Answer:

9/7

Step-by-step explanation:

with any negative power, we have to find the reciprocal of the base. in this case, it is 9/7. then, apply the exponent to the fraction. now, it is 9^1 over 7^1. we can just write it as 9/7 because if the exponent is 1, it is just the value of the base, so it is not written.

Nonamiya [84]

The number of points Marco needs to bring his average up to 90% is 15points.

If there's a possible 25 possible points, and Marco has taken 5 quizzes;

Evidently, each quiz has weighs 5 points.

Mathematically;

\frac{21 + 5x}{5(5 + x)}  \times 100\% =  \frac{90}{100}

  • 2100 + 500x = 2250 + 450x

  • 50x = 150

x = 3.

Therefore, he needs 5x points = 15 points to bring his average up to 90%.
