but it stands for 3.14

Point N is called the centroid of the triangle.

To solve this problem, start with the smallest and call it n. The next three numbers are n+1 and n+2, so the sum of these numbers is:

n +(n+1) + (n+2) = 126.

This equation reduces to:

3n+3 = 126 subtracting 3 from either side makes it

3n = 123 and dividing either side by 3 means

n = 41

The smallest is 41 so the largest is 43

1) The number must be greater than at least 14. This is because the limit is 14 years older.

let Ishaan = y, Christopher = x. Set the system of equation

y = 3x

y = x + 14

Set the two equations equal to each other

3x = x + 14

Simplify. Note the equal sign, what you do to one side, you do to the other. Isolate the variable

3x (-x) = x (-x) + 14

3x - x = 14

2x = 14

(2x)/2 = (14)/2

x = 14/2

x = 7

**Christopher is 7 years old, **Ishaan is 21 years old.

__Check: __

7 x 3 = 21 (True)

7 + 14 = 21 (True)
