N = 1 or 2n = 2

8n -3n + 12 = 3n + 14
5n + 12 = 3n + 14
2n = 2
N = 2

Solving 8n-3(n-4)
=8n-3n+12 (multiply -3 to n and -4)
=5n+12
we got 14+3n=5n+12

now subtract 5n to both sides
3n-5n=-2n and on the right side cross out 5n from the right side because 5n-5n=0

we got 14+-2n=-12

subtract 14 to both sides ( cross out 14 from the left side and subtract it to -12

we got -2n=-26

divide -2 to both sides

so the answer =13

Helpp me asapp with this problem plss will crown brainiest !!!!

Answer:

see below

Step-by-step explanation:

Since RT bisects QRS

1/2 QRS = TRS

1/2 ( 9x+214) = -9x+53

Multiply each side by 2

9x +214 = -18x+ 106

Add 18x from each side

9x +214+18x = 106

27x +214 = 106

Subtract 214 from each side

27x = 106-214

27x =-108

Divide by 27

27x/27 = -108/27

x = -4

TRS = -9x+53

=-9 *-4 +53

= 36+ 53

=89

Missing part of the question

Determine the number of handshakes, i, that will occur for each number of people, n, in a particular room. (people)

Answer:

$S_n = \frac{n}{2}(n - 1)$

Step-by-step explanation:

Given

For 5 people

$\begin{array}{cc}{People} & {Handshakes} & {5} & {4} & {4} & {3} & {3} & {2} & {2} & {1} & {1} & {0} &{Total} & {10} \ \end{array}$

Using the given instance of 5 people, the number of handshakes can be represented as:

$(n - 1) + (n - 2) + (n - 3) + ........ + 3 + 2 + 1 + 0$

The above sequence is an arithmetic sequence and the total number of handshakes is the sum of n terms of the sequence.

$S_n = \frac{n}{2}{(T_1 + T_n})$

Where

$T_1 = n - 1$ --- The first term

$T_n = 0$ --- The last term

So:

$S_n = \frac{n}{2}(n - 1 + 0)$

$S_n = \frac{n}{2}(n - 1)$
