Daniel can paint a house in 10 days, while his father can paint the same house in 6 days. If they work together, how long will they finish the job? I need asap answer pl

3 days

Step-by-step explanation:

Let the amount of work be x.

Daniel:

10 days = x

1 day = x

Father:

6 days = x

1 day = x

Together:

1 day = x + x

        = x + x

        = x

        = x

No. of days = x ÷ x

                   = x × x

                   =

                   = 3

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

i think its a.

hope this
