Mr. ray is trying to determine the median value of the class averages for his math classes. first, he must list the class averages in order from least to greatest. which list is in the correct order for mr. ray to use to find the median? a) 74, 77, 83, 86, 88 b) 74, 77, 86, 88, 83 c) 83, 86, 88, 77, 74 d) 88, 86, 83, 77, 74

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
