The first equation in the system of equations that models this situation is x + y = 70, where x represents the number of 2-point
questions and y represents the number of 4-point questions. What is the other equation in the system? Enter the correct answer in the box. Substitute numerical values in the expression for A, B, and C.
I believe it would be B. Logically, it’s the only one that makes sense, As 9x10= 90 None of the others have any way to divide or multiply up to the area, So yes, B.
