Kate and Jean paint a house together in 6 days. If they work alone, Kate takes 5 fewer days than Jean would take to do the same job. Which equation represents the time it takes Kate to paint the house by herself? A. X^2-7x-30=0 B. X^2-5x-6=0 C. 2x-1=0 D. X^2-5x/6=0

Step-by-step explanation:

Let x = Time taken (in days) by Jean to do the job.

Then, Time taken by Kate to do the job = x-5

Then, together they will take time (t) as

.

Since it is given that Kate and Jean paint a house together in 6 days.

i.e.

So, the equation represents the time it takes Kate to paint the house by herself is .
