Answer:

See below.

Step-by-step explanation:

13. D

Simply subtract. 85376 - 37793 = 47583.

14. C

[Something] - 32497 = 26348

Add 32497 to both sides:

[Something] - 32497 + 32497 = 26438 + 32497

[Something] = 58845

15. C

Compute each difference:

A: 51455 - 26478 = 24977

B: 49351 - 15274 = 34077

C: 63286 - 37439 = 25847

(D: 46307 - 21550 = 24757)

16. B

Simply subtract:

143864 - 112955 = 30909

17. A

First, find the difference:

85732 - 39864 = 45868

Only 45798 (A) is less than 45868.

(Note that B is equal to, not less than).

18. C

Subtract:

45932 - 29574 = 16358.

19. B

Subtract:

96834 - 31727 = 65107 - 12156 = 52951

20. C

27301 - 12352 - [Something] = 7356

14949 - [Something] = 7356

Add [Something] to each side:

14949 = 7356 + [Something]

Subtract 7356 from each side.

7593 = [Something]

Note: Do you need help with subtraction specifically? These questions can be solved with simply with a calculator, but perhaps that is not the intention here. Anyways, I recommend using Khan Academy to improve your arithmetic skills if necesary.
