<span>x -1÷8 = 20 :

x - 1 / 8 = 20 ( multiply both sides by 8 ) :

x * 8 - 1/8 * 8 = 20 * 8

Refine:

8 x - 1 = 160 ( add 1 to both sides : )

8 x - 1 + 1 = 160 + 1

8 x = 161

Divide both sides by 8 :

8 x /8 = 161/8

x = 161 / 8 decimal = 20.125

hope this helps!

First, multiply each side by 8 to get x-1=160, then add one to each side to get x=161. So, in conclusion, x=161! Hope this helped!

The point (-3,3) lies on a circle. What is the length of the radius of this circle if the center is located at (10,6) ?

Amiraneli [1.4K]

The radius is from center to point on a circle.
So your task is count distance between two points: S(10,6) and A(-3,3).
Distance between two points A(x1, y1) and B(x2, y2) count from this formula:
$|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\ \\ \hbox{So:} \\ \\ r=|SA|=\sqrt{(-3-10)^2+(3-6)^2}=\sqrt{(-13)^2+(-3)^2}=\sqrt{169+9}= \\ r= \sqrt{178}$
