Answer:
The value of the expression is 57 :D
Step-by-step explanation:
Since x = -14 and y = 3, we need to replace the variables with the given numbers:
-4(x) - y + 4 =
-4(-14) - 3 + 4 =
56 - 3 + 4 =
53 + 4 = 57

The probability that a face card can be drawn from a standard deck of cards is 12/52 which can be simplified into 3/13.
The expected value is the product of the probability and the value.
Expected value = (3/13)($1) = $0.23
The difference between the amount spent and the expected value is equal to $0.27.
Answer:10 presents fell off
Step-by-step explanation: to find 2/6 we can start with finding 1/6 because it’s easier. To do that we divide 30 by 6 which equals 5. because 5 is 1/6 5x2 is 2/6 so the answer is 10
So first, we want to substitute in 15 to all the x variables.
So,
3x - 8y = 5
Becomes
3 * 15 - 8y = 5
Or,
45 - 8y = 5
So here, you can subtract 45 from both sides to move all like terms to one side.
-8y = 5 - 45
And then simplify:
-8y = -40
Then divide both sides by -8
y = 5
