5m + 72 = -2m + 52
5m + 72 + 2m = -2m + 52 + 2m
7m + 72 = 52
7m + 72 - 72 = 52 - 72
7m = -20
7m/7 = -20/7
m = -20/7
Just divide by 2 2/8 2/4 6/8

Answer:
<em>The sea cow can stay under water for 16 minutes.</em>
Step-by-step explanation:
A hippopotamus can stay under water for 15 minutes.
A sea cow can stay under water
minutes and this is 11 minutes longer than one-third the time a hippopotamus can.
So, "11 minutes longer than one-third the time a hippopotamus can" means: ![[\frac{1}{3}(15)+11] minutes](https://tex.z-dn.net/?f=%5B%5Cfrac%7B1%7D%7B3%7D%2815%29%2B11%5D%20minutes)
Thus, the equation will be: 
Now, solving the above equation, we will get.........

So, the sea cow can stay under water for 16 minutes.
