Answer:
B) 14
Step-by-step explanation:
1/5 + 1/3 = x (don't worry, it's not algebra, I'm just using x as an example)
The common denominator is 15, so you multiply 5 by 3 = 15 and 1 by 3 = 3,
3/15 = 1/5
Then, multiply 3 by 5 = 15 and then 1 by 5 = 5, so it's
5/15 = 1/3
5/15 + 3/15 = 8/15 and then multiply 15 by 2 = 30 (number of students) and because you multiplied 15 by 2, you also multiply 8 by 2 = 16
So it is now 16/30, so you do 30-16 which is 14.
14 students chose Station M (doesn't sound like a good station).
Whoo! Let's go! (I'll stop being cringy now).

Answer:
A) 3y = x + 16
Step-by-step explanation:
The equation of a perpendicular line can be found by swapping the x- and y-coefficients and negating one of them. The constant will be chosen to match the given point.
Swapping coefficients, we get ...
-3y = x + c
Negating the y-coefficient gives ...
3y = x + c
Filling in the given point, we have ...
3(5) = -1 + c
16 = c
The equation of the perpendicular line can be written as ...
3y = x + 16 . . . . matches choice A
_____
Note that choice A is the only equation that gives a line with positive slope. The given equation has negative slope, so its perpendicular must have positive slope.
