The volume of a fish tank is 70 cubic feet. if the density is 0.4 fish over feet cubed, how many fish are in the tank?

There would be 16 fish in the tank

could you reply to this with the question so i can ?

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
