Answer:
m∠BOC = 53°
Step-by-step explanation:
The definition of an angle bisector is that it divides an angle into two congruent angles. ∠AOC is divided by angle bisector OB into angles ∠AOB and ∠BOC, hence those two angles are congruent.
m∠AOB = m∠BOC = 53°
Answer:
3
Step-by-step explanation:
2×-3y = 12 ( multiply whit 4)
3x + 4y =1 (multiply whit 3 )
8x -12y =48
9X+ 12y = 3
if you add this equations
17X =51
X= 51 / 17
x=3
Answer: It's proportional
Step-by-step explanation: For every 0.5 Storage space (GB), you can fit 100 songs.
You can solve this by using 8!
when you put this through a calculator, you'll get 40320.
Therefore, eight boxes can be arranged in 40,320 different ways on a shelf.
