Beverly has a bag of marbles that weighs 30 grams. She knows that each marble weighs 1. 5 grams and the bag weighs 1. 5 grams. Which equation could she use to determine how many marbles are in the bag? select all that apply. (1. 5)x + 1. 5 = 30 30 – x = 2(1. 5) (1. 5)(30) = 1. 5x 1. 5 + x = 30 1. 5x = 30 – 1. 5.

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.

One of the angles would be 70 degrees and the other one would be 90 degrees
