Answer:

85

Step-by-step explanation:

You add 17 and 23 and you get 40 so 40=200 and divide 40 and 200 by 5 and so 1/40 =5 so 5x17=85.

sorry if I got it wrong I'm trying.

68 * 27 - 81 + ? = 600

tankabanditka [31]

The missing term is -1155.

Step-by-step explanation:

Given expression is

68 * 27 - 81 + ? = 600

Let the missing term be x

$68*27-81+x=600\\1836-81+x=600\\1755+x=600$

Subtracting 1755 from both sides

$1755-1755+x=600-1755\\x=-1155$

Therefore,

The missing term is -1155.
