Chen was asked to solve the inequality: 2x-5(x-1)< 50. she gave an answer of x < -15 substitute in any value for x less than -15 to determine if chen is correct. if not, determine the correct solution

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
