Question

Adam is scuba diving. He descends 5 feet below sea level. He descends the same distance 4 more times. What is Adam's final elevation?

Answer 1

I think it's 20 because 5 feet times 4 more times equals 20.

5*4=20

So 20 feet?

I think that's right, and I hope it helps :)

Answer 2

It would be -25

Explanation:

Because your going below sea level 5 times you would go to the left 5 times

( - 5 )

l--l--l--l--l--l--l--l--l--l--l--l--l--l--l_l

5 0

Then he goes 4 more times down at the same distance (-5 times)

-5 -5 -5 -5 -5 l

--l-----l----l----l------l-----l l

25 -20 -15 -10 -5 0 l

1 2 3 4) 1 l

(other 4 times) (1st time) l

l

So its 5 x 5 cause your adding the first time you moved 5 to the left with the other 4 times you moved to the left 5 times And so 5 x 5 = -25

The equation is 5(-5) = -25
