It is given that ∠abr and ∠acr are right angles, ab ≅ bc and bc ≅ ac since they contain right angles, △abr and △acr are right triangles. the right triangles share hypotenuse ar, and reflexive property justifies that ar ≅ ar. since ab ≅ bc and bc ≅ ac, the transitive property justifies ab ≅ ac. now, the hypotenuse and leg of right △abr is congruent to the hypotenuse and the leg of right △acr, so △abr ≅ △acr by the hl congruence postulate. therefore, by cpctc, and bisects ∠bac by the definition of bisector.

You call the pizza store and find out that eachpizza has 12 slices. you expect 16 people tocome, and you estimate each person will eat 3slices. how many pizzas should you order

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
