I’ll give the Brainliest to who answers the question with and reasonable explanation. When is the constant of proportionality the same as the unit rate when comparing two quantities?

A. Only when the two quantities are indirectly proportional

B. Only when the two quantities are directly proportional

C. Always

D. Never

Thank you!

In the diagram, the ratio of ab to ae is (1/2) . what is the ratio of the length of to the length of ?

Asays "we are both knaves" and b says nothing. exercises 24–31 relate to inhabitants of an island on which there are three kinds of people: knights who always tell the truth, knaves who always lie, and spies (called normals by smullyan [sm78]) who can either lie or tell the truth. you encounter three people, a, b, and c. you know one of these people is a knight, one is a knave, and one is a spy. each of the three people knows the type of person each of other two is. for each of these situations, if possible, determine whether there is a unique solution and determine who the knave, knight, and spy are. when there is no unique solution, list all possible solutions or state that there are no solutions. 24. a says "c is the knave," b says, "a is the knight," and c says "i am the spy."

Which equation results from adding the equations in this system? x+6y=9 and -x+2y=-15
