Answer:
angle 1:    72.5°
angle 2:   107.5°
Step-by-step explanation:
x + y = 180
x - y = 35         ===>      x = 35 + y
Substitution to find angle y:
   x + y = 180
   (35 + y) + y = 180
   35 + 2y = 180
   2y = 145
   y = 72.5
Substitution to find angle x:
   x = 35 + y
   x = 35 + (72.5)
   x = 107.5
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
you will save $4 per person 
30x5 = 150
 150-130= 20
20/5= 4
 
        
             
        
        
        
Answer:
The answer is square root of 16. 2 to the power of 3 over 2 is 4 and the square root of 16 is 4.
 
        
             
        
        
        
Y = 6x - 6  therefore   y - 6x = -6
y - 6x = 5 
so:
-6 ≠ 5
There is no solution to this system.
