The mean score is the average.
Let x=score in third game:
Average=(score 1st game + score 2nd game +x)/3 Multiply each side by 3.
(3)(Average)=(score 1st game + score 2nd game +x) Put in values.
(3)(51)=60+50+x
153=110+x Subtract 110 from each side.
43=x ANSWER: They scored 43 points in the third game.
.
CHECK:
Average is 51:
51=(60+50+43)/3
51=153/3
51=51
