For this case we must simplify the following expression:
We eliminate the parentheses taking into account that:
So:
We add similar terms taking into account that:
Equal signs are added and the same sign is placed.
Different signs are subtracted and the major sign is placed.

Answer: 36/121
Step-by-step explanation:
There are 6 red marbles out of total 11.
The probability of drswing two red marbles is 6/11 x 6x11 = 36/121
1. Make y the subject of the equation
y = -4 - 6x
2. Substitute values for guess and check
8 = -4 - (6 x 2)
8 = -4 - 12
This is incorrect.
2 = -4 - (6 x 1)
2 = -4 -6
This is incorrect.
-10 = -4 - (6 x 1)
-10 = -4 -6
This is correct.
The correct answer is C.
Answer:
684 Hours.
Step-by-step explanation:
If the plane travelled that distance in 5 hours, then all you need to do is divide the distance by 5 to get the distance travelled in one hour. This is obviously presuming that the speed travelled was constant or that this is an average figure.
3420/5 = 684.
