In linear equation, n = 15 is the value of equation .
What in mathematics is a linear equation?
A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."What is the linear equation's formula?
A linear equation has the slope-intercept form y = mx + b. Variables in the equation are x and y. When x is 0, the integers m and b provide the line's slope (m) and the value of y. (b).

An angle measures 111.4° more than the measure of its supplementary angle. What is the measure of each angle?
The measure of the supplementary angles are 34.3 and 145.7 degrees.
What are supplementary angles?Supplementary angles are those angles that sum up to 180 degrees.
In other words, two angles are Supplementary when they add up to 180 degrees.
Therefore, the angles measures 111.4° more than the measure of it's supplementary angle.
Hence,
let
x = measure of the other angle
x + x + 111.4 = 180
2x + 111.4 = 180
subtract 111.4 from both sides
2x + 111.4 - 111.4 = 180 - 111.4
2x = 68.6
divide both sides by 2
x = 68.6 / 2
x = 34.3
Other angle = 34.3 + 111.4 = 145.7°
Therefore, the measure of the supplementary angles are 34.3 and 145.7 degrees.

5. Which is closer to Earth, Venus or
Mars? How much closer is it?
6. How much farther is the Earth from
Saturn than it is from Mars?
1) Earth is 403,400,000 miles farther from Saturn than it is from Jupiter.
2) The total distance from Saturn to Jupiter and from Jupiter to Mars is 745,400,000 miles.
3) Saturn is 390,000,000 miles closer to Jupiter than is is to Earth.
4) Total distance from Mercury to Earth is 56,700,000 miles.
5) Venus is 22,300,000 miles closer to Earth than Mars.
6) Earth is 745,000,000 miles farther from Mars than Saturn.
Given,
1) Distance from Earth to Saturn = 793,000,000 miles
Distance from Earth to Jupiter = 390,400,000 miles
793,000,000 - 390,400,000 = 403,400,000
That is, Earth is 403,400,000 miles farther from Saturn than it is from Jupiter.
2) Distance from Saturn to Jupiter = 403,400,000 miles
Distance from Jupiter to Mars = 342,000,000 miles
403,400,000 + 342,000,000 = 745,400,000
Therefore, the total distance from Saturn to Jupiter and from Jupiter to Mars is 745,400,000 miles.
3) Distance from Saturn to Jupiter = 403,400,000 miles
Distance from Saturn to Earth = 793,800,000 miles
793,800,000 - 403,400,000 = 390,400,000
So, Saturn is 390,000,000 miles closer to Jupiter than is is to Earth.
4) Distance from Mercury to Venus = 30,700,000 miles
Distance from Venus to Earth = 26,000,000 miles
30,700,000 + 26,000,000 = 56,700,000
That is, the total distance from Mercury to Earth is 56,700,000 miles.
5) Distance from Earth to Venus = 26,000,000 miles
Distance from Earth to Mars = 48,300,000 miles
48,300,000 - 26,000,000 = 22,300,000
That is, Venus is 22,300,000 miles closer to Earth than Mars.
6) Distance from Earth to Saturn = 793,800,000 miles
Distance from Earth to Mars = 48,300,000 miles
793,800,000 - 48,300,000 = 745,500,000
That is, Earth is 745,000,000 miles farther from Mars than Saturn.

Four students plan to rent a minivan for the weekend and equally share the rental cost. By adding one more people, they can each save $6. How much is the total rent of the car?
The amount of the total rent is 120 dollars.
How to find the total rent using average?Four students plan to rent a minivan for the weekend and equally share the rental cost.
By adding one more people, they can each save $6.
Therefore, the 4 students equally share the rent.
Hence,
average for 4 student = total amount shared / number of student
average for 4 student = x / 4
When you add one more person,
average for 5 student = x / 5
Therefore, the difference, will give you the total amount of the rent.
x / 4 - x / 5 = 6
5x - 4x/ 20 = 6
x / 20 = 6
cross multiply
x = 20 × 6
x = 120
Therefore, the amount of the total rent is 120 dollars.

C = 27Tr
Enter
The circumference of the circle with radius 7 and value of pie 3, using the formula C= 2pie r is 42 unit.
Circumference of this circle using 3 for TT and 7 as radius.
The circumference of a circle is the distance around the outside of the circle. It is like the perimeter of other shapes like squares. You can think of it as the line that defines the shape. For shapes made of straight edges this line is called the perimeter but for circles this defining line is called the circumference. There are two other important distances on a circle, the radius (r) and the diameter (d). The radius, the diameter, and the circumference are the three defining aspects of every circle. Given the radius or diameter and pi you can calculate the circumference.
Circumference of circle = π x Diameter of circle.
You can also work out the circumference of a circle if you know its radius. Remember that the diameter is double the length of the radius. We already know that C = πd. If r is the radius of the circle, then d = 2r. So, C = 2πr.
Here, π = 3, r = 7,
So C = 2*7*3 = 42 units.

The equivalent expression of the given expression is 5n/4 -3/8
What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
Here, the given expression is :
(-2 ¹/₂n + ¹/₄) + (3 ³/₄n - 5/8)
simplifying the above expression by taking like considering like terms :
= -2 ¹/₂n + 3 ³/₄n + ¹/₄- 5/8
= (15/4)n - (5/2)n + (2-5)/8
= (15-10)n/4 -3/8
= 5n/4 -3/8
Therefore, the equivalent expression of the given expression is 5n/4 -3/8.

Mediante la ley del seno, la longitud del faro es aproximadamente igual a 8.295 metros.
¿Cómo determinar la longitud del faro mediante leyes trigonométricas?
En esta pregunta nos encontramos con una sistema geométrico con dos ángulos y un lado conocidos, la configuración permite determinar la altura del faro mediante la ley del seno, cuya expresión sería la siguiente:
AC / sin B = AB / sin C = BC / sin A
Donde BC es la longitud del faro, medida en metros, y AC es la distancia horizontal hasta la base del faro, medida en metros. Si sabemos que AC = 9.9 m, B = 53° and A = 42°, entonces la longitud del faro es:
(9.9 m) / sin 53° = BC / sin 42°
BC = 9.9 m × (sin 42° / sin 53°)
BC ≈ 8.295 m

As per the question statement, Hector has shortlisted 11 documentaries and 15 foreign films, from which he wants to rent any 4 movies.
We are required to calculate the total of number of combinations of 4 movies from his above mentioned shortlist.
Total number of movies Hector has shortlisted = (11 + 15) = 26.
That is, we will have to calculate the total of number of combinations of 4 movies, Hector can rent from a lot of 26 movies.
