Answer:

A score between 84 and 99

Step-by-step explanation:

First, let's solve for what you would need to score on your next test to have an average of 84:

(81 + 87 + x)/3 = 84

     (168 + x)/3 = 84

          168 + x = 252

                    x = 84

Next, let's solve for what you would need to score on your next test to have an average of 89:

(81 + 87 + x)/3 = 89

     (168 + x)/3 = 89

          168 + x = 267

                    x = 99

That means you would have to earn a score between 84 and 99.

I hope this helped you, and if it did, a brainliest would be appreciated :)

Step-by-step explanation:

Writing out the expression Mathematically ;

Using PEMDAS :

Solving the bracket first

(-15 ÷ 1/2) = (-15 * 2/1) = - 30

We have :

1/3(-30)1/4 = - 10 * 1/4 = - 10 / 4 = - 2.5
