Answer:
3 days
Step-by-step explanation:
Three hens lay 3 eggs in 3 days
We have to find the days in which 7 hens lay 7 eggs
Hen/egg=
Hen/egg=1
Using unitary method
1 hen lays 1 egg in 3 days
1 hen lays in 1 day =eggs
7 hens lay 7/3 eggs in 1 day
7 hens lay 1 egg=days
7 hens lay 7 eggs=
7 hens lay 7 eggs=3 days
Hence, 7 hens lay 7 eggs in 3 days

Answer:
≈11.4
Step-by-step explanation:
We know that, Ryan lives 2 blocks west and 5 blocks south of Devin
=> Coordinate of Ryan: (-2,-5). Because:
- 2 blocks west = 2 unit to the left = -2
- 5 blocks south = 5 unit go down= -5
Andy lives 7 blocks east and 2 block north of Devin.
=>Coordinate of Andy: (7,2), because:
- 7 blocks east = 7 unit ti the right = 7
- 2 block north = 2 unit go up = 2
Hence, to find out the distance of Ryan and Andy, we use distance formula as below:
≈11.4
