Iset it to 25 use the distributive property to write an equivalent expression 1. 5y + 10 2. 10n + 15g the expression 10n + 13n + 75 represents the total cost in dollars for skis, boots, and a lesson for n skiers. simplify the expression. then find the total cost for 7 skiers.

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
