  1. Warm Up Solve each equation. 1. y – 4 = 3x – 8, for x 2. m – hp = d, for p 3. A = ½bh, for h 4. S = C + xC, for x

  2. Consecutive Integers and Perimeter

  3. Objective • TSWBAT find consecutive integers with given sums and. • TSWBAT find perimeter of a figure.

  4. Define a Variable: to let a variable represent an unknown value. Define a variable, write an equation and solve. 1. The width of a rectangle is 2 cm less than its length. The perimeter of the rectangle is 16 cm. What is the length of the rectangle?

  5. Define a variable, write an equation and solve. 2. The width of a rectangle is 3 in. more than twice its length. The perimeter of the rectangle is 36 in. What is the width of the rectangle?

  6. Consecutive Integers: integers that differ by one. Example: Name four consecutive integers, if the first one is: 14? 29? 14, 15, 16, 17 29, 30, 31,32 n? - 17? n, n + 1, n + 2, n + 3 -17, -16, -15, -14

  7. The sum of three consecutive integers is 48. Find the integers.

  8. Consecutive Even/Odd Integers: integers that differ by two, the first being even/odd. Example: What’s the next four even integers if the first is: x? 22? x, x + 2, x + 4, x + 6 22, 24, 26, 28

  9. Consecutive Even/Odd Integers: integers that differ by two the first being even/odd. Example: What’s the next four odd integers if the first is: 13? n? n, n + 2, n + 4, n + 6 13, 15, 17, 19

  10. The sum of three consecutive even integers is 72. Find the integers.

  11. The sum of four consecutive odd integers is 136? Find the integers.
