For 7A)
The sum of -4 can not be both positive as from the set of rules (+)(+) can only make postive and -4 is decleared as negative
For 7B)
The sum of -4 can not be both negative as both negative (-)(-) is equivalent to a positive and the integer is -4 meaning it can not be negative
The reasonable answer to this would be two different numbers
It could be negative and positive
Or positive and negative
Nothing else

Step-by-step explanation:
Missing question: Determine the distanced covered by Mary.
Solution:
Mary: 3 mph
Jerry: 4 mph
Jerry starts jogging after Mary had been walking for 15 minutes.
Distance Mary had walked before Jerry starts jogging = Speed * Time = 3*15/60 = 0.75 miles.
Time taken by Jerry to jog for 2 miles = Distance/Speed = 2/4 =1/2 = 0.5 hrs.
Since they stopped at the same time,
Distance Mary walked while Jerry jogged = Speed* Time = 3*0.5 = 1.5 miles
Therefore,
Total distance Mary walked = 0.75+1.5 = 2.25 miles.
Answer:
(1c times 9/5) +32
That is the way to figure out °1c as 33.8°

Answer:
58+40e−t/2458+40e−t/24
step by step explanation:
Normally, the temperature of a corpse is the temperature of the surrounding environment.
This is done by losing or gaining heat to equilibrate to that of the surrounding.
Let's assume that the final temperature of the corpse is after t hrs.
Then the temperature of the surrounding in degree Fahrenheit is equal to 58+40e−t/2458+40e−t/24
