Tonya dog- walking service charges a flat rate of $20 per month, plus $3 per mile that each dog is walked. beth does not charge a monthly fee for her dog- walking service , but she charges $5 per mile that each dog is walked. find the miles for which tonya and beth will charge the same amount.

Given that Tonya charges 20$ monthly fee and 3$ per mile of her dog-walking service.

And Beth does not charge any monthly fee but charges 5$ per mile of the dog walked in.

Let x be the number of miles dog has walked in a month.

The amount Tonya will charge on x miles = fixed monthly fee + number of miles * charge per mile = 20+3x

And the amount Beth will charge on x miles = 0+ 5*x = 5x.

We are asked to find the x-value for which Beth chargeable amount = Tonya chargeable amount

That is 5x = 20+3x

            5x-2x = 20

              2x=20

                x=

Hence number of miles for which Tonya and Beth will charge the same amount is 10.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

what graph
