The number of hours needed to paint a house varies inversely with the number of painters working. a 2400 square foot house can be painted in 27 hours by 6 painters. how many painters would it take to paint the house in 18 hours? i know the formula is y=k/x but i know y is the hours, but don't know what k and x should be. and show you work. merci beaucoup!

Write it all out on a piece of paper and it will be way easier  

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
