The data shown are the final exam scores of 10 randomly selected math students and the number of hours they studied for the exam. the equation of the line of best fit for this data is a) y = 56.11x - 5.044 b) y = 5.044x + 56.11 c) y = -56.11x - 5.044 d) y = 5.044x + 5.044

The sum of the reciprocal of a positive number and the reciprocal of 2 more than the number is 3/4 equation: the number is

If i have 20$ and i gave 5$ away how much i got

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.
