Hudson is making smoothies. Each smoothie uses 2/3 cup of yogurt. How many cups of yogurt does he need to make 16 smoothies? Express your answer in simplest form.

What's the difference between: x≥0 and nonnegative integer. ?

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.

Are the corresponding angles congruent? explain why or why not.
