Divide both sides of the equation by 0.1 which leaves you with
n = 89.9/0.1 = 899
 
        
                    
             
        
        
        
Answer: 56
Step-by-step explanation:
 
        
                    
             
        
        
        
The answer is 14.5 because :
2 times 2?5 = 5 so the denominator must have the same done, so 7.5 x 2.5 is 17.5. Subtract 3 from 7.5 and you get 14 .5 . So, m+ 14.5

 The relation is not a function. 
Step-by-step explanation:
 By definition, a relation is a function if each input value has only one output value.
 Given the relation:
 (4,23)
 (3,-2)
 (-6,5)
 (4,6)
 The domain is the set of the x-coordinates of each ordered pair (You do not need to write 4 twice):
  {
{ }
}
 The range is the set of the y-coordinates of each ordered pair :
   {
{ }
}
 Since the input value 4 has two different output values (23 and 6), the relation is not a function.
 
        
                    
             
        
        
        
Answer:
x = 6
Step-by-step explanation:
7 x = 56-14
7 x = 42
7 x/7 to remain with x only = 42
then x = 6
