Answer:
12 students
Step-by-step explanation:
1. 7s+16=100
We know the teacher has 100 markers, and she gave each student 7. If we say that s is the number of students, then 7s is the number of markers she gave out. We also know that she had 16 left over.
2. 7s+16-16=100-16
Subtract 16 from both sides of the equation.
3. 7s=84
Simplify the equation.
4. 7s/7=84/7
Divide both sides by 7.
5. Simplify the equation. Since s is the number of students, we now know how many students there are in the teacher's class.
The answer for this is D.

Answer:
Step-by-step explanation:
From the question we are told that
The relationship is ![\frac{150 }{d} = \frac{130}{c}](https://tex.z-dn.net/?f=%5Cfrac%7B150%20%7D%7Bd%7D%20%20%20%3D%20%5Cfrac%7B130%7D%7Bc%7D)
The number of fence post painted by chuck is
The number of fence post painted by Diana is ![k = 150](https://tex.z-dn.net/?f=k%20%3D%20%20150)
can paint 10 fences more than chuck so let say the of fence painted in an hour by chuck is ![g](https://tex.z-dn.net/?f=g)
Then the number of fence post painted by Diana in one hour is
![f = g+ 10](https://tex.z-dn.net/?f=f%20%3D%20%20g%2B%2010)
So
![\frac{150 }{ g + 10 } = \frac{130}{g}](https://tex.z-dn.net/?f=%5Cfrac%7B150%20%7D%7B%20g%20%2B%2010%20%7D%20%20%20%3D%20%5Cfrac%7B130%7D%7Bg%7D)
![130 g + 1300 = 150g](https://tex.z-dn.net/?f=130%20g%20%20%2B%201300%20%3D%20%20150g)
![g = 65 \ m](https://tex.z-dn.net/?f=g%20%3D%20%2065%20%5C%20%20m)
