cindy and candy are task to clean their house cindy and candy can finish cleaning the house in 2hrs if it takes cindy working alone 3hrs longer than it takes candy working alone how many hours will each finish working

The time it takes Candy working alone to finish cleaning the house is 3 hours

The time it takes Cindy working alone to finish cleaning the house is 6 hours

Step-by-step explanation:

The given parameters are;

The time it takes Cindy and Candy to finish cleaning the house = 2 hrs

The time it takes Cindy working alone to finish cleaning the house = 3 hrs + The time it takes Candy working alone to finish cleaning the house

Let x represent the time in hours, it takes Candy working alone to finish cleaning the house

∴ The time, in hours, it takes Cindy working alone to finish cleaning the house = 3 + x

2/x  + 2/(3 + x)  = 1

(2·(3 + x) + 2·x)/x·(3 + x) = 1

(2·(3 + x) + 2·x) = x·(3 + x)

6 + 2·x + 2·x = 3·x + x²

6 + 4·x = 3·x + x²

x² + 3·x - 4·x - 6 = 0

x² - x - 6 = 0

(x - 3)·(x + 2) = 0

x = 3, or x = -2

Therefore, it takes Candy, x = 3 hours working alone to finish cleaning the house, and it takes Cindy 3 + x = 3 + 3 = 6 hours working alone to finish cleaning the house.

The time it takes Candy working alone to finish cleaning the house = 3 hours

The time it takes Cindy working alone to finish cleaning the house = 6 hours

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
