a hippopotamus can remain under the water for twenty five minutes. it takes a hippopotamus three minutes to come to the surface for air before going under the water again. A hippopotamus stays in the water for four hours. how many times can the hippopotamus go under the water for twenty five minutes and come to the surface for air? show all your mathematical thinking
Answers
Answer 1
Answer:
9 times because 4 hours is 240 minutes and 240 / 25 is about 9.
that is the product of a fraction and two numbers: (1/10)(12)(16) = 12*16/10 = 19.2
1/10(12*16) = 1/10*192 = 19.2

What is 10t=6t+24 than you!
Answers
When you solve an equation, the most important thin got remember is isolate the variable. So try to get t by itself using order of operations backwards.
10t = 6t + 24 Subtract 6t from both sides to get the t's on one side.
4t = 24 Divide both sides by 4 to get t completely alone.
