Carl is boarding a plane. he has 2 checked bags of equal weight and a backpack that weighs 4 kg. the total weight of carl's baggage is 35 kg.

write an equation to determine the weight, w, of each of carl's checked bags.

Carl has 3 bags in total. One backpack weighs 4 kg and the rest two checking bags have the equal weight. The total weight of 3 bags is given to be 35 kg.

Let the weight of each checking bag is w kg. So we can write:

2 x (Weight of a checking bag) + Weight of Backpack = 35

Using the values, we get:

2w+ 4 = 35

Using this equation we can find the weight of each checking bag, as shown below.

2w = 31

w = 31/2

w = 15.5

Thus, the weight of each checking bag is 15.5 kg

38 dollars is your answer.
