Question

Carl is boarding a plane. He has 2 checked bags of equal weight and a backpack that weighs 4kg. The total weight of Carl's baggage is 35kg
Write an equation to determine the weight, w, of each of Carl's checked bags.

Answer 1

Answer:

Step-by-step explanation:

Let weight of each bag of Carl be 'w'

He has 2 bags of same weight.

Thus weight of 2 bags is 2w

Weight of bagpack is 4kg.

Total weight of bags is 35kg.

A.T.Q. 2w + 4 = 35

Hence this is the equation to find the weight of checked bags of carl. On further solving

2w = 35 - 4

2w = 31

w = 31/2 = 15.5kg

Thus weight of each bag is which is 15.5kg.

Answer 2

Answer:

15.5

Step-by-step explanation:

let weight of one Carl is w

let weight of other Carl is w'

we know that weights are equal So we can write w=w'=W and w+w'=W+W=2W

because weights are equal

we can say that weight of Carl equal to 2w kg

weight of backpack is 4 kg

let it equals to x

and weight of Carl's and backpack are equal to 35

so we get an equation to find the weight of each carl

2W+x=35

2W+4=35

2W=35-4

2W=31

W=31/2

W=15.5Kg
