The buses in the school parking lot can carry a total of 626 students. Some of the buses can carry up to 66 students and the remainder of the buses can carry up to 74 students. This situation can be represented by the equation 66x + 74y = 626. In this equation, what does x represent?

Which of the following would be a correct step in proving that triangle abc is congruent to triangle cda? a. use a protractor to measure the angles and show that all the corresponding angles are equal in measure. this will allow you to prove congruence by aaa. b. show that segment ab is parallel to segment cd and segment ad is parallel to segment cb. this will allow you to prove congruency by asa. c. show that is segment ab is perpendicular to segment ad. this will allow you to prove congruence by sas. d. none of the above.
