Answer:
87-88
Step-by-step explanation:
So, I assume that you mean 26 students times the teachers.
You can create two equations out of this information.
s = students while t = teachers
26t = s
900 - 9 = 891 seats being occupied
s + t = 891
You can use these two equations for substitution.
s = 891 - t
26t = 891 - t
27t = 891
t = 31
So, 31 teachers. Now plug that back into an original equation.
s + (31) = 891
s = 860
860 students.
Answer:
x = 7
Step-by-step explanation:
x + 4 > 2x - 3
x by itself = 1x
1x + 4 > 2x - 3
Subtract 1x
1x - 1x + 4 > 2x - 1x -3 =
4 > 1x -3
Add 3
4 + 3 > 1x -3 +3 =
7 > 1x
1x is the same as x
7 = x
