A sperm whale can stay under water 7 times as long as x minutes more than a platypus can. Write and equation that states the relationship of the minutes these two mammals can stay under water.
Sperm Whale- 112
Platypus-10
My answer: 7x+10 x=112
Is my answer correct?
7(x+10) = 112
I parsed the words as
7 times as long as (x minutes more than a platypus)
Sorry for the last comment,just trolling (Didn't think they will allow me to post :o). But 112 is the min. he can stay under water, so 10*7x=112?
How is it 7(x+10) = 112 @Steve
Sorry,I don't get it :(
