The answer is B. <span>{(1, 2), (2,4), (−1, 2), (0,3)} because it's the only answer where the variables for x aren't repeated. For example, x is 3 twice in A, x is 5 twice in C, and x is -4 twice in D. Please mark me Brainliest! :)</span>

Step-by-step explanation:

To get to the next number we have the mulitply the one before by 1/8

Because we are multiplying each time it's a geometric sequence

Because it's a geometric sequence we have a common ratio

I wrote before that to get to the next number we have to multiply it by 1/8 so that's the common ratio

Effectus [21]

Answer:

50,803,200 ways

Step-by-step explanation:

In this situation, since you should alternate girl-boy or boy-girl, the line-up can either start with a boy or a girl kicking which would yield one of the two following patterns:

BGBGBGBGBGBGBG or GBGBGBGBGBGBGB.

For each of those patterns, there are 7! ways to arrange all boys and 7! ways to arrange all girls. The number of ways that a line-up can be made for one round of kicking is:

$n=2*7!*7!\\n=2*(7*6*5*4*3*2)^2\\n=50,803,200\ ways$

There are 50,803,200 ways to set the line-up.

What is the solution to the equation 5x = 40?

Dima020 [189]

To find X, we can divide 5 into 40.
40 divided by 5 is 8.
Now we can do 5 x 8. That is 40.

X=40

OR we can do it another way.
40 divided by 5 is 8.
Cross out 5 divided by 5.

Now we have 8. Still.
X is 8
