Carly rides her bike 6.8 miles. Ben rides his bike 0.85 times as far as Carly rides hers. Part A
Which expression shows how far Ben rides his bike?
6.8 + 0.85
6.8 – 0.85
6.8 × 0.85
6.8 ÷ 0.85

How far does Ben ride his bike

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.
