Answer:
Step-by-step explanation:
Since you have an expression for y, it is convenient to use it.
-2x + 8(3x) = -22 . . . . . substitute 3x for y in the second equation
22x = -22 . . . . . simplify
x = -1 . . . . . . . . . .divide by 22
Substituting this value into the expression for y:
y = 3(-1) = -3
The solution is (x, y) = (-1, -3).

Probability is calculated by comparing the odds to a certain event occurring to the number of possible events.
P=

For example, take a six-sided dice number 1-6 on each side. The probability of rolling a 4 would be1 in 6 or 1/6. This is because of the six possible outcomes, rolling a 4 is only one of them.
P(4)=1/6
Now take the same dice. The probability of rolling an even number is 3/6. To see why, lets look at the total possible outcomes:
1
23
45
6
Of the 6 possibilities, 3 are even numbers.
P(even)=3/6 or 1/2
The answer is 6 days.
36/6=6
Hope this helps! :))
