Answer: 4 fishes
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a sphere = 4/3 x π x (diameter/2)^3
Replacing with the values given:
V = 4/3 x π x (18/2)^3
v = 4/3 x π x (9)^3 = 3,053.63 in3
Next, we have to divide the volume of the tank by 693 in3 (volume for each fish)
3,053.63/693 =4.40 = 4 fishes
Feel free to ask for more if needed or if you did not understand something.

-12x=7
x=-7/12
