Well.. an hour is.. 60 seconds.. but, 1/2 an hour is.. 30 seconds.. And if the elves ate 327 cookies, you would have to divide 327/100 * 30, and that would be.. 1,090 rates in cookies that they ate per hour! Hope I was able to help! And.. if you can, please give me Brainliest! I would really appreciate it! Merry Christmas, and God Bless you, and your whole family! Be/stay safe, and have a good rest of your day! :)
        
             
        
        
        
Step-by-step explanation:
13x+7y-2x+6a
combine like terms
=13x-2x+7y+6a
=11x+7y+6a
simplified
 
        
                    
             
        
        
        
An equation that represents this is 
(5-20-18)+25
The steps to solve it are as follows
(-15-18)+25
-33+25= (-8)
