Base on your question were the are proofs that is given are this are: CB bisects BD, DE bisects EC, CB=DE. So answer your question you must understand first your given statements and realize that CBD and DEC are both right triangles because they are a perpendicular segment so i conclude that the answer should be CBD=DEC because they are both right angles
27 divided by 3 = 9
9 times 5 = 45
No the inequality symbol only changed when you divide a negative number from both sides.
