What is the solution to the equation 5=2/5a​

a = 25/2

Step-by-step explanation:

5 = (2/5)*a // - (2/5)*a

5-((2/5)*a) = 0

(-2/5)*a+5 = 0

5-2/5*a = 0 // - 5

-2/5*a = -5 // : -2/5

a = -5/(-2/5)

a = 25/2

a = 25/2

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,

step-by-step explanation:

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.
