2/3x-4 =20 what do i do with the 2 over 3?

I believe you mulitply by 2/3 on both sides to undo the divison

Hope this helps :)

Any time you have a number right beside a variable you always times them but for that reason you don’t knwo what x is so you would cancel out the -4 to the 20 then you would get that answer then that answer you get is the answer for x

Step-by-step explanation:

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
