Let's look at the equation we have.
18x + 2x = 31

The first step would be to combine like terms. Ex: 18x and 2x
18x + 2x = 31
20x = 31

Now, to isolate the x, you would divide both sides by 20.
20x = 31
x = 1.55

x = 1.55

I hope this helps!

Answer from: maleah12x

Take 18x + 2x= 31
Combine like terms; 18x and 2x
20x=31
Now divide both sides by 20.
The 20 crosses out on the right and the x is now by itself.
And 31 divided by 20 is 1.55.
Therefore the answer is x=1.55

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.
