Answer 1

Deepest Point ===> 11,542

Deepest Point of Lake Relative to it's Surface =====> -922

Absolute Value Explained:

d = 11,542 + | -922 |

Solve:

d = 11542 + | -922 |

Simplifies to:

d = 12,464

Answer: Depth ======> 12,464

Absolute Value: ====> d = 11,542 + | -922 |

Hope that helps!!!! : )
