Question:

If 7+3x=22, then 2x=?

Inactive
David L.

IF 7+3x=22, you can subtract 22-7=15. That means 3x=15. 15/3=5, so x=5. If we know x=5, then 2x=10

Question:

In a bag of 400 jelly beans, 25% of the jelly beans are red in color. If you randomly pick a jelly bean from the bag, what is the probability that the jelly bean picked is NOT one of the red jelly beans?

If 25% of the jelly beans are red, then .25*400=100 red jelly beans. If 100 jelly beans are red, then 300 must be a different color. That means that 300/400=.75, so there is 75%, or 3/4th's chance the jelly bean picked will not be red.

Question:

The premature loss of a flight feather to injury, then, is not an incidental matter to raptors, most of which are diurnal.

The above sentence should end at the word "raptors." The next sentence should then cover the fact that most raptors are diurnal.
