20x20=400
pi(3.14) x 10^2(100)
100x3.14=314
400-100pi=85.8407 (then you can round if you need to)

105 student ID
Step-by-step explanation:
(it's a system)
4x+3y=615
x+y=180
(system as well)
4x+3y=615
x=180-y
4(180-y)+3y=615
720-4y+3y=615
-y=-105
y=105
x+105=180
x=180-105
x=75
The answer is 83, using the equation of 320-79-81-77=x and X is equal to 83
