Answer:

  (6.2, 4.5)

Step-by-step explanation:

That point (P) will be the weighted average of the end points, where each weight is the proportion of the segment at the end farthest from the point:

  P = (3A +1B)/(3+1)

  = (3·7.5 +2.3, 3·4.2 +5.4)/4

  = (24.8, 18)/4

  = (6.2, 4.5)

grandymaker [24]

Let the number of days be x.

Jameer paints 1 wall in 3 days. In 1 day, he paints 1/3 of a wall. In x days, he paints (1/3)x walls.

June paints 2 walls in 5 days. In 1 day, she paints 2/5 of a wall. In x days, she paints (2/5)x walls.

Working together, in x days they paint (1/3)x + (2/5)x walls.

We want to know the number of days they will take to paint 10 walls, so we let the expression equal 10.

(1/3)x + (2/5)x = 10

(5/15)x + (6/15)x = 10

(11/15)x = 10

x = 10 * 15/11

x = 150/11

It will take 150/11 days which is the same as 13.6363... days or approximately 13.6 days.
