One painter can paint a room in 6 hours. another painter can paint the same room in 8 hours. how long would it take them to paint the room if they worked together?

7 hours

Step-by-step explanation:

If the painters split the work they have to do amognst each other {divide each by two}. Then add what you dived by two together that gives you 7 hours

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

if you was gonna solve for a, a is a   < -12
