-6/7p+1/7 um Idk what you wanted me to do but I added -4/7p with -2/7p
He now has 3 points I believe
One way to do this is use the fact that the exterior angles of all polygons add up to 360 degrees
So an exterior angle of a regular octagon = 360 / 8 = 45 degrees.
So each interior angle = 180 - 45 = 135 degrees
so total measure of all angles in octagon = 8 * 135 = 1080 degrees
Idk what you mean but maybe try stating it differently
Let the number of boys be x
Let the number of girls be y
x＝y＋5
3y＝2x＋12
3y＝2(y＋5)＋12
y＝22
3×22＝2x＋12
x＝27
(x, y)＝(27, 22)
There are 27 boys and 22 girls.
Hope my answer helped u :)
