Marilyn and Gene are painting a room. Marilyn can paint it in 1 hour less time than Gene. Together they can do the job in 4 hours. How long will it take Gene if he works alone? Give your answer to the nearest tenth

Gene can take 0.8 hours to complete work

Step-by-step explanation:

Gene can paint a room in x hours

We are given that Marilyn can paint it in 1 hour less time than Gene

Marilyn can paint a room in (x-1) hours

Gene 1 hour work =

So,

General equation :

Formula :

x=0.812,0.0446

So, Gene can take 0.8 hours to complete work

(3x-8) or (3x+8)

step-by-step explanation:

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
