At the county fair, the operator of a game guesses a contestant's weight. For each pound the operator's guess differs from the contestant's weight, the contestant will receive $3. If a
contestant received $15 when the operator guessed 120 pounds, what are the possible values
for the weight of the contestant?

Which of the following is an example of an opposing signal? no examplthates given.   i would say, that traffic lights in a city at major intersections direct the flow of traffic in opposite directions so would be an example.also, stop signs on either side of the same street would be an example. at a train crossing, the light for allowing car traffic in opposite directions or not would be another example.
