Put x + 2y=4 into slope-intercept form? y=mx+b format

If t17 = 3 (t5) in an arithmetic progression, find t1 in terms of d.

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

Idon't get undoing if its pass adding and subtracting so can someone ? x-2 over 5 = 18
