The ages of three friends are consecutive integers. if the sum of the three
friends' ages is 45, which equation below can be used to determine the age, x,
of the youngest friend?

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

Step-by-step explanation:

consecutive integers means 1 right after the otherwith 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 = 45but since I cant see ur answer choices, it could also be : 3x + 3 = 45
