6 = 1 - 8n + 5
an
Solve

Answers

Answer:

n=0

Step-by-step explanation:

simplifying

6 = 1 + -8n + 5

Reorder the terms:

6 = 1 + 5 + -8n

Combine like terms: 1 + 5 = 6

6 = 6 + -8n

Add '-6' to each side of the equation.

6 + -6 = 6 + -6 + -8n

Combine like terms: 6 + -6 = 0

0 = 6 + -6 + -8n

Combine like terms: 6 + -6 = 0

0 = 0 + -8n

0 = -8n

Solving

0 = -8n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '8n' to each side of the equation.

0 + 8n = -8n + 8n

Remove the zero:

8n = -8n + 8n

Combine like terms: -8n + 8n = 0

8n = 0

Divide each side by '8'.

n = 0

Simplifying

n = 0

N=0! Easy . Pls thanks !!

A fruit company delivers its fruit in two types of boxes: large and small. A delivery of 3 large boxes and 8 small boxes has a total weight of 91 kilograms. A delivery of 5 large boxes and 2 small boxes has a total weight of 78 kilograms. How much does each type of box weigh?

Answers

Answer:

the large box weight is 6.50 kg and the small box weight is 13 kg

Step-by-step explanation:

The calculation of each type of box weight is shown below:

Let assume the large box be x

And, the small box be y

Therefore

 3x + 8y = 91.......(i)

5x + 2y = 78.......(ii)

Multiply by 5 in equation 1 and by 3 in equation 2

15x + 40y = 455

15x + 6y = 234

Now deduct the last equation from the above one

34y = 221

y = 6.5 kg

For x, it is

3x + 8(6.5) = 91

3x + 52 = 91

3x = 91 - 52

3x  = 39

x = 13 kg

Hence, the large box weight is 6.50 kg and the small box weight is 13 kg

What is equation of a line?

The equation of a line is a form of representing the set of points, which form a line in a coordinate system. 

The general equation of a straight line is given as:

y = mx + c,

where m = slope of the line and c = y-intercept.

We have,

A line on a graph.

Three points are given on the graph:

(2, -8), (0, 2), and (7, 2)

We can select any two points and find the slope of the line.

The slope of a line is given as:

Slope = (d - b) / (c - a)

Where (a, b) and (c, d) are the two points.

(a, b) = (2, -8) and (c, d) = (0, 2)

Slope = (2 - (-8)) / (0 - 2)

Slope = (2 + 8) / -2

Slope = 10 / -2

Slope = -5

Thus,

The slope of the given line is -5.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total number of students in the class be A

Now , the value of A is

The number of students in the class who likes apples = 20 students

The percentage of students who likes apples = 40 %

So , the equation will be

percentage of students who likes apples x total number of students in the class = number of students in the class who likes apples

Substituting the values in the equation , we get

( 40 / 100 ) A = 20

On simplifying the equation , we get

Multiply by 100 on both sides of the equation , we get

40A = 2000

Divide by 40 on both sides of the equation , we get

A = 2000 / 40

A = 50 students

Therefore , the value of A is 50 students

Hence , the total number of students is 50 students

The number of people living on a remote island decreases by 9% every 10 years. In 1950 there were 18000 living on the island. Calculate how many less people will be living on the island in 2020.

Answers

Answer: 9,301 people

Step-by-step explanation:

First find the number of years that have passed:

= 2020 - 1950

= 70 years

Population decreases every 10 years so in 7 years it would have increased:

= 70/10

= 7 times

In 2020 therefore:

= 18,000 * (1 - 9%)⁷

= 9,301 people
