Answer:
5 days.
Step-by-step explanation:
We are told that one person has 3 dogs and each dog eats 2 pounds of food in one day.
Let us find amount of food needed for 3 dogs in 1 day by multiplying number of dogs (3) by amount of food eaten by one dog (2 pounds).


Now let us divide 30 by 6 to find the number of days available food will last.

Therefore, 30-pound bag of dog food will last for 5 days.
Move the x over to the other side
2y=10-5x
Divide both sides by 2 to get the y alone
y=-5/2x+5
Find m from the equation of a line (y=mx+b)
m=-5/2
Slope=-5/2
