<u><em>Answer:</em></u>d = 25
<u><em>Explanation:</em></u>To get the value of d, we will need to isolate the d on one side of the equation.
<u>This can be done as follows:</u>
</span>

<span>
<u>First, we will do cross multiplication as follows:</u>
40*15 = 24*d
600 = 24d
<u>Then, we will isolate the d as follows:</u>
24d = 600

d = 25
Hope this helps :)</span>
here is a contradiction because in one inequality x can be equal to 15 ; and in the other it cannot
we know that
the rate of elevation is 2 feet per minute
so
Find out the elevation in 10 minutes
Multiply 2 ft/min by 10 min
2*10=20 ft
therefore
her elevation 10 minutes ago is
0-20=-20 ft ----> is negative because is below sea level
the answer is
-20 ft or 20 ft below the sea level
