The successor of a certain number when added to twice the number produces 61. What is the number?

3 0

Lets see, If "n" represents the number, then "the successor of a certain number" is n+1. Now if "Twice the number" is 2n now for the expression "The successor of a certain number when added to twice the number" would then be 2n+n+1, which the problem stated is equal to 61 Therefore we can say that the correct option would be 2n+n+1=61

Which statement best explains the value of 17 - (-3)?

B) the additive inverse of -3 is +3, so 17-(-3) = 20 is your answer.

Remember, two negatives = one positive, and so:

- (-3) = 3

17 + 3 = 20
