Mathematics help please!!!!!!!!!<br><br> what is -0.0833333333333 converted into a fraction?
VladimirAG [237]

Answer:

- 1/12

Step-by-step explanation:

Let -0.0833333 = x  ---  (1)

Multiply both sides by 10.

-0.833333 = 10x   --- (2)

Subtract (2) from (1),

0.75 = -9x

-9x = \frac{75}{100}

= \frac{3}{4}

x=-\frac{3}{36}

x=-\frac{1}{12}

Answer:

➩ x=2,-\frac{2}{3}

Step-by-step explanation:

\sqrt{4x^2}=x+2

➨ We can also solve by completing both squares, however. Since we can pull out the square root.

\sqrt{4x^2}=|2x| ➩ Define of Absolute Value/Square Root

➩ \sqrt{x^2}=|x|

Thus, our new equation is ➩ |2x|=x+2

To solve an absolute-value equation, let there be two conditions.

➨ Where x ≥ 0

2x=x+2\\

Move x to another side

2x-x=2\\x=2

➨ Where x < 0

-2x=x+2\\-2x-x=2\\-3x=2\\x=\frac{2}{-3}\\x=-\frac{2}{3}
