( {x}^{2} +  {y}^{2}  + 2xy + 1)dy = (x + y)dx \\  \frac{dy}{dx}  =  \frac{x + y}{ {x}^{2} +  {y}^{2} + 2xy + 1 }

Two-thirds of a number decreased by three is five equation form​
enot [183]

Answer:

2/3x - 3 = 5

Step-by-step explanation:

Let x be the number

2/3x - 3 = 5

Add 3 to each side

2/3x-3+3 = 5+3

2/3x = 8

Multiply each side by 3/2

3/2*2/3x = 8*3/2

x = 12

Will give medal to best answer!
mart [117]
We have two sides and one angle opposite to one of the known sides.

Begin with applying the Law of Sines to find angle A:
\frac{sin A }{a} = <span>\frac{sin C }{c}

Then, solve for sin A:
</span>sin A = \frac{a sinC}{c}

Now, plug in numbers:
sin A = 19 × sin(38) / 10 = 1.17

We know that it does not exist an angle whose sin is bigger than 1, therefore
no triangle is formed.
