How do I do this? 4m-9=m+7

4m-m=7+9

3m=16

m=16/3

m=5.9... or 6

Step-by-step explanation:

if you are finding "m" do that if not then idk

the "..." or you could out a "." on top of the "9" instead but it basically shows that it is a recurring decimal and you only write the "or 6 if you where asked to round off your answer if not don't write that part

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
