Let x be the distance of the additional water stations from the starting line.
We want on that is 1.5 miles behind the 8-mile water station, and one that is 1.5 miles ahead. The following absolute value function describes x:
|x-1.5| = 8
Two numbers comply: x= 9.5 and 6.5.
The additional water stations will be 6.5 and 9.5 miles from the starting line.
Answer: 1.5
Step-by-step explanation:
The equation of a line in slope - intercept form is given as :
y = mx + c , where :
m = slope
c = y - intercept
Given:
2y = 3x - 30
What we need to do is to write it in slope - intercept form, we will make y the subject of formula.
Divide the equation through by 2
2y/2 = 3x/2 - 30/2
y = 3x/2 - 15
comparing with y = mx + c
slope = 3/2 = 1.5
He only asked students in his university and he stated that it represented the whole nation (his university does not represent the whole country.)

Answer:
Step-by-step explanation:
If we let v and b represent the seating capacity of vans and buses, respectively, then the two trips can be described by ...
8v +8b = 240
4v +b = 54
Dividing the first equation by 8 gives ...
v +b = 30
Subtracting that from the second equation gives ...
3v = 24
v = 8 . . . . . . . . . . . divide by 3
b = 30 -8 = 22
The number of students in each van is 8; the number in each bus is 22.
