Respuesta :
I would say 22 i first looked at amount of average kids in a class then tried every number close. 484/22=22
Let the total number of kids in Mr. Levans' 3rd grade class be x.
We know that each kid in the class made a Valentine for every kid in the class, including himself or herself.
So, the first kid made x Valentines. Likewise, the second kid too made x Valentines. If we go on so on and so forth, we will note that even the last, or the [tex] x^{th} [/tex] kid made x Valentines too. Thus, this way we know that every kid made x Valentines.
Therefore, the total number of Valentines made are [tex] x\times x [/tex]. It is given in the question that the number of Valentines made is 484.
Therefore, from the above information we conclude that:
[tex] x\times x=x^2=484 [/tex]
To find x we will have to take the square root of both sides. Which will give us:
[tex] \sqrt{x^2}=\sqrt{484} [/tex]
[tex] x=22 [/tex]
Thus, the number of kids in the class is 22.
