A car backs up 29 feet, followed by 8 more feet. The car's position can be represented by the sum -29+(-8). Find the sum. Use pencil and paper. Represent the situation with a drawing. Superimpose a number line in the drawing to represent the situation in a third way.

Danny draws a transversal, t, on two parallel lines ab and cd, as shown below: he makes the following table to prove that the alternate interior angles are equal: which is the missing justification? (6 points) corresponding angles formed by a transversal on parallel lines are supplementary. corresponding angles formed by a transversal on parallel lines are congruent. co-interior angles formed by a transversal on parallel lines are congruent. co-exterior angles formed by a transversal on parallel lines are congruent.
