Answer:
1
Step-by-step explanation:
If there isn't a number in front of a variable then always assume is is one.
For example, look at this equation:
x + 3y = 16
See how there is no number in front of the x?
It can't be 0 in front of the x because 0 times anything is zero, right?
Therefore, it has to be a one.
So, the equation above could be written like this:
1x + 3y = 16
In mathematics it is just automatically assumed that if a term doesn't have a number in front of the variable, then the coefficient of that term is 1.

Answer:
B. 10/91
Step-by-step explanation:
Box has 5 red buttons and 9 blue buttons.
We add 5 and 9 to get the total buttons.
5 + 9 = 14
Then, we find the probability for a red button.
5/14 = .35
Now, that we've taken out 1 button.
The amount of buttons available changes.
14 - 1 = 13
There are 4 red buttons remaining.
The probability for a red button changes to 4/13.
4/13 = .30
Then, we multiply both probabilities.
.30 x .35 = .111
Convert to a fraction.
.111 = 10/91
Thus it would be B.
