The sum of all angles in a triangle = 180°, so: y°+y°+O=180°,==> 2y°+O=180°
Let's calculate O (angle NOP). We notice that O is the supplement of 120°
That mean O = 180°-120° = 60°. Now let's go back to 2y°+O=180
2y° + 60° = 180° ==> 2y° = 120° & y° = 60°

H + c = 456
c = 3h
h + 3h = 456
4h = 456
h = 456/4
h = 114 <=== hamburgers sold
c = 3h
c = 3(114)
c = 342......cheeseburgers sold
Answer:
-4
Step-by-step explanation:
3.4+2(9.7-4.8x)=61.2
2(9.7-4.8x)=61.2-3.4
2(9.7-4.8x)=57.8
9.7-4.8x=57.8/2
9.7-4.8x=28.9
4.8x=9.7-28.9
4.8x=-19.2
x=-19.2/4.8
x=-4
