On a road trip with a friend, you drove 70 miles per hour and your friend drives 60 miles per hour. The two of you want to drive less than 15 hours at
least 600 miles per day. Your friend will drive more than you. Write a system
of linear inequalities to find out how many hours can you and your friend drive
per day.

The graph shows the distance kerri drives on a trip. what is kerri's speed . a. 25 b.75 c.60 d.50

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.

How can constraints be used to model a real-world situation?
