Determine the length of LS
Since H is between L and S, then

Substitute 14x - 21 for LS, 15 for LH and 8x for HS

Collect Like Terms


Divide both sides by 6

Substitute 6 for x in 



<em>Hence, the length of LS is 63 units</em>
Just divide.

0.583333. . .
^ This is the thousandths place
Look at the number after that, if it's 5 or more we round up, if it's 4 or less we round down.
It's 3, so we round down to 0.583.
To find z, you have to divide -3 and 10, which you would get an odd number. That will be your answer for z :)
