To get your carpet cleaned in your house, easy-clean charges $50 cleaning fee plus $12 per room. write an equation

50+12r r=per room

Step-by-step explanation

50 is the flat fee that you pay for every time Easy-Clean cleans your house. Then they also charge you 12 dollars on top of that for the amount of rooms that they are cleaning.

So for example if you have 4 rooms in your house your equation would be

50+12(4)

12 times 4 is 48 so you would add 48 and 50 for to see how much you pay the cleaning company.

Hope this helps (:

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
