9. Solve the equation for x.
3x + y = 2
Z

x= 2/3 -1/3y or x= -1/3y + 2/3

Step-by-step explanation:

3x + y= 2 (subtract the y to get 3x by itself)

3x= 2-y (divide both sides by 3 to get x by itself)

x= 2/3 - 1/3y

step-by-step explanation:

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
