The table shows the elevation in feet at the peaks of several mountains.

polet [3.4K]

Answer:

a) The equation to find the elevation of Mt. Wilson is $28,784.31=x+11,510.21$

b) The elevation of Mt. Wilson is $17,274.10\ ft$

Step-by-step explanation:

Let

x ----> represent the elevation of Mt. Wilson

y ----> represent the elevation of Snow Crest

we know that

$y=x+11,510.21$ ----> equation A

we have

$y=28,784.31\ ft$

Substitute the value of y in equation A and solve for x

$28,784.31=x+11,510.21$

$x=28,784.31-11,510.21$

$x=17,274.10\ ft$
