Math Problem Statement

solve the problem with the use of polya's four step problem solving procedures. The sum of three consecutive odd integers is 27. Find the three integers.

Solution

To solve the problem using Polya's four-step problem-solving method, we will proceed as follows:

Problem Statement:

The problem is to find three consecutive odd integers such that their sum is 27.

Step 1: Understand the Problem

We need to find three consecutive odd integers. Let's define these integers:

  • Let the first odd integer be xx.
  • The next consecutive odd integer will be x+2x + 2.
  • The third consecutive odd integer will be x+4x + 4.

The problem states that their sum is equal to 27: x+(x+2)+(x+4)=27x + (x + 2) + (x + 4) = 27

Step 2: Devise a Plan

Our plan is to set up an equation based on the sum of these integers and then solve for xx. Once we find xx, we'll substitute it to find all three integers.

Step 3: Carry Out the Plan

Let's simplify the equation: x+(x+2)+(x+4)=27x + (x + 2) + (x + 4) = 27 Combine like terms: 3x+6=273x + 6 = 27 Subtract 6 from both sides: 3x=213x = 21 Divide by 3: x=7x = 7

Now, substitute x=7x = 7 into the expressions for the three integers:

  • First integer: 77
  • Second integer: 7+2=97 + 2 = 9
  • Third integer: 7+4=117 + 4 = 11

Step 4: Look Back (Check the Solution)

To verify the solution, we check if the sum of these integers is indeed 27: 7+9+11=277 + 9 + 11 = 27 The solution is correct.

Solution

The three consecutive odd integers are 77, 99, and 1111.
