When you cannot directly plug in the given answer choices into an equation with variables, plug in random numbers (and make note of which variables are which numbers) to find the answer. Plugging in the answer choices is a good way to check your answers or solve the problem if you’re having trouble with the Algebra. While the solution can be found by isolating the variable that we are trying to find ( c in this case), we can also solve the question by seeing which values in the answer choices work and which don’t. If we divide each side by 1,000, we get c =.Since 10 3= 1,000 the equation can be rewritten as 450 = 1,000c.First we need to plug in 450 for f and 10 for d.Given f = cd 3, f = 450, and d = 10, what is c? If you’re having trouble finding the answer, plug in answer choices to see which value makes both sides of the equation equal each other. Plug in the answer you find with the question to check your work quickly. Questions with variables seem easy, but they’re also easy to make mistakes with. Tips on Concepts in the 2015 ACT Math Practice Test Plane Geometry and Trigonometry – 142 questions.Pre-Algebra and Elementary Algebra – 313 questions.Algebra and Coordinate Geometry – 448 questions.These questions break down into the following categories: Of those 1700 questions, 903 are math questions. now features about 1700 adaptive test prep questions for the ACT or the equivalent of nearly 8 full-length practice tests. So why not maximize your wins and get all the easy ones (for you) down first? :) All the questions are worth the same number of points. Skip difficult questions and come back later.Since you don’t get penalized for incorrect answers on the ACT (or the new SAT), eliminate as many choices as possible and make a guess! You might not know the correct answer but chances are you can eliminate a few obviously wrong ones. Plug in the answer choices to quickly check your work. With questions that ask you to solve variables, this is a quick way to make sure you didn’t make a silly mistake.Draw pictures when it gets confusing. Don’t be afraid to spend time organizing the picture of your thoughts, especially if it can prevent you from making silly mistakes and having to go back and figure out what’s wrong, which can take even more time.So keep powering through, and welcome, from Sarah Chou, Alex Young, and Michelle Lee! ACT Math Test General Strategies Hello! If you’re here, you’re definitely on your way to becoming a better ACT Test-taker, as well as improving your standardized testing abilities in general. ( Skip this guide and start working through the practice test with answer explanations) This post and the answer explanations on Piqosity were contributed by undergraduate students at Rice University as part of a project for their class BUSI 390. This post addresses the 60 questions in the Math section from the 2015-2016 ACT. Fortunately ACT makes freely available previously administered tests. Practice tests from third-party publishers like Kaplan or McGraw-Hill are just approximations. They are the only source for official, previously released exams. is the non-profit organization that administers the ACT college admissions test.
