Fatima is walking home from her city high school. Her average speed is 2 blocks per minute, and her school is 15 blocks from her home. Let m represent the number of minutes since Fatima left her school, and let b represent the number of blocks between her and her home.
Which two of the following equations correctly model Fatima's walk home from school?
Ob= 2m - 15
Ob= 15 - 2m
2m = b - 15
2m - b = 15
2m + b = 15

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.
