so hmmm on average on the last 7 test, you get 82, so hmmm we could say that on each of the 7 tests you got 82, so you got 82, 7 times.
now, let's say in the 8th test, you get a grade of "g", now, if we were to get an average of all 8 tests, that means the average will simply be (82*7) + "g", and we know that's 84, so
Sum :
Term : 1, and
Product : and
Factor : 5 and x, 3 and y, 9 and 5x+1
Quotient :
Coefficient : 5 is the coefficient of x and 3 is the coefficient of y.
Explanation:
The expression is
Sum: Sum is the result of addition of terms.
Thus, from the expression,
Sum =
Term : A term is a single number or a variable or a number multiplied with a variable.
Thus, from the expression,
Term = 1, and
Product : Product is the result of multiplication of numbers.
Thus, from the expression,
Product = and
Factor : The numbers that are multiplied is called a factor.
Thus, from the expression,
Factor = 5 and x, 3 and y, 9 and 5x+1
Quotient : Quotient is the result of dividing two numbers or variables.
Thus, the given whole expression is a quotient.
Hence, Quotient =
Coefficient : Coefficient of a variable is a number multiplied with a variable.
Thus, from the expression,
Coefficient : 5 is the coefficient of x and 3 is the coefficient of y.
