At a picnic there were 3 times as many adults as children and twice as many women as men. If there was a total of x men, women, and children at the picnic, how many men were there, in terms of x?A. x/2
B. x/3
C. x/4
D. x/5
E. x/6

Answers

Answer 1

Answer:

Answer:

I believe the answer is c.) x=4

Step-by-step explanation:

I saw this on a webpage:

The moment we see “x,” we can consider picking numbers. The key here is contemplating how complicated the number should be. Swim with the current – let the question tell you. A quick look at the answer choices reveals that x could be something simple. Ultimately, we’re just dividing this value by 2, 3, 4, 5, or 6.

Keeping this in mind, let’s think about the first line of the question. If there are 3 times as many adults as children, and we’re keeping things simple, we can say that there are 3 adults and 1 child, for a total of 4 people. So, x = 4.

Now, we know that among our 3 adults, there are twice as many women as men. So let’s say there are 2 women and 1 man. Easy enough. In sum, we have 2 women, 1 man, and 1 child at this picnic, and a total of 4 people. The question is how many men are there? There’s just 1! So now we plug x = 4 into the answers and keep going until we find x = 1. Clearly x/4 will work, so C is our answer. The key was to let the question dictate our approach rather than trying to impose an approach on the question.

Answers

Answer:

$a_(n)$ = 3 - n

Step-by-step explanation:

There is a common difference between consecutive terms in the sequence, that is

1 - 2 = 0 - 1 = - 1 - 0 = - 1

This indicates the sequence is arithmetic with n th term

$a_(n)$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 2 and d = - 1 , thus

$a_(n)$ = 2 - 1(n - 1) = 2 - n + 1 = 3 - n

Solve for x: 3|2x − 2| + 6 = 18. x = 3, x = −3
x = 3, x = −1
x = 1, x = −1
x = −3, x = 1

Answers

Answer:

Option 2 - x = 3, x = −1

Step-by-step explanation:

Given : Expression $3|2x-2|+6= 18$

To find : Solve the expression ?

Solution :

The expression gives an absolute function which means $|a|=-a,a$

Expression $3|2x-2|+6= 18$

1) Taking $3(2x-2)+6= 18$

Solving,

$6x-6+6= 18$

$6x= 18$

$x=(18)/(6)$

$x=3$

2) Taking $3(-(2x-2))+6= 18$

Solving,

$3(-2x+2)+6= 18$

$-6x+6+6= 18$

$-6x+12=18$

$-6x=6$

$x=-(6)/(6)$

$x=-1$

Therefore, The solution of $3|2x-2|+6= 18$ is x=3,-1.

So, Option 2 is correct.

The answer is x=3, x= -1

What is the average (mean) of the following numbers: 2, 5, 8, and 1? Options: 4 3 5 4.5

Answers

Answer:

mean = 4

Step-by-step explanation:

the average ( or mean ) of a data set is calculated as

mean = $(sum)/(count)$

sum = 2 + 5 + 8 + 1 = 16

count = 4 ( number of values in data set )

substitute these values into the formula for mean

mean = $(16)/(4)$ = 4

Final answer:

The mean (average) of the numbers 2, 5, 8, and 1 is calculated by adding the numbers together (which gives 16), and then dividing this sum by the total number of numbers (4). So, the mean of these numbers is 4.

Explanation:

The subject of this question is Mathematics and it relates to the concept of statistical mean (average). To find the mean of the numbers 2, 5, 8, and 1, you add them all up and then divide by the number of numbers.
