Which<br> expression is equivalent to 9q^2 - 2/3 (3q - 7) + 5q^2?
nikitadnepr [17]

Answer:

14q^2−2q+14/3

Step-by-step explanation:

9q^2 - 2q + 14/3 + 5q^2

Combine 9q^2 and 5q^2 to get 14q^2

14q^2−2q+14/3

Elena-2011 [213]
The median is the middle score, it is also the average of the two middle scores when total number is even.

with final score:  89,90,X,95  ----> median = 91.5

(90+x)/2 = 91.5
90+x = 183
x = 93

Final score was a 93.
