Identify what Number Property is shown for each Statement: ( ASAP 20 Points ) 21 = 21

8 • 1/8 = 1

19 • 1 = 19

4 + 0 = 4

If 11 = y then y = 11

7 + 4 = 4 + 7

2 + (-2) = 0

10 • 3 = 3 • 10

If k = 15 and 15 = 3m, then k = 3m

9 • 0 = 0

(6 + 2) + 1 = 6 + (2 + 1)

(5 • 3) • 4 = 5 • (3 • 4)

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 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.

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared
