![]() But we're dividing by a positive number, so this is going to be l is greater than orĮqual to 14 over three. Greater than or equal to would turn to less than or equal to. If you're dividing by a negative number you would swap the inequality. And if you divide both sides by three, you're not going to change the sign. And then we are going to be left with, we're going to be left with three l on the left-hand side is greater than or equal This six and this sixĪre going to add to zero. And the best way we canĭo that is we can add six. So the first thing we might wanna do, is let's get rid of So let's see what we can do to get just an l on the left-hand side. They said l on one side,Īnd is greater than or equal to, actually all of these choices are greater than orĮqual to something else. Which of the following bestĭescribes the solutions to the inequality shown above? So it's three times l minus six is greater than or equal to eight. Minus six is greater than or equal to eight. This brings us to the final simplified statement that l is greater than or equal to 14/3. 3l/3=l, but we also need to change the other side: 14 divided by 3 equals 14 thirds, or 14/3. Because of this, we need to divide it by 3. It is to make the left side nothing but l, and it's currently 3l. Our goal is not to make nothing added to l on the left. Some questions may have multiple correct answers if so, bubble in only one. Now SADMEP has only one thing left to do that will bring us to our answer. Test Difficulty: Average Time Spent: 9 hrs 47. 8+6=14, so the equation is now "3l is greater than or equal to 14". We added 6 on the left, so we now need to add 6 on the right, which currently contains an 8.

However, as I said earlier, we need to change on the right what we changed on the left. We want to get rid of that 6, so we need to add 6, because -6+6 is 0, and no one cares about zeros, so the left side is now just 3l.

To score your test, use these instructions and the conversion tables and answer key at the end of this document. There is, however, a negative number, giving us the chance to add. Scoring Your SAT Practice Test 6 Congratulations on completing an SAT practice test. However, the left side is 3l-6, so there are no positive numbers. If the side containing l had any positive numbers, we would subtract their value, thus turning the left side into 3l+0, eliminating that number that is now a zero from the left side and thus making it 3l. ![]() There's nothing to subtract, because we want just l on the left side and just a number on the right. Now, in the case of this equation, let's do SADMEP. If you add 3 to one side, then 13=10, and it simply doesn't work that way, so you need to make the same change to the other side as well, so 13=13, because it does. However, when you make a change, you want to change both sides of the equation to keep it the same. In the case of changing both sides of an equation, you do it in the opposite order, aka SADMEP. First you simplify anything with Parantheses, then Exponents, then Multiplication or Division, and finally Addition or Subtraction. You've probably heard of PEMDAS, which is the order of operations in what to do in solving multistep problems. ![]() The goal is to isolate l and find what it must be greater than or equal to while still keeping the equation the same by changing things on both sides to make it clear what l is greater than or equal to. The table above shows some values of linear function \(g(x)\).I'll try and explain why he took the steps he did:įirst of all, the equation is that 3 times l, minus 6, is greater than or equal to 8. ![]() Which of the following is the sum of the two polynomials shown above?
