Answer:
x = 16
Step-by-step explanation:
Let the unknown number be x.
Translating the word problem into an algebraic expression, we have;
4x + 9 = 73
4x = 73 - 9
4x = 64
x = 64/4
x = 16
Therefore, the unknown number is 16.
 
        
             
        
        
        
Answer:
Its A
Step-by-step explanation:
Yes you are correct
 
        
                    
             
        
        
        
First, we must follow PEMDAS. (Parenthesis, exponents, division, multiplication, addition, and subtraction.).
We do what's in the parenthesis first.
9+9(2+4)÷3-2.
2+4=6.
Now our problem looks like this;
9+9(6)÷3-2 
OR
9+9×6÷3-2.
Anything in a parenthesis with no sign next to it, like this; 8(2), just means multiplication, so it would look like this: 8×2.
Next, we do all the multiplication in our problem.
9+9×6÷3-2.
9×6=54.
Now our problem looks like this;
9+54÷3-2.
Next, we do the division. 
9+54÷3-2
54÷3=18.
Now our problem looks like this;
9+18-2.
Next, we do the addition.
9+18-2
9+18=27
Now it looks like this;
27-2.
Finally, we subtract.
27-2=25.
Your final answer is 25!
Have a nice day! :)
