Answer: 3 hours
Step-by-step explanation:
Here is the correct question:
Betty and karen have been hired to paint the houses in a new development. Working together the women can paint a house in two thirds the time that it takes karen working alone. Betty takes 6 hours to paint a house alone. How long does it take karen to paint a house working alone?
Since Betty takes 6 hours to paint a house alone, that means she can paint 1/6 of the house in 1 hour.
Karen can also paint 1/x in 1 hour
Both of them will paint the house in 3/2 hours.
We then add them together which gives:
1/6 + 1/x = 3/2x
The lowest common multiple is 6x
1x/6x + 6/6x = 9/6x
We then leave out the denominators
1x + 6 = 9
x = 9 - 6
x = 3
Karen working alone will paint a house in 3 hours.

Step-by-step explanation:
15 5/8 divided by 5
First, we turn the 15 5/8 to a mixed number: 8 * 15 + 5 = 125/8
125/8 divided by 5/1 (which is equal to 5)
Next, we do Keep Change Flip.
Keep 125/8 the same, change the division to multiplication, and turn the 5/1 to 1/5.
1 * 125 = 125
8 * 5 = 40
Then, we get 125/40 = 3 5/40 BUT WAIT
We can reduce it once more! Divide 40 by 5
Each friend collected 3 1/8 bags of food.
A
x=75°
B
We know that ∠EFG=∠ABF because they are corresponding angles.
We also know that ∠x+∠ABF=180, because angles along a straight line always equal 180:
x+105=180
x=75°
