Answer:
Each student gets 2 1/3
Step-by-step explanation:
So you would divide 7 by 3, which you can't...so 6 divided by 3 is 2, and when you split the last one into thirds you can each have 1/3. Add the sections together, and each person gets 2 1/3
x = -3
36(x + 4) = 36
Divide both sides by 36
x + 4 = 1
Subtraact 4 from both sides
total degrees of a line is 180
4x+20+60=180
4x=100
X=25
