B. Undoing Division Method: In this ratio, x is divided by 1505. You can undo the division by multiplying each side of the proportion
by 1505 like this:
(1605) = 1505 (1505)
Explain how this strategy works.
Are the two ratios still equal?
Why are both sides multiplied by 1505?
Simplify each side of the equation and find x.

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
