Answer:
x = 5 and y = 1 is the answer.
Step-by-step explanation:
(-5)(x+4y=1)
(-4)(-3x-5y=-10)
-5x + -20y = -5
12x + 20y = 40
———————
7x + 0 = 35
7x= 35
7x/7 = 35/7
x = 5
subtitution:
x= 5
x + 4y = 1
5 + 4y = 1
4y = 1 - 5
4y = 4
4y/4 = 4/4
y = 1
Answer: 20.77%
Step-by-step explanation:
There are 52 cards in a standard deck. Out of these cards, there are 12 face cards. Thus, the probability of drawing a face is 12/52.
On a 20-sided dice, there are 20 options of numbers to roll. Out of these 20 numbers, 18 of the numbers are greater than or equal to 3, making the probability 18/20, or 9/10.
To find the probability of two events, you need to multiply the probabilities together. Thus, you need to multiply 12/52 by 9/10.
(12/52) * (9/10) = 27/130
27/130 is about equal to 0.2077, or a 20.77% probability.
