Question

The sum of two consecutive integers is 59. Write an equation that models this situation and find the values of the two integers.

A.) n+n+1=59;n=30;n+1=31
B.) n+2n=59;n=19;2n=38
C.) n+n+1=59;n=29;n+1=28
D.) n+n+1=59;n=29;n+1=30

Answer 1

D) n + n + 1 = 59, n = 29, n + 1 = 30

Explanation:

Answer 2

An equation that models this situation: n + n +1 = 59 ( two consecutive integers: n, n+1 and their sum is 59)
2 n+1 = 59
2 n = 58
n = 58 : 2
n = 29, n + 1 = 30
Answer:D) n + n + 1 = 59, n = 29, n + 1 = 30
