Answer:

x=11

Step-by-step explanation:

The angles given are alternate exterior angles and alternate exterior angles are equal if the lines are parallel

5x+9 = 6x-2

Subtract 5x from each side

5x+9-5x = 6x-2-5x

9 = x-2

Add 2 to each side

9+2 =x-2+2

11=x

Now,

5x + 9 ( vertically opposite angle )

Then,

5x + 9 = 6x - 2 ( corresponding angle )

x = 11

I hope you understand...

What is an equivalent to -16m^2n-(-25m^2n)+(-7m^2n)

pantera1 [17]

Answer:

The equivalent expression is:

$-16m^2n-\left(-25m^2n\right)+\left(-7m^2n\right)=2m^2n$

Step-by-step explanation:

Given the expression

$-16m^2n-\left(-25m^2n\right)+\left(-7m^2n\right)$

$\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a,\:-\left(-a\right)=a$

$=-16m^2n+25m^2n-7m^2n$

$\mathrm{Add\:similar\:elements:}\:-16m^2n+25m^2n-7m^2n=2m^2n$

$=2m^2n$

Therefore, the equivalent expression is:

$-16m^2n-\left(-25m^2n\right)+\left(-7m^2n\right)=2m^2n$
