Answer:
125
Step-by-step explanation:
A full circle is 360°
80+85+70=235
360-235=125
179 students in 3rd grade, 189 4th graders, and 209 5th graders. 577 students total!
Since both equations are equal to y, we can just combine them like this:
1/3x-3=-x+5
1/3x=-x+8
4/3x=8 (since x is 1x which is 3/3x)
x=6
Plug x back in:
y=-6+5
y=-1
So x=6 and y=-1
Hope this helped!
