-2 + n = -8(1 - 8n) + 6
Distribute the -8
-2 + n = -8 + 64n + 6
Combine like terms.
-2 + n = 64n - 2
Add 2 to both sides and subtract n from both sides.
0 = 63n
Divide both sides by 63
0 = n

Answer:
23 percent
Step-by-step explanation:
The percentage of females who are freshmen or sophomores will be 50%.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol 'percent' is used to symbolize it.
The frequency table shows the distribution of 1,200 students at a high school.
The frequency table is given below.
Then the percentage of females who are freshmen or sophomores will be
P = (134 + 162) / 592 x 100
P = 296 / 592 x 100
P = 0.5 x 100
P = 50%
Thus, the correct option is B.

Point K is on line segment JL. Given JK = 5x + 7, JL = 2x + 8, and
KL= 4, determine the numerical length of JL.
Answer:
The answer to your question is 8.666666666666.
The total numerical length of the segment JL is 6 units.
Given that,
Point K is online segment JL.
JK = 5x + 7,
JL = 2x + 8, and KL= 4
To determine the numerical length of JL.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
For point K on the line segment JL,
JL = JK + KL
from given,
2x + 8 = 5x + 7 + 4
5x -2x = 8 - 11
3x = -3
x = -1
Now,
JL = 2x + 8
JL = 2 * -1 + 8
JL = 6
Thus, the total numerical length of the segment JL is 6 units.

The intersection of the plane X and plane Y is line CQ.
What is plane?A plane is a two-dimensional flat surface in geometry. It has no thickness and goes on forever.
Here, we have two planes, X and Y.
There will always be a line at the intersection of two planes.
The planes should intersect in a straight line as long as they are not parallel.
Let CQ be the extended line of CB.
And here we have line CQ.

Could someone uh, help me? I’m a bit confused.
the coordinate of point T are (6,12). The midpoint of ST is (3,-8). Find he coordinates of point S. the other endpoint is?
Answer:
(0, -28)
Step-by-step explanation:
Midpoint coordinates are equal to average of the value of endpoint coordinates.
One of End points is T (6,12), the other one is S (x, y) and the midpoint is (2, -8)
So midpoint formula applied to both coordinates:
3 = (6+x)/2 ⇒ 6 = 6+ x ⇒ x = 6 - 6 ⇒ x = 0-8 = (12 + y)/2 ⇒ -16 = 12 + y ⇒ y = -16 - 12 ⇒ y = - 28Point S has coordinates of (0, -28)

Vertical Angles
Step-by-step explanation:
Vertical Angles are the angles opposite each other when two lines cross.
It is found that angle 2 and angle 1 are vertically opposite angles.
What is vertically opposite angles?The vertically opposite angles are those angles that are opposite one another at a specific vertex and are created by two straight intersecting lines.
Thus, Each of the pairs of the opposite angles made by two intersecting lines are called vertical angles.
Also, When you slice a given object vertically (perpendicular to the ground level), then the sliced surface is called vertical cross section.

A gamestop you can buy a xbox one foe 150.00 and each game to go with it would cost 24.00 or you can buy a playstation 4 for 180.00 abd esch game for 20.00
Answer:
Let's write two linear equations:
For the Xbox, we have:
Price per console (you pay it only once) = $150.
Price per game = $24
Then, the total price if you buy x games, you have:
P1(x) = $150 + $24*x
For the Playstation we have:
Price per console (again yo pay it only once) = $180
Price per game = $20
So if you buy x games, the total price is:
P2(x) = $180 + $20*x.
Now, we can find the number x such that both prices are equal
P1(x) = P2(x)
$150 + $24*x = $180 + $20*x.
let's solve this for x.
$24*x - $20*x = $180 - $150
$4*x = $30
x = $30/$4 = 7.5
What does this mean?
If you buy less than 7.5 games (7 or less) then the Xbox will be cheaper, because the y-intercept is smaller.
If you buy more than 7.5 games (8 or more) then the Playstation will be cheaper, because the price per game is smaller.
If you multiply -13 by itself 35 times will the answer be negative?

solve for v bellow. 8(z-5)=16
Answer:
z=7
Step-by-step explanation:
8(z-5)=16
Divide by 8
8/8(z-5)=16/8
z-5 = 2
Add 5 to each side
z-5+5 = 2+5
z = 7
Answer:
z = 7
Step-by-step explanation:
Expand 8 ( z - 5 ) = 16 first.
8z - 40 = 16
Move 40 to the other side.
8z = 40 + 16
8z = 56
z = 7
