Answer:
t = 17.5 f = 12
Step-by-step explanation:
If <em>MNOP </em>is a square, you know that each angle is going to be 90°. To solve, let's first set each equation equal to 90°:

and

Then solve both equations:

and

I hope that helps!
 
        
             
        
        
        
The equation given in the question is
13 + (w/7) = - 18
(91 + w) / 7 = - 18
91 + w = - 126
w = - 126 - 91
    = - 217
I hope that the procedure is clear enough for you to understand. I also hope that this is the answer that you were looking for and the answer has actually come to your desired help.
        
                    
             
        
        
        
1 month = 17 536
6 months = 17 536 x 6
6 months = 105 216
