Answer:
The expression will be x = 30/6 and she'll have 5 buttons in each box.
Step-by-step explanation:
In order to write the expression for the number of buttons in each box we first need to attribute a variable to that value, in this case we will use "x". The number x will be given by the division of all the buttons she has by the number of boxes she wants to organize them in. We have:
x = (number of buttons)/(number of boxes)
x = 30/6 = 5 buttons per box
The expression will be x = 30/6 and she'll have 5 buttons in each box.
