Please Tell Me The Step Process Of This Btw This Is 7th-grade Math Its Angle Measurements I'm Confused

Answers

Answer 1

Answer:

Angle BDA is 90°

(2x + 3) + 55 = 90

2x + 3 + 55 = 90

2x + 58 = 90

2x = 90 - 58

2x = 32

x = 32/2

x = 16

Hence,

x=16

x=16Angle BDA is 90°.

Solve the equation for x

Answers

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:

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

5=%10

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

(4x-5)

(4x-3)

(3x+6)

Answers

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 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.
