The combined weight of 2 identical dice, 5 identical balls and 4 identical marbles was 260 grams. The combined weight of one die and one marble was 55 grams. And 3 balls weighed the same as two dice. What was the total weight (in grams) of one die, one ball, and one marble?

The total weight of one die, one ball, and one marble is 75 grams.

Step-by-step explanation:

Consider the provided information.

Let d represents the number of dice, b represents the number of balls and m represents the number of marbles.

So according to the question.

The combined weight of 2 identical dice, 5 identical balls and 4 identical marbles was 260 grams.

 ....(1)

The combined weight of one die and one marble was 55 grams.

 ....(2)

3 balls weighed the same as two dice.

Multiply both sides by 5 and divide by 3.

 .....(3)

Now put the value of equation 2 and 3 in equation 1.

Put d=30 in equation 2.

Put d=30 in equation 3.

The total weight (in grams) of one die, one ball, and one marble is:

The total weight of one die, one ball, and one marble is 75 grams.

54/3 is 18 so 18 is your answer
