The answer is C: first add 2 both sides then divide both sides by -5.
        
             
        
        
        
Answer:
$13.50
Step-by-step explanation:
if the total is $31.50, it is both the blouse and the skirt together, so uf you take away the blouse from the total ($31.50 - $18) then yiu are keft with the price of the skirt
 
        
             
        
        
        
Equation : (7x-4)+(3x-3)+(x) = 180 
In the equation the sum of the internal angle in the triangle is 180 degrees. Use this equation to figure the sum of angle in any quadrilateral 180*(number of sides-2) 
Solve the equation 
Put all similar variable on one side 
7x+3x+x-4-3=180
11x-7=180 
11x=180+7 
11x=187 
x = 187/11 
x = 17 
Now find the angles by plugging in x
Angle F (7*17-4) = 115 degrees 
Angle G (x) = 17 degrees 
Angle E (3*17-3) = 48 degrees 
If you add 115+48+17 you will get a sum of 180 this shows your answer is right 
Angle F = 115 
Angle G = 17 
Angle E = 48
