Answer:
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.
