Question

Please help me. I don’t understand this problem.

Answer 1

Answer:

d = 637 ft below the surface

Step-by-step explanation:

Given

P = 14 + $\frac{6}{13}$ d

To find d when P = 308, then

14 + $\frac{6}{13}$ d = 308 ( subtract 14 from both sides )

$\frac{6}{13}$ d = 294 ( multiply by 13 to clear the fraction )

6d = 3822 ( divide both sides by 6 )

d = 637 ft

Answer 2

Answer:

       637 feet

Step-by-step explanation:

$P=14+\dfrac6{13}d\\\\\\P=308\,,\qquad\qquad d=??\\\\\\308=14+\dfrac6{13}d\\\\ 308-14=\dfrac6{13}d\\\\294=\dfrac6{13}d\\\\d=294:\frac6{13}\\\\ d=294\cdot\frac{13}6\\\\d=637\,ft$
