Given: `deltaabc` with `bar(de)` || `bar(ac)` prove: `(ad)/(db) = (ce)/(eb)`statementreason1. `bar(de)` || `bar(ac)`given2. `/_ cab~=/_edb` `/_acb~=/_deb`if two parallel lines are cut by a transversal, the corresponding angles are congruent.3. `deltaabc ~ deltadbe`aa criterion for similarity4. corresponding sides of similar triangles are proportional.5. ab = ad + db cb = ce + ebsegment addition6. `(ad + db) /(db) = (ce + eb) /(eb)`substitution property of equality7. `(ad)/(db) + 1 = (ce)/(eb) + 1`division8. `(ad)/(db) = (ce)/(eb)`subtraction property of equalitywhat is the missing statement in the proof? scroll down to see the entire proof.

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
