To find average you add then divide by how many.
So, we can reverse because ? divided by 25 = 3 75 would be the mystery number because of the equation above. If you add 8 to 75 then divide by 26 ( new student ) you get 3.19230769

Answer:

12

Step-by-step explanation:

8·15·h=1440

120·h=1440

\frac{120h}{120}=\frac{1440}{120} (Divide both sides by 120)

h=12

<em><u>h stands for height</u></em>
