A.-30
B. -6
C.6
D. 30

Answer 1

C

Explanation:

Noting that

+ (- ) is equivalent to subtraction

- (- ) is equivalent to addition

Given

13 + (- 12) - (- 5)

= 13 - 12 + 5

= 1 + 5

= 6 → C

Answer 2

C) 6

Explanation:

13 + (-12) - (-5) = 13 + (-12) + 5

= 1 +5

= 6

13 & (-12 ) have different sign, so subtract and put the sign of the greater number's sign.
