Answer:

I'm going to say a arithmetic sequence

Step-by-step explanation:

I say this because a arithmetic sequence of numbers such that the difference between the consecutive terms is constant. Difference here means the second minus the first. For instance, the sequence 5, 7, 9, 11, 13, 15.. . is an arithmetic progression with common difference of 2. So, when Nya sent the letter to 4 friends, her friends copied and sent it to four other friends. So, the sequence would be (if it continues) 4, 8, 12, 16, 18, etc.

Elimination_4x_2y=14<br> _10x+7y=_24

Gnesinka [82]

Answer:

The answer is $x=-\frac{50}{8}$ and $y=\frac{11}{2}.$

Step-by-step explanation:

Given:

-4x-2y=14

-10x+7y=-24

Now, to solve it by elimination:

$-4x-2y=14$ ......(1)

$-10x+7y=-24$ ......(2)

So, we multiply the equation (1) by 7 we get:

$-28x-14y=98$

And, we multiply the equation (2) by 2 we get:

$-20x+14y=-48$

Now, adding both the new equations:

$-28x-14y+(-20x+14y)=98+(-48)$

$-28x-14y-20x+14y=98-48$

$-28x-20x-14y+14y=50$

$-8x=50$

<em>Dividing both the sides by -8 we get:</em>

$x=-\frac{50}{8}$

Now, putting the value of $x$ in equation (1):

$-4x-2y=14$

$-4(-\frac{50}{8})-2y=14$

$\frac{200}{8} -2y=14$

$25-2y=14$

<em>Subtracting both sides by 25 we get:</em>

$-2y=-11$

<em>Dividing both sides by -2 we get:</em>

$y=\frac{11}{2}$

Therefore, the answer is $x=-\frac{50}{8}$ and $y=\frac{11}{2}.$

AABC - ADEF <br><br> Find the value of x

kobusy [5.1K]

Answer:

$\boxed{x = 4}$

Step-by-step explanation:

If ΔABC ~ ΔDEF

Then their sides must be proportional such that:

=> $\frac{x}{3} = \frac{8}{6}$

Cross Multiplying

=> x * 6 = 8*3

=> 6x = 24

Dividing both sides by 6

=> x = 4
