HELPP!! Please help! Marking brainliest!

Work Shown:

(5 yellow)/(6 red) = (x yellow)/(9 red)

5/6 = x/9

5*9 = 6*x

45 = 6x

6x = 45

x = 45/6

x = (15*3)/(2*3)

x = 15/2

x = 7.5

You need 7.5 quarts of yellow paint if you want to mix with 9 quarts of red.

Note: the decimal 7.5 is the same as the mixed number 7 & 1/2.

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.
