The positive two-digit integers x and y have the same digits, but in reverse order. which of the following must be a factor of x y

(a) 6
(b) 9
(c) 10
(d) 11
(e) 14

(D) 11

Step-by-step explanation:

Let the first digit x composed of ab and the second digit y composed of reversed of ab =ba

The sum of x and y will be

x+y = ab+ ba

x+y= (10.a + b) + (10.b +a)

x+y= 10a+b+10b+a

x+y= 11a+11b

By factorization

x+y= 11(a+b)

Therefore 11 is compulsory factor of x and y

answer: the answer is 127 degrees

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
