Which algebraic expression represents "the difference of 54 and a number"?

The difference is the result of a subtraction problem.

We are given two values that are being subtracted: 54 and a number, represented by

So, represent this mathematically with .

54-x is the correct answer, the difference between number is x-54 or 54-x and the number of algebraic expressions subtracted or number symbol like x.

its a straight line parallel to the time axis

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
