Answer:

Converse: If line x and y are parallel then angles on the same line are supplementary angles.

Step-by-step explanation:

<em><u>Converse:</u></em>

Let's start with the converse, so if line x and y are parallel then angles on the same line are supplementary angles. I'm not sure if that's the converse your teacher wants but my teacher taught me this.

<em><u>Finding x:</u></em>

Now we know that the angles are supplementary angles, that means if w add them together we get 180°. So our equation will be $10x-22+3x+7=180$ . Now we just solve it. We start by combining like terms, then adding the 15 to both sides, and lastly we divide the 13 to both sides and get...

$10x-22+3x+7=180\\13x-15=180\\13x=195\\x=15$

x=15

Simplify the expression given below 1/2x^2-4x-2/x

Alex787 [66]

Answer:

We need to simplify the following expressio:

$\frac{1}{2} x^{2}- 4x-\frac{2}{x}$

Multiply the whole expression by '2x':

$x^{3}-8x^{2}-4$

The expression can't be more simplified.
