Jill has four of her five game scores: 8,6,6,3
Her average score for the five games is 6 points. What is the fifth game score?
5 * 6 = 30
30 - 23 = ?
(8+6+6+3+x)divide by 2 = 6
so 8+6+6+3=23
then 23+x/2=6
6 multiply by 2= 23+x
12=23+x
x= -11
i think it can be positive anwser
(8+6+6+3+x)divide by 5 = 6
so 8+6+6+3=23
then 23+x/5=6
6 multiply by 5= 23+x
30=23+x
x= 7
sorry that is not wrong my mistake
To find the fifth game score, we can use the formula for average which is:
Average = (Sum of all scores) / (Number of scores)
Since we know the average score is 6 points for the five games, we can substitute the values we know into the formula:
6 = (Sum of all scores) / 5
To find the sum of all scores, we can add up the four scores that we know:
Sum of all scores = 8 + 6 + 6 + 3 = 23
Now we can substitute the sum of all scores into the formula:
6 = 23 / 5
To find the fifth game score, we can multiply both sides of the equation by 5:
6 * 5 = 23
The fifth game score is 30 - 23 = 7 points.
Therefore, Jill's fifth game score is 7 points.
