Question #4543d

Answer 1

The current temperature is -5 degrees Celsius.

Explanation:

Method 1)
A more visual way to help one's understanding.
5 degrees Celsius minus 10 equals to -5. Here is the visual representation. Look at the number line below and count all the lines down from 5 (excluding the number itself) this leads up to -5. You will see that you have counted 10 lines (5 to 0, then 0 to -5 this means you counted 10 lines) - which proves 5 - 10 equals -5.

Method 2)
A much easier way.
5 - 10 = -5

Answer 2

Another way of looking at it.

`-5`

Explanation:

If the temperature dropped then the final temperature is less than we started so we need to reduce the `color(blue)(5)` by `color(brown)( 10)`

so we have `color(blue)(5)color(brown)(-10)`

Split the `color(brown)(-10)" into "color(brown)(-5-5)`

So`" "color(blue)(5)color(brown)(-5-5)" " =" " 0color(brown)( -5)`

So`" " 5-10=-5`
