Answer:
4.52 x 10^-7
Step-by-step explanation:
you have a very small number (numbers to right of decimal) so you're exponent will be negative.
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
1-3n=-9+n+2 ---> -3n-n=-1+-9+2 --> -4n=-8 ---> n=2
 
        
             
        
        
        
So, 
Here we have the following algebraic expression:

The first term of this expression is -5x.
This term is clearly a variable term. The variable is x and its coefficient is -5.
 
        
             
        
        
        
        
Answer:
infinite solutions
Step-by-step explanation:
10 + 4x = 2(2x + 5)
