Answer:
y=17
Step-by-step explanation:
19=2y-15
move the variable to the left-hand side and change its sign
-2y+19=-15
move the constant to the right-hand side and change its sign
-2y=-15-19
Calculate the difference
-2y=-34
divide both sides by -2
y=17

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.
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

Solve the equation for x
Answer:
x = 0
Step-by-step explanation:
Given the diagram, we know that the left side is the same as -2x + 6 and the right side as -6. We can write an equation and solve for x.
-2x + 6 = 6
~Subtract 6 to both sides
-2x = 0
~Divide -2 to both sides
x = 0
Best of Luck!
Answer:
x=0
Step-by-step explanation:
-2x+6=-6
-2x=0
x=0

6 = 1 - 8n + 5
an
Solve
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
What is the slope of this line?
Enter your answer as a whole number or a fraction in simplest form in the box.
Answer:
0
Step-by-step explanation:
the slope of this line is a zero slope as it is completely horizontal
The slope is the steepness of a line.
The slope of the given line is -5.
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.

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?
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

Find the value of x in the figure.
(4x-5)
177
(4x-3)
(3x-3)
118
(3x+6)
Answer:
x = 35
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 6, then
sum = 180° × 4 = 720°
sum the given angles and equate to 720
4x - 5 + 117 + 3x - 3 + 3x + 6 + 118 + 4x - 3 = 720, that is
14x + 230 = 720 ( subtract 230 from both sides )
14x = 490 ( divide both sides by 14 )
x = 35

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
