The given equation has been solved in the table. Step 1: x/2 - 7 = -7
Step 2: x/2 - 7 + 7 = -7 + 7
Step 3: x/2 = 0
Step 4: 2 . x/2 = 2 . 0
Step 5: x = 0

In which step was the subtraction property of equality applied?

A. Step 2
B. Step 3
C. Step 4
D. The subtraction property of equality was not applied to solve this equation.

answer: x= -2y

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.
