You are driving to visit a friend in another state who lives 440 miles away. You are driving 55 miles per hour and have already driven 275 miles. Write and solve an equation to find how much longer in hours you must drive to reach your destination. A. 55h + 275 = 440 ; h=3 B.55h - 275 = 440 ; h= 13 C.440h -275 = 55 ; h =0.75 D. 55h +275h = 440 ; h=1.3

A. 55h + 275 = 440; h=3

Step-by-step explanation:

Since all answer choices have a different H= , finding how many hours you have left to drive will give you the right answer.

You've already driven 275 miles in your 440 mile trio so you can subtract the 275 to find out how much you will still need to drive.

440 - 275 = 165

You already know that you are driving at 55 mph so divide 165 by 55 and the answer is three.

Option A was the only answer choice which listed h=3 so that is the correct answer.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

"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).
