For this case we have that by definition:

$(a * b) * c = a * (b * c)$

Indicates an example of the associative property of multiplication.

$(6 * 5) * 4 = 6 * (5 * 4)\\30 * 4 = 6 * 20\\120 = 120$

Similarly, we observe the associative property of multiplication

zvonat [6]

Answer:
129 points
Step-by-step explanation:
Let L and C represent the scores of Luke and Caleb, respectively.
L = 2C -15 . . . . . Luke scored 15 less than twice the number Caleb did
L +C = 201 . . . . . they scored 201 points altogether
Add twice the second equation to the first:
2(L +C) + (L) = 2(201) + (2C -15)
3L +2C = 387 +2C . . . . simplify
3L = 387 . . . . . . . . . . . . .subtract 2C
L = 387/3 = 129 . . . . . . .divide by 3
Luke scored 129 points.
