Step-by-step explanation:
Make a proportion:
66/12 = (104-r)/r
Simplify:
r = 16
5/12lb of dog food in each container.
This seems like a division problem so you would take (5/4) and divide it by 3 to make 3 equal groups meaning 5/12lb would be in each container.
I hope this helps, good luck!
We have to find midpoint M of the diagonal AC (or BD, there is no difference) so:
Yes, you got it! You would need to set the equations equal to each other, because that represents when their populations are the same. Then, solving for x will find the time in months until you reach that equilibrium in population. If you need help solving for x, just comment on this. Hope it helps!
The shirts are 12.75 for 3 so we can write a ratio of

To get the price of the shirts, one needs to divide

, which will tells use what the unit price is per shirt. The price per shirt is $4.25
