Help!! I have no clue

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

“ 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 .
