Answer:

Step-by-step explanation:
Here, the given expression is:
 
Now, by logarithm rules, we know 
 if  
, then x =
Comparing here, b = 10  and  z = 2
⇒ y  =   
or, 
 
        
             
        
        
        
Answer:
a - 2
Step-by-step explanation:
Perimeter = side 1 + side 2 + side 3
So
6a + 3 = 2(a + 3) + (3a - 1) + side 3
side 3 = (6a + 3) - (2a + 6) - (3a - 1)
side 3 = 6a - 2a - 3a + 3 - 6 + 1 = a - 2
 
        
                    
             
        
        
        
6 hours to 1 book is a unit rate because the independent variable (books) is equal to 1.

You have said that Brigitte is shorter than 5 feet. Translating your statement into rigorous mathematical terminology, we would write "Brigitte's height is less than 5 feet.". Then, using 'h' to represent Brigitte's height, and '<' to represent the words "less than", we can write the statement symbolically as [ h < 5 feet ].
