Name: ________________________________ Date: _____________ Period: _______ Equations Tic-Tac-Toe MCC7.EE.3&4: Solve real-life and mathematical problems using numerical and algebraic expressions and equations. For each word problem, identify key words and write an equation. Solve each equation. Be sure to answer the questions. Three more than twice a number is fifteen. What is the number? A triangle has side lengths 2x – 1, 3x + 4, and x + 1. The perimeter of a triangle is 58 inches. What are the three side lengths? 5r + 7 = 42 3x + 4 2x - 1 x + 1 10(4x – 3) = 150 Find the perimeter of a square with the side length of 6x. Now, once you have found perimeter, SUBSTITUTE for X=3.
