Answer: 17
Step-by-step explanation:
78 x 9
=702
702 -719
= 17
 
        
                    
             
        
        
        
In triangle the sum of the angles =180,and we have angle=124 so,180-124=56.
X=4
        
             
        
        
        
If you would like to know what was the temperature after the increase, you can calculate this using the following step:
the beginning temperature: -9
increased: 37
the temperature after the increase: -9 + 37 = 28oF
The temperature after the increase was 28oF.
        
                    
             
        
        
        
First lets remove the initial fee

150 is how much she is charging you per hour.
If each hour is 55, lets divide 150 by 55.

She charged you for 2.7 hours (almost 3) of service
 
        
        
        
As the front approaches, you will have a storm.
I hope this helps!
