Can somebody me with this question? solve for x?
2x−4/5=x+4

2x-4/5= x+4

Move 2x to the other side. Positive 2x changes into -2x

2x-2x-4/5= x-2x+4

-4/5= -x+4

Move +4 to the other side. Positive 4 changes into -4

-4/5-4= -x+4-4

-4/5-4= -x

Find the common denominator which is 5

-4(1)/5

-4/5- 20/5= -x

-24/5= -x

Multiply by -1 to get positive x and for -24/5

-24(-1)/5(-1)= -1(-x)

24/5= x

x= 24/5 or x= 4 4/5

Answer is x= 24/5 or x= 4 4/5

X = 4 4/5 (Four and four-fiths)

Step-by-step explanation:

Chances are your not reading this BUT if you are, if anything doesn't make sense, feel free to contact me for more help! :)

First I turned the minus 4/5 into a plus-negative:

2x + -4/5 = x + 4

Then I got rid of one of the X's by subtracting x (or 1x) from 2x, leaving you with 1x (or just x)

1x + -4/5 = 4

Then I subtracted the negative 4/5 (witch you can't really subtract a negative so its just like adding a positive 4/5). Which leaves us with:

1x = 4 4/5

Then you would divide both sides by one (or just do nothing it it's just a x)

So now you have your answer!

x = 4 4/5

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.
