Complete the solution of the equation. find the value of y when x equals 11 -2x+9y=5

-2x + 9y = 5, where x = 11

Plug in 11 for x in the equation:

-2(11) + 9y = 5

Solve for y:

-22 + 9y = 5

9y = 27

y = 3

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

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.
