Describe the error in solving for one of the variables in the linear system 4.2 + 3y = 8 and 2 - 2y = -13 Х
4x + 3y = 8
x - 2y= -13 Multiply by -4.
4x + 3y=8
-4x+8y= -13
11y= -5
-5
y=
11

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .

8 < i think

hope this !

arc length = radius * x ( in radians)

6 * pi = 18 * x

divide by 18 on each side

6 pi / 18 = x

pi/3 = x

the angle is pi / 3 radians

or   60 degrees
