Creating Equations

Consecutive Number Problems If the numbers are consecutive use: 1st number = x 2nd number = x + 1 3rd number = x + 2 etc

Consecutive Number Problems If the numbers are consecutive ODD: 1st number = x 2nd number = x + 2 3rd number = x + 4 etc

Consecutive Number Problems If the numbers are consecutive EVEN: 1st number = x 2nd number = x + 2 3rd number = x + 4 etc

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

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

Example 3 You and 3 friends divide the proceeds of a garage sale equally. The garage sale earned $412. How much money did you receive? $103 each

Example 4 The length of a rectangle is 6 cm. more than the width. The perimeter is 32 cm. Find the dimensions. 11 cm. by 5 cm.
