P.S Can I have brainliest?
New class average: 83
The original average: 82
And if there are 12 students, the total sum of all 12 tests should be
82 x 12 = 984
Then to find the average of the new tests
Add 12 points to the original sum
984+12 = 996
Then divide by 12 to find the new average
996/12 = 83
Hello from MrBillDoesMath!
Answer:
6
Discussion:
Let the unknown number called "x". Then the question states that
(7x -17) - 10 + 5 = 20 =>
7x + (-17 - 10 + 5) = 20 => as -17 -10 + 5 =-27 +5 = -22
7x -22 = 20 => add 22 to both sides
7x = 20 + 22 => 20 + 22 = 42
7x = 42 => divide both sides by 7
x = 42/7 = 6
Thank you,
