Solve by setting up a system of linear equations with 2 variables and 2 unknowns. two hundred seventy six students enrolled in a freshmen-level chemistry class. by semester’s end, 5 times the number of students passed as failed. find the number of students who passed the chemistry course.

What is the simplified expression for 6(2(y+x))

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
