Answer:

±2/11

Step-by-step explanation:

Take the square root of both sides of the equation:

$\sqrt{x^2}=\sqrt{\dfrac{4}{121}}\\\\\boxed{x=\pm\dfrac{2}{11}}$

_____

Here, we need to recognize that (-2/11)^2 = (2/11)^2 = 4/121, so both the positive and negative roots of 4/121 are solutions to the equation.

Add and simplify the result, if possible. x/18 + 3/18

Slav-nsk [51]

$\frac{x}{18}$ and $\frac{3}{18}$ both have a common denominator, so you can combine them into a single fraction:

$\frac{x}{18}+\frac{3}{18}=\frac{x+3}{18}$

You cannot simplify this fraction further:

- - - - - - - - - - - - - - - - - - - -

Answer:

$\boxed{\frac{x+3}{18}}$

- - - - - - - - - - - - - - - - - - - - -

128 to the nearest 100

Radda [10]

The answer is 100 because 128 is closest to 100. in order for it to be 200, it has to be over 150

In JKL. solve for x 66.73 74.89 15.44 38.16

liq [111]

By right triangle trigonometry, the sine of the measure of an angle is the ratio of the opposite side of this angle to the hypotenuse.

Thus, $\displaystyle{\sin27^{\circ}= \frac{34}{x}$

$\sin27^{\circ}$ is a constant which can be found using a calculator:

with calc in pc: view → scientific → 27→sin = 0.45399,

thus x=34/0.45399=74.89

Answer: 74.89

Answer:

3*r = 3

Step-by-step explanation:

$\dfrac{24}{r}=3\\\\24 = r*3\\\\\dfrac{24}{3}=r\\\\6 = r$ 6 is a solution.
