ok so first step is to get rid of x
than you want to subtract x from 4/5x
than you want to minus 7 from 9 and you get 2
now times 5 to both sides like like this
4/5x5 and 2x5=
4x=10
x=2.5
i hope this helps you
then you have 
so then you will have

Answer:
option (A)
central angle = 0.375 rad
Step-by-step explanation:
Given in the question,
radius of the circle = 8 inches
arc of the circle = 3 inches
To find,
measure of a central angle
Central angles are subtended by an arc between those two points.
Formula to use:
<h3> s = (r) (θ)</h3>
<em>where r = radius </em>
<em> s = arc length </em>
<em> θ = angle in radians</em>
<em />
Plug in the values in the equation
<h3>3 = (8) (θ)</h3><h3>θ = 3/8 </h3><h3>0.375 rad</h3>
