A student scored a 76, 84 and 90 on his first three quizzes. Solve a compound inequality to find the possible values for the fourth quiz, x, that would give him an average between 80 and 85 (not inclusive).

Answer :

Answer:

83.333...

Step-by-step explanation:

In order to find the answer, you need to add 76+84+90.

You would get 250.

You would need to divide it by 3 because the student has only done 3 tests so far so you would get 83.333....

So, the possible value that the student might get in his fourth quiz is 83.333...

Hope this helps:)
