Answer: D 1800 degrees

Step-by-step explanation:

The sum of the interior angles can calculated by using the formula 180(n-2) where n is the number of sides of the shape. Plug 12 in for n and you'll get 1800 degrees which is the sum of all the interior angles in the polygon. Hope this helps :D

For this question we have to take LCM of the fractions to simplify it and process further. So, by LaTeX interpreter equation editor, Here we go.

$\mathbf{Least \: Common \: Multiplier: 3x}$

$\mathbf{\dfrac{2}{x} \times 3x + \dfrac{1}{3} \times 3x - \dfrac{4}{x} \times 3x}$

Combine the fractions to multiply the numerator.

$\mathbf{\dfrac{2 \times 3x}{x} + \dfrac{1 \times 3}{3}x = \dfrac{4 \times 3x}{x}}$

$\mathbf{\dfrac{6x}{x} + \dfrac{3}{3}x = \dfrac{12x}{x}}$

$\mathbf{6 + x = 12}$

Just subtract both of the current sides by the numbered value "6".

$\mathbf{6 + x - 6 = 12 - 6}$

$\boxed{\underline{\mathbf{Final \: \: Answer: \: x = 6}}}$

Hope it helps.

-1/2u + 3/5= 1/6. What is u?

cestrela7 [59]

So to start off on answering we are going to subtract 3/5 from both of the sides:
−1/2u+3/5−3/5=1/6−3/5
−1/2u=−13/30
Okay, so now we are going to multiply both sides by 2/(-1):
(2/−1)*(−1/2u)=(2/−1)*(−13/30)
The final answer shall be:
u=13/15
I hope this helps!
