Well us as kids are constantly on the computer and phones so google classroom is a great way to keep us connected with our teachers because we can communicate with them and they with us by posting assignments. Therefore we are less likely to forget what they told us in the classroom because it is just one click away.
        
             
        
        
        
Answer:
The difference is 30%
Step-by-step explanation:
To find the percent decrease, start by finding the difference in costs. 
42.54 - 29.78 = 12.76
Now divide that amount by the original cost. 
12.76/42.54 = 30%
 
        
             
        
        
        
Well, I don't really understand if it is 30 or 305 because of the spacing but I'll answer both. If it is 5y+305, just divide the whole equation by 5 and it will look like this (<u>5y+305)</u>  then the factor would be 5(y+61)<u>
</u>                   5 
If it is 5y+30 it would be just in the same process, Divide the equation by 5 and the result will be 5(y+6).
        
             
        
        
        
Fractions that aren't equivalent would be 30/60, 34/60 and anything that cannot be the same as 36/60.
