Work out the value of x-y

x=5

y=3

Step-by-step explanation:

easy question to solve

y=21

x=35

Step-by-step explanation:

Y+X=56

y=56-X

X/Y=5/3

X=5y/x

Y=56-(5y/3)

y+5y/3=56

y=21

56-21=x

x=35

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.
