Answer:
18 - (-12)
Step-by-step explanation:
Final temp. - Initial temp. = the change in temperature
By -12, we're indicating that is below zero (which is obvious) meaning that it is not in the "normal" scale nor in the imaginary scale of numbers. So, we can operate the following...
18 - (-12) = 30
So the temperature changed by 30 values or the temperature increased by 30 values, because the number is positive.
Since there are 675 students in a school and the canteen is giving 100 free apples to all the students, therefore, one student will receive less than one apple.
One student will receive 
part of an apple.
This information can be further interpreted as a percentage by doing the following calculation:
Thus, we can say that one student receives 14.81% of an apple. (Note that 100% represents one full apple).
Y= -2x/5 + 11/5

Answer:
1/2
Step-by-step explanation:
The slope is given by
m = (y2-y1)/(x2-x1)
= (6 - -1)/(12 - -2)
= (6+1)/(12+2)
7/14
1/2
