Heather earns $16 for each hour she works as a lifeguard. Choose the equation that models the situation, where h represents the number of hours she works and m represents the money she earns. m = 16 - h m = 16 h (0) m = 16h m = 16 + h ()

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
