5. The fifth grade collected plastic water bottles to recycle. The number of pounds of water bottles they collected rounded to the nearest tenth is 125.5 pounds. What are 3 possible
numbers that could be the actual number of pounds of water bottles they collected?
Pick one of the numbers above and explain why you chose that answer using words,
numbers, or pictures.

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.
