INPUT ARTICLE: Article: Your heart rate fluctuates based on your activity. Even standing can elevate heart rate. So before you measure your heart rate, you need to allow yourself to “relax.”  A good way to find out your resting heart rate is to measure it immediately after waking up in the morning. Do not measure your heart rate after exercise as it can remain elevated and you won’t be able to get an accurate reading. Also, being stressed, anxious or upset can elevate your heart rate. Do not measure your heart rate after drinking caffeine or in a hot, humid environment as these might temporarily increase your heart rate. Use the tips of your middle and ring fingers to press down on (or palpate) the radial pulse on the inside of your wrist or on the side of your neck (your carotid artery). It might take you a moment to feel the pulsation and you might need to move your fingers around to find it. Count the number of beats in 30 seconds and multiply by two or in 10 seconds and multiply by six to get your heart rate per minute.  For example, if you counted 32 beats in 30 seconds, multiply that by two to get your resting heart rate of 64. Or, if you counted 10 beats in 10 seconds, multiply 10 by six to get a resting heart rate of 60. If your rhythm is irregular, count for a full minute. As you begin counting, start the first pulse felt as zero and the second pulse as one. Repeat the measure a few times to get a more accurate reading.

SUMMARY: Sit down and remain calm for a few minutes. Use your fingers to find your pulse. Push your fingers against the artery until you feel a strong pulsation. Count each beat or pulsation to find your rate per minute.

In one sentence, describe what the following article is about: Because the back of the postcard is exposed, anyone who picks up your postcard will be able to see what you have written. Avoid writing things that you wouldn’t tell a stranger, like personal bank information, intimate secrets, or anything that could be used to steal your identity. Keeping your writing on the left side of the postcard is very important in ensuring that the postcard makes it to its destination. Creeping into the address part of the postcard (the right side) could make the address difficult to read and could throw off the post office. If you have too much to write about, consider sending a letter in addition to the postcard. Keep the message short and brief on the card, and write a longer message in a letter. Write the return address on the top left of the postcard. If you plan to be travelling within a month of sending the postcard, write the return address of your next destination. Return addresses are best if you know exactly where you will be over time. Sloppy or illegible handwriting may result in the post office sending your postcard to the wrong place, or discarding because of bad handwriting. If you are worried about your handwriting, practice writing the address in print on scrap paper before transcribing it to the postcard. Be sure to write legibly for both the recipient address and the return address. The note itself does not have to be too neat, as long as your recipient can read it.
Summary: Do not write about anything too personal. Do not let your writing cross over to the right side of the postcard. Add a return address if you will be in one place for a while. Write legibly, especially with addresses.

INPUT ARTICLE: Article: The following terms will be used throughout the examples, and are common in problems involving algebraic fractions:   Numerator: The top part of a fraction (ie. (x+5)/(2x+3)).  Denominator: The bottom part of the fraction (ie. (x+5)/(2x+3)).  Common Denominator: This is a number that you can divide out of both the top and bottom of a fraction. For example, in the fraction 3/9, the common denominator is 3, since both numbers can be divided by 3.  Factor: One number that multiples to make another. For example, the factors of 15 are 1, 3, 5, and 15. The factors of 4 are 1, 2, and 4.  Simplified Equation: This involves removing all common factors and grouping similar variables together (5x + x = 6x) until you have the most basic form of a fraction, equation, or problem. If you cannot do anything more to the fraction, it is simplified. These are the exact same steps you will take to solve algebraic fractions.  Take the example, 15/35. In order to simplify a fraction, we need to find a common denominator. In this case, both numbers can be divided by five, so you can remove the 5 from the fraction:  15    →     5 * 335   →       5 * 7 Now you can cross out like terms. In this case you can cross out the two fives, leaving your simplified answer, 3/7. In the previous example, you could easily remove the 5 from 15, and the same principle applies to more complex expressions like, 15x – 5. Find a factor that both numbers have in common. Here, the answer is 5, since you can divide both 15x and -5 by the number five. Like before, remove the common factor and multiply it by what is “left.”15x – 5 = 5 * (3x – 1) To check your work, simply multiply the five back into the new expression – you will end up with the same numbers you started with. The same principle used in common fractions works for algebraic ones as well. This is the easiest way to simplify fractions while you work.  Take the fraction: (x+2)(x-3)(x+2)(x+10) Notice how the term (x+2) is common in both the numerator (top) and denominator (bottom). As such, you can remove it to simplify the algebraic fraction, just like you removed the 5 from 15/35:  (x+2)(x-3)    →     (x-3)(x+2)(x+10)   →       (x+10) This leaves us with our final answer: (x-3)/(x+10)

SUMMARY:
Know the vocabulary for algebraic fractions. Review how to solve simple fractions. Remove factors from algebraic expressions just like normal numbers. Know you can remove complex terms just like simple ones.
