i will give brainliest

130ft

Step-by-step explanation:

233-63=170. 170-40=130ft.

Your answer is -110 feet, or 110 feet below sea level.

Step-by-step explanation:

depth of 233 feet below sea level = -233 [feet]

rises 73 feet                                     = +73

comes up another 40 feet              = +40

Equation:

- 233 + 73 + 40 = ?

||

   -150      +  40 = ?

      ||

            -110       =  ?

So the grey whale is feeding at -110 feet, 110 feet below sea level.

I hope this helps!

(3x-8) or (3x+8)

step-by-step explanation:

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
