Ageologist found two underground wells that contained large deposits of water. the first well was 46 2/3 meters below the surface. the second well had more water, and was 77 5/6 meters deeper than the first well. how deep below the surface was the second well?

Second well was   deep below the surface.

Step-by-step explanation:

Given:

Depth of First well =

can be Rewritten as

Depth of First well =

Also Given:

The second well had more water, and was  deeper than the first well.

can be Rewritten as

Hence We can say that;

Depth of second well is equal to   plus Depth of First well.

framing in equation form we get;

Depth of second well =

Now the denominators are common so we can solve the numerators

now to solve the fractions we need to make the denominator common we will use L.C.M we get;

Depth of second well =

Now the denominators are common so we can solve the numerators.

Depth of second well =

Hence Second well was deep below the surface.

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
