Amara paid a one-time charge of $41.90 when subscribing to a movie rental service, and since then she has been paying $15.40 per month. So far she has paid $303.70. How many months has it been since Amara subscribed to the service?

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
