We can represent her initial position as -24.25, since it says she is 24.25 feet below sea level.
If she descends -.5 feet per minute, all we have to do is multiply -.5 by 25, and add it to her initial position to get the answer.
-.5*25=-12.5
-24.25+-12.5=-36.5
Her current position is -36.5
Hope this helps!

I hope this answer will help you. Have a nice day !
the correct answer should be (b) 6 is extraneous.
If you look at the second row of the solution you see (x-6) as a factor in one of the denominators. That's a problem: if 6 were a solution this denominator would become 0. But denominators being 0 is bad (undefined), so while 6 comes out of the algebraic manipulation as a solution, it is invalid, or extraneous.
-3 is a fine solution.
