Answer:

Step-by-step explanation:

Let the consecutive integers be (x - 1), x, (x + x)

x - 1 + x + x + 1 = 45

3x = 45    ---------> this is the equation

x = 45/3

x = 15

The ages are 14,15,16

Answer:

Step-by-step explanation:

consecutive integers means 1 right after the other....with x being the youngest, then x + 1 being the second friend, and x + 2 being the third friend.

so ur equation would be : x + x + 1 + x + 2 = 45......but since I cant see ur answer choices, it could also be : 3x + 3 = 45
