Step-by-step explanation:
7x+3(-2)=14
7x-3x2=14
7x-6=14
(7x-6)+6=14+6
7x-6+6=20
7x=20
7x/7 = 20/7
x= 20/7 or 2.85714285714

He owes 120 $ all you have to do is multiple 60 and 20 and you will get your answer hope I helped
This is a arithmetic sequence, so all we need to do is subtract the numbers and find the common difference.
40 - 24 = 16
56 - 40 = 16
72 - 56 = 16
Therefore, the common difference is 16.
Best of Luck!
Answer:
LCM of 3, 5, and 6 is the smallest number among all common multiples of 3, 5, and 6. The first few multiples of 3, 5, and 6 are (3, 6, 9, 12, 15 . . .), (5, 10, 15, 20, 25 . . .), and (6, 12, 18, 24, 30 . . .) respectively. There are 3 commonly used methods to find LCM of 3, 5, 6 - by division method, by prime factorization, and by listing multiples.
Step-by-step explanation:
Answer: No, this is not necessarily evidence that the proportion of Americans who are afraid to fly has increased.
Step-by-step explanation:
Since we have given that
n = 1400
x = 154
So, 
and p = 0.10
So, hypothesis would be
So, the test statistic value would be
At 5% level of significance,
critical value would be 1.96.
Since 1.96>1.25.
so, we will accept the null hypothesis.
Hence, no, this is not necessarily evidence that the proportion of Americans who are afraid to fly has increased.
