Paul has two label-printing machines. Each machine can print 30 labels per minute. On day 1, only the first machine was used, and it printed 90 labels. On the following day, the first machine printed for x minutes and the second machine printed for y minutes. Which expression shows the total number of labels printed by both machines during these two days?

Two sides of a triangle mesure 20cm and 30cm. what is the measure of the third side

100 points, hi, i’m not sure how to get the equation from the graph and table.

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.
