A. Commutative Property
"The commutative property states that the order in which two numbers are added or multiplied does not affect the sum or product." ~ ck12.org
May I have brainliest please? :)
No because 2/5 equals 4/10, which is .4, not .25 :)

The sum of two numbers
x + y = 21
x = smaller number
y = larger number
Larger Number = y = (2x -6)
Substitute (2x - 6) for y
x + y = 21
x + (2x - 6) = 21
3x - 6 = 21
3x = 21 + 6
3x = 27
3x / 3 = 27 / 3
x = 9
Smaller number = x = 9
Find the larger number by inserting 9 into (2x - 6)
(2x - 6)
(2(9) - 6)
18 - 6
12
So
x = 9
y =12
Check our answer by inserting x = 9 and y = 12 into x + y = 21
x + y =21
9 + 12 = 21
21 = 21
So since we have 21 = 21 we know our answer is correct.
1l=1000=>x l=29000000=>x=29000000:1000=>x=29000
