$500 * x^{-2}$ Answer:

all i can think of would be 10 to the power of a negative number

Step-by-step explanation:

example: say n = 5 and the exponent is -2

$5 * 10x^{-2}$

.05 = 1/20

as long as there is an equal amount or more negative numbers than digits of the original number.

like $5 * 10x^{-2}$ would be 5

this is all i can come up with the given info.

-1/3x+2x=3 3/4 what does the variable represent?

svet-max [94.6K]

Start off by combining like terms on the LHS (the terms with x in them).

So we get $\frac{-1}{3}x+2x= \frac{-1}{3}x+ \frac{6}{3}x= \frac{-5}{3}x$

Replacing this result with what we had before on the LHS, we get $\frac{-5}{3}x=3 \frac{3}{4}= \frac{9}{4}$

⇒Solve for x (divide both sides $\frac{-5}{3}$ )
⇒Don't forget about reciprocity rules when dividing. This is the same as multiplying both sides by $\frac{3}{-5}$

⇒ $x= \frac{9}{4}( \frac{3}{-5})
$
⇒ $x= -\frac{27}{20}=-1\frac{7}{20}$ ***This is a proper fraction
