Final answer:
Larry's score was 120 pins, Moe's score was 240 pins, and Curly's score was 230 pins.
Step-by-step explanation:
Let's denote Larry's score as L, Moe's score as M, and Curly's score as C.
We are given that Moe's score is the highest, and Larry's score is half of Moe's score, so L = 0.5M.
We are also given that Curly's score is 10 pins less than Moe's score, so C = M - 10.
The sum of their scores is 590, so L + M + C = 590.
Substituting the values for L and C in terms of M, we have:
0.5M + M + (M - 10) = 590
Combining like terms, we get 2.5M - 10 = 590.
Adding 10 to both sides and dividing by 2.5, we find M = 240.
Substituting this value back into the equations for L and C, we find L = 120 and C = 230.
Therefore, Larry's score was 120 pins, Moe's score was 240 pins, and Curly's score was 230 pins.
