Answer:
OPTION A: Divide both the sides by 5
Step-by-step explanation:
We are given: 5z - 3 = 12
When we add 9 to both sides we get:
5z - 3 + 9 = 12 + 9
⇒ 5z + 6 = 21
⇒ 5z = 21 - 6 = 15
⇒ 5z = 15
To find the value of z we have to divide both the sides by 5.
i.e., 
⇒ z = 3.
If you ask 100 people and 60 say they are students, then you would assume that 60/100 people in town as a whole are students. To estimate the non-student population, you would infer that the other 40 are not students, thus making the non-student to student ratio 40:60 or 2:3 when simplified. This means that for every 2 non-students, there are 3 students. If we multiply 2000 by this 2:3 ratio, we would see that 2/3*2000 = the non-student population.The non-student population is estimated at 1,333.
