Answer: Expression - 10.2x
The weight carried by each hiker is 10.2 pounds.
Explanation:
Hello! To find the answer, you have to add all of the weight together. Do 3.4 + 4.6 + 2.2 = 10.2. You know the total combined weight that all hikers will have to carry is 10.2 pounds. The expression will be 10.2x. You can check this by putting a random number in for x to represent the number of hikers. 10.2 (2) = 20.4. 20.4 would be the total weight that two hikers would have to carry, so the expression is correct. You already know the weight each hiker will have to carry, 10.2 pounds, so you can put that in for the second question.
