Can someone me? someone explain to me how to do problems like x - 2/5 = 7
and x + 4/5 = 11? i don't really need the answers, i just can't understand : ///like how do i solve what x equals?

Step-by-step explanation:

the first question

x-2/5=7

you need to use the same rules as pemdas but sorta in reverse. starting with multiplying 7 by 5, which is 35

x-2= 35

then you would add 2 to 35

making the answer x=37

You'd follow the same steps for the second one.

let me know if you have any questions

I hope this helped

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.
