Question

the sum of 3 consecutive integers is 30. find the number​

Answer 1

Answer:

The three consecutive integers whose sum is 30 are 8, 10, and 12. Explanation: Let the three consectuive integers be x, x + 2, and x + 4.

Step-by-step explanation:

You can make an equation x + (x+2) +(x + 4) = 30. Then by combining like items, you get 3x + 6 = 30. Then solve, 3x = 30 - 6; then 3x = 24, and x = 8. So the 3 numbers are 8, 10 and 12.

Answer 2

Step-by-step explanation:

• Let the three consecutive integers be x, ( x+1) , ( x + 2)

• Sum of integers = 30

x + x +1+ x +2 = 30

3x +3 = 30

3x = 30-3

3x = 27

x = 27/3

x = 9

• Therefore, three integers are 9, 10, 11

• CHECK

9 + 10 + 11 = 30
