Dwayne is selling hamburgers and cheeseburgers. He has 100 burger buns. Each hamburger sells for $3, and each cheeseburger sells for $3. 50. Which system of inequalities represents the number of hamburgers, h, and the number of cheeseburgers, c, he must sell to have sales of at least $80? h + c ≤ 80 3h + 3. 5c ≤ 100 h + c ≤ 80 3h + 3. 5c ≥ 100 h + c ≤ 100 3h + 3. 5c ≤ 80 h + c ≤ 100 3h + 3. 5c ≥ 80.

It is good, unless you eat a lot of it. it contains sugar.

Maybe c. im not too positive

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.
