What does average at least a 65% on the midterm and final combined mean?

Question

I got a 52% on the midterm can I still pass the class 

Answer 1

It means your average grade on the midterm and final needs to be 65%.

In equation form, x + 52 = 65

                                  2

x + 52 = 130

         x = 78% - the grade you need on the final exam
