At the Nike factory, they ship their merchandise to stores in boxes that have a volume of 240 cubic feet. Each shipment usually has 25 adult sneaker boxes
that each have a volume of 5.2 cubic feet. They fill the rest of the box with kid
sneakers that each have a volume of 27 cubic feet. How many boxes of kid
sneakers can they fit in each shipment?

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.
