3.2x+2.6= -23 please. She is step by step so I can understand

x = -8

Step-by-step explanation:

To find x, we need to isolate it. So first, let's subtract 2.6 from both sides to get rid of it on the side with x:

Now, divide both sides by 3.2 (because notice how we are multiplying it right now - so we need to undo that, and so we do the inverse operation of division):

Notice how we are left with 1x on the left which is x, so we have successfully isolated x:

So, x = -8. Hope it makes sense, ask me any questions you may have! :)

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.
