Answer:
First = 1251
Second = 1260
Third = 1268
Step-by-step explanation:
First: 9x
Second: 9(x+1)
Third: 9(x+2)
[tex]{ \tt{first + second = 2511}} \\ { \tt{9x + 9(x + 1) = 2511}} \\ { \tt{9x + 9x + 9 = 2511}} \\ { \tt{18x = 2502}} \\ { \tt{x = 139}}[/tex]
First = 9 × 139 = 1251
First = 9 × 139 = 1251Second = 9(139 + 1) = 1260
First = 9 × 139 = 1251Second = 9(139 + 1) = 1260Third = 9(139 + 2) = 1268
