10x - 22 = 29 - 7x. what is the value of x

x=3

Step-by-step explanation:

You have to do the opposite of the operation to get the like terms on the same side of the equation sign. You have to add 22 to 29 (you add because its originally subtracted, or negative) and you add 7x to 10x. Then divide 51 by 17x giving you 3.

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.
