![]() ![]() ![]() ![]() Solving this set of equations is made easier if we divide both sides of the second equation by $10$. We now have a system of two simultaneous equations that we can use to solve for $s$ and $d$: We can combine this information to get the following equation: Renting the dancing room for $d$ minutes cost $20d$. Renting the singing room for s minutes cost $10s$. We also know that the total cost was $\$600$. We know that together the rooms were rented for a total of 48 minutes: Let $s$ be the number of minutes the singing room was rented, and let $d$ be the number of minutes the dancing room was rented. In each portion, no-calculator and calculator, you’ll first see multiple-choice questions and then student-produced response. On the test, questions from the areas are mixed together, requiring you to solve diferent types of problems as you progress. It also helps assess readiness for the SAT and identifies areas to focus on for score improvement. Something very helpful to realize in this question is that even though $b$ technically must be greater than $\frac$ False In the previous chapters, you learned about the four areas covered by the SAT Math Test. A: Taking the Digital PSAT/NMSQT provides the opportunity to get accustomed to the digital SAT format, reduce test anxiety, and manage time better on the test day. Using these facts, you can conclude that the correct choice is (A).Īn alternative approach is to find a value of $b$ that can be used to test each of the four answer choices. The text begins by noting that Anne reveled in the world of color about herthat is, she takes great delight in colorful things. Similarly, when a fraction (less than 1) is taken to a negative power, the result will be greater than the original fraction. 5 PSAT/NMSQT PRACTICE TEST 1 ANSWER EXPLANATIONS QUESTION 6 Choice D is the best answer because it most accurately describes the main purpose of the text. Thus $b$ will be greater than $b^n$ when $n>1$. Use the fact that multiplying a fraction (less than 1) by itself will make the result smaller each time. ![]()
