Is x = 1 the solution to 2(x + 13) = 28
(show me why! Or maybe why not)

Yes, x=1 is the solution

Step-by-step explanation:

You would divide both sides of the equation by 2, that leaves you with x+13=14

Next you would move your constant, which in this case is 13, so x=14-13

Then you would subtract the numbers by each other so 14-13 equals one which makes x=1

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.

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
