We can set this problem up as an algebraic equation, which we can then solve to find our answer.
We start at -3. So we can start our equation with that:
However, this doesn't represent any change in temperature, just that we start at -3. To show change, we will use the variable 
, where stands for the number of hours. Each hour accounts for a change of -2.5 in degrees, meaning that we must multiply our by -2.5. We can now add this term into our equation:
We are trying to find when we will reach -18 degrees, so we will set our entire equation equal to -18 and solve:
It will take us 6 hours, or choice A.
The answer is 8234 because if you calculated you will get that answer
1. X=41
2. x=17
3. x=25
4. x=81
Hope that helps
Answer: 25%
Step-by-step explanation:
We know that the whole are split into 4 pieces, that is why they are called fourths.
Vide the number 1 by 4 for 4 pieces.
1 vide by 4 = 25%
