22. √125 is closer to √121 or 11

23. √23.5 is closer to √25 or 5

24. ∛59 is closer to ∛64 or 4 (cubed)

(4 cubed = 64, 3 cubed = 27)

solve the equation 5 over 4 minus 1 over x minus 2 equals -4 over 4x minus. use complete sentences to explain how you solved the
ehidna [41]
Let's translate your words into numbers and fractions. So it's
5/4 - 1/x - 2 = -4/-4.
Let's Simplify it first by eliminating -4/-4, the answer will be 1 since negative divided by negative is positive and 4 divided by 4 is 1.

5/4 - 1/x - 2 = 1

Then Get the GCF of the equation which is 4x.
Then divide the whole equation by 4x and it would be, 

<span><u>5/4 - 1/x - 2 = 1
</u></span>        4x

Then it will look like this, 5x-8x-4 = 4x
Then transpose, 5x - 8x - 4x = 4
Simplify by deducting the left side. -7x = 4
Then divide both sides by -7.
Then the final answer would be x = -4/7
