The formula for the average of n values would be:
(Value1 + Value2 + ... + Value n) ÷ n = Average
So the equation would be:
(83 + 80 + 85 + 77 + (5th grade)) ÷ 5 = 83
Let's rearrange to get the 5th grade. Multiply both sides by 5.
(83 + 80 + 85 + 77 + (5th grade)) = 83 * 5
Let's simplify both sides:
325 + 5th grade = 415
Then subtract 325 from both sides so that only the 5th grade would be left.
5th grade = 415 - 325
The 5th grade is 90.
(Value1 + Value2 + ... + Value n) ÷ n = Average
So the equation would be:
(83 + 80 + 85 + 77 + (5th grade)) ÷ 5 = 83
Let's rearrange to get the 5th grade. Multiply both sides by 5.
(83 + 80 + 85 + 77 + (5th grade)) = 83 * 5
Let's simplify both sides:
325 + 5th grade = 415
Then subtract 325 from both sides so that only the 5th grade would be left.
5th grade = 415 - 325
The 5th grade is 90.
for shorter solution, you simply
83 x 5= 415 - this includes the fifth grade
then
83 + 80 + 85 +77 = 325 - add the four grades
lastly,
415-325 = 90
83 x 5= 415 - this includes the fifth grade
then
83 + 80 + 85 +77 = 325 - add the four grades
lastly,
415-325 = 90
