Answer:
x=3 and N is the mid-point.
Okay, so if N is the mid-point.
E D=15
E N=4 x -1
N D=4+ 2 x
6 x -3=15
Now get the 6 x by itself, so move the 3 over
So it would be: 6 x =18
So that would be 6 divided by 6 is x and then 18 divided by 6 equals 3
So, X equals 3
Answer:
26
Step-by-step explanation:
h represents highschool members
m represents middle school members
42 = h+m
h = 2m-6
Substitute h for 2m-6 in first equation:
42 = (2m-6)+m
Solve for m:
42 =3m-6
48 = 3m
m = 16
Subsitute 16 for m in second equation:
h = 2(16)-6
Solve for h:
h = 32-6
h = 26

If the gym is a square with 17 meters sides, its area is given (as any other square) by the square of the side:
So, the area of the classroom is
We can deduce the side of the classroom only assuming that it is a square as well: if this is the case, the side of a square with given area is the square root of the area, so we have
