How many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.

Write an inequality and solve each problem. for exercises 11 and 12, interpret the solution.

In the following diagram it is given that dec, ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2
