HELP!!
You can eliminate fractions from the equation 3/4 x−1/2=5/6 by multiplying by what

12

Step-by-step explanation:

hello! You just need to find the GCD of 4, 2, and 6 to elimate all the fractions, GCD(4, 2, 6) = 12, so if you multiply by 12, you get: 9x-6=10.

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

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.
