Answer:45 * t = 2.5 * (1-t)...the equation will have one solution.
Step-by-step explanation:
For this case, the first thing you should know is:
d: v * t
Where,
d: distance
v: speed
t: time
To go to school by bus we have:
d = 45 * t
To return from school we have:
d = 2.5 * (1-t)
how the distance is the same:45 * t = 2.5 * (1-t)
Hello!
We know that from midnight to 6am the temperature went up 8° and at 6am it was -21°
To find what it was at midnight we have to work backwards
Since it went up we have to subtract 8 from -21
-21 - 8 = -29
The answer is -29°C
Hope this helps!
