Step-by-step explanation:
n/4 + n/4 + n/4 + n/4 = 4n/4 = n
On solving the expression, n/4 + n/4 + n/4 + n/4 , we get n.
What is a expression? What is a mathematical equation? What is equation modelling?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have the following expression -
n/4 + n/4 + n/4 + n/4
We can write -
n/4 + n/4 + n/4 + n/4
n/4(1 + 1 + 1 + 1)
4 x n/4
n
Therefore, on solving the expression, n/4 + n/4 + n/4 + n/4 , we get n.

An exterior angle of a triangle is formed by any side of a triangle and the extension of its adjacent side. An exterior angle of a triangle is equal to the sum of the two opposite interior angles. Find the values of x and y in the following triangle. y + 92° = 180° (interior angle + adjacent exterior angle = 180°.)

14. Which is the equation of the line that passes through the points (4, 3) and (6, 2)?
A. y = x –1
B. y = 0.5x –1
C. y = -0.5x + 5
D. y = -0.5x + 1
The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
The equation of the line is y = -0.5x + 5
Option C is the correct option.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
The equation of the line y = mx + c.
The line passes through (4, 3) and (6, 2).
This means,
We can find the slope using the coordinates (4, 3) and (6, 2).
Slope = m
m = (2 - 3) / (6 - 4)
m = -1 / 2
Now,
For the y-intercept.
Take any point.
(4, 3) = (x, y)
y = mx + c
3 = (-1/2)4 + c
3 = -2 + c
3 + 2 = c
c = 5
Now,
m = (-1/2) = -0.5
c = 5
The equation of the line is y = -0.5x + 5
Thus,
The equation of the line is y = -0.5x + 5
Option C is the correct option.

Find the sum of the arithmetic series given a1
12, d = 4, and n = 30.
A. 8434
B. 4200
C.4216
D. 2100
Answer:
D
Step-by-step explanation:
The sum to n terms of an arithmetic series is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = 12, d = 4 and n = 30 , then
[tex]S_{30}[/tex] = [tex]\frac{30}{2}[/tex] [ (2 × 12) + (29 × 4) ]
= 15(24 + 116)
= 15 × 140
= 2100 → D
The sum of the arithmetic series given a₁ =12, d = 4, and n = 30 is 2100, therefore the correct answer is D.
What is the Sum of arithmetic series?The sum of n terms of an arithmetic series can be easily found using a simple formula which says that, if we have an arithmetic series whose first term is a and the common difference is d, then the formula of the sum of n terms of the arithmetic series is as follows
Sn = n/2 [2a₁ + (n-1)d].
as given in the problem
a₁ =12, d = 4, and n = 30
Sn = 30/2 [2×12 + (30-1)×4]
= 2100
The sum of the arithmetic series given a₁ =12, d = 4, and n = 30 is 2100.
