x=20[vertically opposite angle are equal]
Answer:
.
Step-by-step explanation:
We have been given two sets as A: {71,73,79,83,87} B:{57,59,61,67}. We are asked to find the probability that both numbers are prime, if one number is selected at random from set A, and one number is selected at random from set B.
We can see that in set A, there is only one non-prime number that is 87 as it is divisible by 3.
So there are 4 prime number in set A and total numbers are 5.
We can see that in set B, there is only one non-prime number that is 57 as it is divisible by 3.
So there are 3 prime number in set B and total numbers are 4.
Now, we will multiply both probabilities to find the probability that both numbers are prime. We are multiplying probabilities because both events are independent.
Therefore, the probability that both numbers are prime would be .
2x + 8 = 16
2x = 16 - 8
2x = 8 (divide both sides by 2 to get x)
2x/2 = 8/2
x = 4
3x-26=10
3x=10+26
3x=36
X=12
Answer:
Step-by-step explanation:
Here we are given an equation in x and y and we are required to solve it for y
we have
subtracting 3x from each sides we get
now we divide both sides by 4 we get
Hence A) is our right answer.
