ATITEAS 7 MATH EXAM RECENTLY UPDATED 2023 WITH COMPLETE SOLUTIONS 1. Simplify the following expression: 2x + 4y - 3x - 2y Solution: 2x - 3x + 4y - 2y = -x + 2y 2. If a recipe calls for 2 1/2 cups of flour, and you want to make 1/2 of the recipe, how much flour do you need? Solution: To make 1/2 of the recipe, you need half the amount of flour, which is: (1/2) x 2 1/2 cups = 1 1/4 cups 3. Solve for x: 2(x + 5) = 12 Solution: First, distribute the 2: 2x + 10 = 12 Then, subtract ...
