Answer:
74
Step-by-step explanation:
2x+x+4=115 (ext ∠)
3x=111
x=37
∠MNO=2(37)
            =74°
 
        
                    
             
        
        
        
Answer:
w= -9/8 
Step-by-step explanation:
-1/3w -3/5 = 1/5w
+1/3w            +1/3 w
-3/5=1/5w+1/3w
Make common denominators to combine like terms of the right
-3/5=1/5w+1/3w
          *3       *5
-3/5=3/15w+5/15w
-3/5=8/15w
multiply both sides by the reciprocal of 8/15 which is 15/8
-3/5*15/8=8/15w*15/8
 *
* ----> cross reduce 5 in the denominator becomes 1 and 15 in the numerator becomes 3
 ----> cross reduce 5 in the denominator becomes 1 and 15 in the numerator becomes 3
 *
* -----> now multiply across
 -----> now multiply across
w= -9/8 
 
        
                    
             
        
        
        
We have:  x ×   ÷
 ÷  = x ×
 = x ×   ×
  ×   =  x ×
 =  x ×  = x ÷
 = x ÷

Answer: 68
Step-by-step explanation:
range=47 lowest score = 21 let highest score =x
Range=highest score - lowest score
47 = x - 21
x = 47 + 21
x = 68
Therefore the highest score is 68
