Step-by-step explanation:
5x-12=3x+20
plus 12 both sides
5x=3x+32
-3x both sides 
2x=32
divide by 2 both sides
x=16

Answer:
 $ 3 left ashley money
 $ 1 left  jacks money
 $ 8 left ashley money
$ 4 left jacks money
Step-by-step explanation
3 pencils + 6 rulers = 12 - 9 = 3
5 pencils +  2 rulers = 8 - 7 = 1
 12 - 4 = 8
8 - 4 = 4
 
        
                    
             
        
        
        
This is a difference of squares, meaning that when you multiply the binomials it would be the front term squared minus the last term squared.
The front term squared = (3A) squared = 9A squared
The last term squared = (4B) squared = 16B squared
Final Answer: D. 9A squared - 16B squared
        
             
        
        
        
Answer:
if you look at carefully the left triangle has two same side. so left-angle of C is 180-130=50 degree 5x+5x+50=180 x=13 degree 
Step-by-step explanation:
for right triangle again one angle is 50 degree and other is 6*13-(3)=75 degree so 75+50+(10y+5)=180 degree y=5 degree
