what is a first step to solving for X in the equation 9X -7 equals=10? How would you check your solution

The first step is to isolate the constants on one side of the equal sign

Step-by-step explanation:

9x - 7 = 10

The first step is to isolate the constants on one side of the equal sign

9x - 7 = 10

    +7     +7

9x = 17

9    9

x = 1.8

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.
