Studdy Solution

STEP 1

What is this asking? How much does the temperature need to increase to go from 18-18°C to 6-6°C? Watch out! Don't get tricked by the negative numbers!
We're looking for the *difference* in temperature, which is always positive.

STEP 2

1. Visualize the Thermometer
2. Calculate the Temperature Change

STEP 3

Imagine the thermometer!
We're starting at a chilly 18-18°C.
Brrr! We want to warm things up to 6-6°C, which is still cold, but definitely better!

STEP 4

We're moving *up* the thermometer, so the temperature is *increasing*.
Even though we're dealing with negative numbers, the change is positive!

STEP 5

We can find the change by subtracting the **initial temperature** from the **final temperature**.
So, we have (6)(18)(-6) - (-18).

STEP 6

Remember, subtracting a negative number is the same as adding its positive counterpart.
So, (6)(18)(-6) - (-18) becomes (6)+18(-6) + 18.

STEP 7

Now, we have (6)+18(-6) + 18.
We can think of this as adding to zero.
We have 6-6, so we need 66 to get to zero.
That leaves us with 186=1218 - 6 = 12.

STEP 8

So, (6)+18=12(-6) + 18 = 12.
The temperature increased by 12\textbf{12}°C.

STEP 9

The temperature increased by 12\textbf{12}°C.
