Answer: 1.8x+32=y
1.8(25)+32=y = y=77
Explanation:
Since it is 1.8 times whatever the degree in celcius is, you can chose any variable to represent that number, I just chose x. You also need a variable to represent the end, which can be any variable, so I chose y. This way, if you needed to graph it, you could.
You would add 32 after you multiplied the degree in celcius by 1.8. So, that would be the equation: 1.8x+32=y (at least, I think)
Next, just plug in 25 for x, and you get 77 after solving.
Hope this helps + is right!
