Anybody know the multiple choice answer? Add all the distances Zeno would travel each time. How far would Zeno go?

2y= 3 2 x−2 y = − 1 3 x + 1 y=− 3 1 x+1

It says factor each expression completely 8y+48

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.
