Pls help!! Pls and thanks!

Astudent received the following grades last semester. find the student's semester grade point average. an a is algebra (3 credits), a b in history ( 3 credits), a in sociology ( 3 credits) a d in english ( 3credits) and a c in seminar ( 2credits). an a is worth 4 points, a b is worth 3 points a c is worth 2 points and a d is worth 1 point.

Give me the equations of two lines that have the same slope but are not parallel.

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?
