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