HELPPPP!!!!! PLEASEEE IM BEING TIMED !!!!!!!!!!!

Answer 1

`x=89`

Explanation:

We can plug into the formula for the mean to get
`(87+73+84+82+x)/5=83`.

We can combine like terms on the left side to get
`(326+x)/5=83`.

We can multiply by
`5` on both sides to get
`326+x=415`.

We can finally subtract
`326` from both sides to get
`x=89`.

So, the answer is
`\boxed{x=89}` and we're done!
