Water boils at 100 degrees celsius or 212 degrees fahrenheit. Water freezes at 0 degrees celsius or 32 degrees fahrenheit. If the weather forecaster says it will be 25 degrees celsius today. write and solve a linear equation to find what fahrenheit temperature this is.

Answers

Answer:

given with two conditions: after 0 degrees Celsius, this is equal to 32 degrees Fahrenheit and after at 100 degrees Celsius, this is equal to 212 degrees Fahrenheit . We translate these into points, we have (0,32) and (100, 212). we get the slope of the points ((212-32)/100) or 9/5. we plug to the equation y-y1 = m (x-x1) where m is equal to 9/5. y-32 = 9/5 (x-0). Simplifying, we get y -32 = 9x/5 or equal to y = 9/5 x + 32 where x is degrees Celsius and y is degrees Fahrenheit.

The given temperature is required in Fahrenheit.

The required temperature is 77 degrees Fahrenheit.

Let the x axis denote Celsius

and y axis denote Fahrenheit

The ordered pairs are [tex](100,212)[/tex] and [tex](0,32)[/tex]

The equation of the line will be

[tex]y-212=\dfrac{32-212}{0-100}(x-100)\\\Rightarrow y-212=1.8(x-100)\\\Rightarrow y-212=1.8x-180\\\Rightarrow y=1.8x+32[/tex]

The temperature is 25 degrees Celsius so [tex]x=25[/tex]

[tex]y=1.8\times 25+32\\\Rightarrow y=77[/tex]

The required temperature is 77 degrees Fahrenheit.

question 3 is 25 because the median is the middle number, which in this case is 25. question 4 you got correct but there are multiple modes for this set of data being 22,31,46 because all of these numbers tie with 2 of them being repeated throughout the table. question 5 just shows that beth would be the oldest in the club by a marginal number too so that is why beth might not want to join the club.

Find the LCD to remove the lower number for each term

in this case 6 and 8 hhave a multiple of 24 so multiply everything by 24

Here’s a walk through for each term
5/6(24)

So first you can divide 24 by 6 which is 4, than multiply 4 by the higher number with gets 20

For -2 just multiply this by 24 since it’s not being divided
-2(24)=-48

For 7/8 divide 24 by 8 which gets you 3, than multiply this by 7 to get 21
