Respuesta :

Answer:

7 and 8

Step-by-step explanation:

Given The sum of two consecutive integers is at least 14.

Let the two consecutive digits be x and x+1

The condition that should be satisfied by these numbers is that their sum must be atleast 14.

[tex]x+(x+1)\geq 14[/tex]

[tex]2x+1\geq 14[/tex]

[tex]2x\geq 13[/tex]

[tex]x\geq \frac{13}{2}[/tex]

[tex]x\geq 6.5[/tex]

Since x is an integer x=7 and the other digit is 8.
