  1. Warm up • Five times the sum of a number and two • Twelve subtracted from three times a number • Seven more than twice a number 5(x + 2) 3x – 12 2x + 7

  2. Review HW

  3. Creating Equations

  4. Consecutive Number Problems • If the numbers are consecutive use: • 1st number = x • 2ndnumber = x + 1 • 3rdnumber = x + 2 • etc

  5. Consecutive Number Problems • If the numbers are consecutive ODD: • 1stnumber = x • 2ndnumber = x + 2 • 3rdnumber = x + 4 • etc

  6. Consecutive Number Problems • If the numbers are consecutive EVEN: • 1stnumber = x • 2ndnumber = x + 2 • 3rdnumber = x + 4 • etc

  7. Example 1 • The sum of 3 consecutive even numbers add up to 1002. Find the three numbers. 1st 332 2nd 334 3rd 336

  8. Example 2 • The sum of 4 consecutive numbers add up to 4810. Find the four numbers. 1st 1201 2nd 1202 3rd 1203 4th 1204
