Answer:
11
Step-by-step explanation:
Given: 
Using PEDMAS rule to solve it.
Now, simplifying:
We first open parenthesis which is (-7) = -7
= 
Now, we evaluate the exponent which is 
Next, we divide -36 by 12 to get -3
=
Next, we multiply -2 and -7 to get 14
= 
Lastly, we add -3 and 14 to get 11
= 
∴ Answer is 11
A. Nancy has the greatest spread because her longest training time was 105 and her shortest being 82, making the spread 23, and Peter’s spread is only... Longest: 112 Shortest: 92 making it 20!
b. Nancy. Middle %50 would be Peter’s 110-92 making the spread 18, and Nancy’s spread is 93-90 making the spread making it 12
c. The spreads tell us they are very close to each other, and just Peter has more time but a less spread than Nancy.
30 is the answer
6*5\6 is 5
And 30 is needed to be multiplied y one to get five
