Question

what is x? 2/3x+6=27

Answer 1

You can do this on your own. Just remember what I did on the previous equation. try it yourself, you will learn better :)

Answer 2

okay so you subtract 6 from both sides right

Answer 3

correct, then?

Answer 4

it will be 3*2/3x=21.3 i think

Answer 5

how did you get 21.3?

Answer 6

i mean 21

Answer 7

no wait you multiply 3 in both sides

Answer 8

help me someone

Answer 9

right, you multiply by 3 on both sides, so what happens then?

Answer 10

then you multipy and x=63 right

Answer 11

for future reference when you mean 21 times 3 , write down 21*3, and not 21.3 :)

Answer 12

okay thank you

Answer 13

can u help me with -2(3x-6)=24

Answer 14

no, x is not 63, 2x = 63.

Answer 15

Answer 17

There are 200 lockers in your school, numbered 1 through 200 consecutively. The lockers are all closed to begin. Student #1 walks down the corridor and opens all the lockers that are numbered with a multiple of 1, thereby all the lockers are opened. Student #2 then walks down the corridor and changes the status (closed lockers are opened; open lockers are closed) of all the lockers that are numbered with a multiple of 2 (note that in the case of Student #2, this only involved closing lockers). Student #3 then walks down the corridor and changed the status of all the lockers that are numbered with a multiple of 3. By the end of this scenario, 200 students will have walked down the corridor, in numerical order, with each student changing the status of those lockers that are numbered with a number that is a multiple of the student’s number.

At that point, which of the lockers are open? More importantly, why are these lockers open?
