Tim and two of his friends were sharing an apartment and splitting the rent equally. If the rent costs x dollars per month, which expression describes how much Tim’s portion of the rent is?

(x/3)m

Step-by-step explanation:

Tim has to pay 1/3 of the rent per month

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.
