n → smaller

20 - n → larger

4 (20 - n) = 5n - 1

80 - 4n = 5n - 1

81 = 9n

n = 9

20 - n = 11

Therefore, the numbers are 9 and 11.

Your larger number is 11 and your smaller one is 9. You solve this by first dividing 20 in half. Then you make one larger than the other by subtracting 1 from one 10 and adding adding that subtracted 1 to the other 10. Then you multiply 11 by 4 (11×4) and get 44 then multiply 9 by 5 (9×5) and get 45. Then subtract 44 from 45 (45-44) and the difference is 1.

What is the greatest common factor of theses variables
DerKrebs [107]
B is the answer!

Explanation:
m^2 n^2 fits into both, you can take m^2 n^2 out of it both.

m is a common factor since you can take m out of both but it’s not the greatest common factor.

2n & 2m wouldn’t even be a common factor bc there is no 2n or 2m in neither.

The answer to the problem
larisa86 [58]

She puts 8% of her salary in, so multiply her pay by 8% to get her yearly amount she saves:

45000 x 0.08 = $3,600 per year.

The company puts 6% of that in the account:

3600 x 0.06 = $216

So per year 3600 + 216 = $3,816 is saved.

3,816 x 2 = $7,632 is the 2 year total.

The answer is A.
