21.) The sum of two consecutive integers is –49. Write an equation that models this situation and find the values of the two integers.


a.) n + n + 1 = –49; n = –24; n + 1 = –23


b.) n + n + 1 = –49; n = –25; n + 1 = –26


c.) n + n + 1 = –49; n = –25; n + 1 = –24


d.) n + 2n = –49; n = –17; 2n = –34

Answer:

a

Step-by-step explanation:

sum of two consecutive numbers examples:

1 + 2 = 3 or 8 + 9 = 17

therefore the equation should be n + n + 1 = -49

if n = -24, n + 1 = -23 since -24 + 1 is -23

-24 + -24 + 1 = -49
