X divide by -2
this is your formula
x/ (-2)
It will be written like <span>log (base b) N = x . </span>
A) No, because your bag has 8 marbles, and each time you take it out, you put it back in. So there is a chance that you can pick the same marble again, and not pick up a red marble that's already in the bag.
b) No, because you could still keep on picking up the same marble over and over again.
c) There is no absolutely certain number of times.
The sum of interior of all angles in a triangle = 180
Given 3 angles = <span>80°, 2x + 2°, and 5x°
To find x:
</span><span>80°+ 2x + 2 + 5x = 180
7x + 82 = 180
7x = 98
x = 14
answer
x = 14 </span>
