Answer:
8 in
Step-by-step explanation:
Given,
Diameter ( circle ) = 16 in ( from the diagram )
To find : Radius ( circle ) = ?
Formula : -
Radius ( circle ) = Diameter ( circle ) / 2
Radius ( circle )
= 16 / 2
= 8 in
Use a system of equations.
(x=# of small dogs, y=# of big dogs)
x+y=9 (times by -5) -5x-5y=-45
5x+8y=51
Then add the equations together and the x's cancel.
3y=6
y=2
So he walked 2 big dogs and 7 little dogs.
