maddy was one of the riders in the competition. If one judge awarded maddy a score of 87 and maddy's final score was 84.5 what score did the other judge award maddy answer

Respuesta :

Assuming there are two judges... and 84.5 is the average..
(87+x)/2 = 84.5

x=82

Let [tex] x [/tex] be the score awarded by the other judge.

Maddy's final score is the average of the scores awarded by the 2 judges.

So,

[tex] \frac{87+x}{2} =84.5\\
87+x=169\\
x=82 [/tex]

The score awarded by the second judge is [tex] 82\;points [/tex].
