A hippopotamus can hold its breath for about 15 minutes. It can hold its breath 5 minutes longer than a sea otter. Use an equation to find how long a sea otter can hold its breath. A. 5 minutes B. 10 minutes C. 15 minutes D. 20 minutes

B. 10 minutes

Step-by-step explanation:

Let x represent the number of minutes that a sea otter can hold its breath. A hippopotamus can hold its breath for 5 minutes longer than x. So, the equation would be:

x + 5 = 15

Subtract 5 from both sides.

x + 5 = 15

x + 5 - 5 = 15 - 5

x = 10

A sea otter can hold its breath for 10 minutes.

Hope that helps.

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
