10x3=30 hours
30/4= 7.5 hours to study for each exam
I believe you can do x + 2.7 = 16.
I took geometry last year and those arrow things are basically saying the line is the same if they have the same number of arrows. Using that logic, you can equal them out and find X.
Your answer is 16 - 2.7
(13.3)
0/11, The slope of the line would be undefined.
I had that problem before on a test i got it wrong :(
