The sum of three consecutive even integers is 72. Let x represent the first integer, x + 2 represent the second integer, and x +
4 represent the third integer. Which equation can be used to find the first integer? 3x + 6 = 72 3x = 2x + 6 2x + 64 = 72 3x + 72 = 2x + 6
1 answer:
Answer: 3x + 6 = 72
Step-by-step explanation: Three consecutive even integers can be represented as followed.
X → <em>first integer</em>
X + 2 → <em>second integer</em>
X + 4 → <em>third integer</em>
<em />
Since the sum of our three consecutive integer is 72, we can set up an equation to represent this.
X + X + 2 + X + 4 = 72
Now, we can simplify on the left.
3x + 6 = 72
Therefore, 3x + 6 = 72 would be the equation.

Sum of interior angles of a △ = 180°
∴ ∠T + ∠V + ∠U = 180°
⇒ 37° + 63° + X° = 180°
⇒ X° + 100 = 180°
⇒ X° = 180° - 100°
⇒ X° = 80° (D).
