We want to know how much time was spent practicing the guitar in week #3. We know the time in week #1 and week #2 and the total time. So, the amount of time in week #1 and week # 2 and week #3 will equal the total time. In a math sentence with all the practice times,

week 1 + week 2 + week 3 = total

$6\frac{1}{4} + 4\frac{2}{3} + ? = 15\frac{1}{3}$

? here represents what you don't know - and you could (if this were an algebra class) make that x. Our goal is to get the ? thing alone on one side and all the stuff on the other side.

$6\frac{1}{4} + 4\frac{2}{3} + ? = 15\frac{1}{3}$

$6\frac{3}{12} + 4\frac{8}{12} + ? = 15\frac{4}{12}$ by getting common demonimators. The lowest common denominator, or LCD, is 12.

$10\frac{11}{12} + ? = 15\frac{4}{12}$ by combining fraction parts with fraction parts and whole numbers with whole numbers

$? = 15\frac{4}{12} - 10\frac{11}{12}$ by subtracting $10\frac{11}{12} [\tex] from both sides[tex] ? = 14\frac{16}{12} - 10\frac{11}{12}$ by rewriting and borrowing from the whole number column and one being twelve over twelve.

$? = 4\frac{5}{12}$ by subtracting whole numbers from whole numbers and fractions from fractions

Therefore, he spent $4\frac{5}{12}$ hours practicing.

There is no graph but what i can say is that 1 is the slope and that -2 is the y- intercept

"it's not the heat, it's the humidity". that's a partly valid phrase you may have heard in the summer, but it's actually both. the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature. this has important considerations for the human body's comfort. when the body gets too hot, it begins to perspire or sweat to cool itself off. if the perspiration is not able to evaporate, the body cannot regulate its temperature. evaporation is a cooling process. when perspiration is evaporated off the body, it effectively reduces the body's temperature. when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases. in other words, the human body feels warmer in humid conditions. the opposite is true when the relative humidity decreases because the rate of perspiration increases. the body actually feels cooler in arid conditions. there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
