Ricardo is considering two monthly plans a dog-walking service offers. Plan 1 charges $3 per walk plus $10 for grooming at the end of each month. Plan 2 charges $5 per walk and then offers free grooming at the end of each month. Part A. Enter an equation to model the number of walks, w, when the two plans cost the same amount. Part B. How many walks will it take for the two plans to cost Ricardo the same amount?

the least common denominator is 40

step-by-step explanation:

1. the cylinder is a. 54

2.   a.108 /

a and c

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
