One day when terry went to school the temperature outside was –15 degrees fahrenheit. in terry's classroom the temperature was 68 degrees fahrenheit. how many more degrees was it inside the building than outside?
a. +83 degrees
b. +53 degrees
c. –83 degrees
d. –53 degrees

Well, to find the answer to this problem you have to change the -15 to a positive (+15) and add the two numbers together. And, 15 + 68 = +83 degrees.

So, your answer is: A. +83 degrees.

It's really easy because all your doing is changing the -15 to a positive 15 and adding the two numbers together to get your answer.

Hope I helped!

If you would like to know how many more degrees was it inside the building than outside, you can calculate this using the following step:

68 degrees Fahrenheit - (-15 degrees Fahrenheit) = 68 - (-15) = 68 + 15 = 83 degrees Fahrenheit

The correct result would be A. +83 degrees.

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
