Answer:
3n+7=16
Step-by-step explanation:
3(3)+7=16
9+7=16
16=16
The second one is wrong(x=18)
3
Going up 7 and then down 4 can be represented by 7-4=3
Answer:
16/33
Step-by-step explanation:
The probability that the first ball is red and the second ball is black is:
8/12 × 4/11 = 8/33
The probability that the first ball is black and the second ball is red is:
4/12 × 8/11 = 8/33
So the total probability of drawing one ball of each color is 8/33 + 8/33 = 16/33.

Answer:
-1.17 volts
Step-by-step explanation:

-0.41 V - 0.76 V = -1.17 V
_____
Sometimes, when we talk about the difference, we mean the positive difference. If that is what is intended here, it is 1.17 volts.
