Answer 1

Answer:

$x=89$

Step-by-step 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!
