Step-by-step explanation:
5x+1-1=3x+7-1
5x=3x+7-1
5x=3x+6
5x-3x=3x+6-3x
2x=3x+6-3x
2x = 6

Answer:
25000
Step-by-step explanation:
Let enrollment be represented by E.
E(1999) =
E(1999)=1.1E(1998) ............................equation 1
E(2000)= 0.08E(1999)+E(1999)
E(2000)=1.08E(1999)
enrollment in 2000, E(2000) is 29700.
29700 = 1.08E(1999)
E(1999) =29700/1.08
E(1999) =27500
from equation 1;
E(1999)=1.1E(1998)
27500 = 1.1E(1998)
E(1998) =27500/1.1
E(1998) = 25000
Enrollment in 1998 = 25000
Every interior angle of square is a right angle (90°)

5x - 10 = 90
5x = 90 + 10
5x = 100
x = 100/5
x = 20</span>
