Answer:
Each bag of dog food weighs 2 pounds
Explanation:
Here is the complete question:
Four bags of dry dog food plus 9.5 pounds of dry cat food weigh 17.5 pounds in all. How many pounds does each bag of dog food weigh?
Explanation:
From the question,
Four bags of dry dog food plus 9.5 pounds of dry cat food weigh 17.5 pounds in all.
Let the weight of one bag of dry dog food be x.
Then we can write that
4x + 9.5 pounds = 17.5 pounds
To determine x, subtract 9.5 pounds from both sides
4x + 9.5 pounds - 9.5 pounds = 17.5 pounds - 9.5 pounds
4x + 0 = 8 pounds
4x = 8 pounds
Divide both sides by 4
4x/4 = 8 pounds/4
x = 2 pounds
∴ The weight of one bag of dry dog food is 2 pounds.
Hence, each bag of dog food weighs 2 pounds.
