Answer:
The number of 57-cent stamps that Julie bought is 12
Step-by-step explanation:
Given equation
0.57 s + 0.3 ( s − 6 ) = 8.64
Open bracket
0.57s + 0.3s - 1.8 = 8.64
Collect like terms
0.87s = 8.64 + 1.8
0.87s = 10.44
Divide both sides by 0.87
s = 12
The number of 57-cent stamps that Julie bought is 12
 
        
             
        
        
        
The answer is 9/5
You do 9x1/5 so 9x1 is 9. That’s your numerator and 5x1 is 5 and that’s your denominator

Answer:
   9n^4
Step-by-step explanation:
The divisor and quotient can be interchanged to find the divisor:
   
Such division is carried out by first finding the quotient of the highest-degree terms:
   
This value is used to multiply the denominator and subtract that product from the numerator to find the new numerator. The new numerator is zero, so the value that goes in Blank 1 is ...
