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.
Answer:
15.12
Step-by-step explanation:
4.20 x 3.60 = 15.12
In the problem it is already given that Anna had made 400 quart of lemonade. Now she poured them into smaller containers. each container had the capacity to hold 4/7 of a quart. It is required to find out the number of containers required to hold the full 400 quart of lemonade.
Then,
4/7 quart of lemonade can be filled in = 1 container
400 quart of lemonade can be filled in = [(7/4) * 400] containers
= 700 containers
So 700 containers having the capacity to hold 7/4 quart is required to hold a total of 400 quart of lemonade made.
