Answer 2

16

Answer 3

@Tennis5518 What does it mean "to drop" ? It means that it will decrease, right ? So if I decrease 31 by 15, or in math language 31-15, how much do I get ?

Answer 4

16 but it integers

Answer 5

@Rosemarybaldwin7 got it right !

Answer 6

@Tennis5518 16 degrees F is the correct answer.
What do you mean by "it integers" ?

Answer 7

well if theyre not asking you to write it in a fraction or a decimal then 16 is right.

Answer 8

16 is an integer

Answer 9

yes 16 is an integer

Answer 10

can someone summary it?

Answer 11

summarize what? how you did it?

Answer 12

Summary : Suppose the temperature now is \[x^{O}F\]
If it's going to DROP by
\[a ^{O}F\]
then the temperature will be
\[\left( x-a \right)^{O}F\]
If it's going to RAISE by
\[a ^{O}F\]
then the temperature will be
\[\left( x+a \right)^{O}F\]

Answer 13

Like can you summarize how you got the answer @marinos

Answer 14

@Tennis5518 Now, the temperature is 31 degrees. The radio said it will drop by 15. This just means to do the substraction of the two numbers, in order to get the new tempearature, i.e. 31-15=16 degrees
Is it clear now ?

Answer 15

yes
