ohh hiiii...................
 
        
                    
             
        
        
        
So all angles within a triangle should add up to 180, 102+31= 133 then subtract. 180-133=47
