A puppy weighs 5.5 pounds when it was born. It gained an average of 0.8 pound per week for x weeks, and it currently weights 8.7 pounds. A puppy weighs 5.5 pounds when it was born. It gained an average of 0.8 pound per week for x weeks, and it currently weights 8.7 pounds. A turtle is 8.7 inches long, which is 0.8 inch longer than 5.5 times the length of a beetle.

Answer 1

The equation \(0.8x + 5.5 = 8.7\) could represent the situation about the puppy.

In this context:

• The puppy starts at a weight of 5.5 pounds (the initial weight).
• The puppy gains 0.8 pounds per week for \(x\) weeks.
• The total weight after \(x\) weeks is 8.7 pounds.

Thus, for each week the puppy gains 0.8 pounds, which, when added to the initial weight of 5.5 pounds, results in its current weight of 8.7 pounds.

So the correct interpretation of the equation is:
A puppy weighs 5.5 pounds when it was born. It gained an average of 0.8 pound per week for x weeks, and it currently weighs 8.7 pounds.
