Ihave had 2 friends me with this and they got different answers one was 1 and 1/30 the other one was 8 and 1/6 over 7 so can someone question:
3 1/2 over 5 + 4 2/3 over 2.

Given: lines a and b are parallel and line c is a transversal. prove: 2 is supplementary to 8 what is the missing reason in the proof? statement reason 1. a || b, is a transv 1. given 2. ∠6 ≅ ∠2 2. ? 3. m∠6 = m∠2 3. def. of congruent 4. ∠6 is supp. to ∠8 4. def. of linear pair 5. ∠2 is supp. to ∠8 5. congruent supplements theorem corresponding angles theorem alternate interior angles theorem vertical angles theorem alternate exterior angles theorem

With number 11 ( show how you got the answer)

Yvaries inversely as x. y =12 when x=5. find y when x=4
