![]() ![]() ![]() 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 $d$: College Board is committed to giving every student free access to the best test prep available. 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: Sample location Depth below water surface Water Rock core at a distance into cave wall of (m) adjacent to cave wall 2.0 cm 4.0 cm 6.0 cm 8.0 cm 13. 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. Something very helpful to realize in this question is that even though $b$ technically must be greater than $\frac$ False 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. Falvo believes that when trying something new it’s important to not overdo it. Similarly, when a fraction (less than 1) is taken to a negative power, the result will be greater than the original fraction. PSAT/NMST ANSWER EPLANATIONS READING 2 PSAT/NMSQT Practice Test 2 Reading Test Answer Explanations Question 1 Choice A is the best answer. Thus $b$ will be greater than $b^n$ when $n>1$. This is often a comprehensive and idealized collection of everything on the PSAT Math that a test taker should learn before the test.
