Given,

HK is the perpendicular bisector of GJ. So, GK = KJ.
GK = 2x + 10
KJ = 3x - 15

_______________

Find KJ .

_______________

First find the value of x

$\sf \: GK \: = KJ \\\sf 2x + 10 = 3x - 15 \\\sf 2x - 3x = - 15 - 10 \\ \sf - x = - 25 \\ \sf \: - > \boxed{\bf \: x = 25}$

Now, find the value of KJ.

$\sf3x - 15 \\ \sf= 3(25) - 15 \\ \sf=7 5 - 15 \\ = \boxed{\bf \: 60}$

-> The value of KJ is 60.

What is 36 percent of 210?

ohaa [14]

Hey there!

Let's start by finding what 1% of 210 is.

This can be done by dividing 210 by 100, since 1% is the same as 1/100 of something.

210 ÷ 100 = 2.1

To find 36%, we can multiply 2.1 by 36.

2.1 x 36 = 75.6

So, 36% of 201 is 75.6.

Hope this helps!

What is the solution to the system of equations y= -3x+6 and y =9

Lilit [14]

Plug the value of 9 in for y
9=-3x+6

Subtract 6 from both sides
3=-3x

Divide both sides by -3
-1=x

Final answer: x=–1
