The sum of three numbers is 24. twice the smallest number is 2 less than the largest number, and the largest number is equal to the sum of the other two. what are the three numbers? c. the perimeter of a triangle

x + y + z = 24

z - 2 = 2x

z = x + y

So as z = x + y then we can substitute z in the first equation. This makes the first equation something like 2z = 24 and z = 12.

Now if z = 12 we can find x from the second equation. And x comes out to be 5 if we solve it.

Now finally y comes out to be 7 as z is equal to x + y.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

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.
