Step-by-step explanation:

Answer: x° is 50°

Step-by-step explanation: The sum of the exterior angles of a polygon is 360.

Add the given exterior angles:

35+50+20+125=230

to find the missing exterior angle, supplementary to x°,

Subtract 360 - 230 = 130

The Sum of Supplementary angles is 180°

x° + 130° = 180°

x = 50

Answer:

n = 14

Step-by-step explanation:

(n + 6)4 = 5

1. multiply by 4

n + 6 = 20

2. substract 6

n = 14

The required value of n is 14 in the given sum.

Algebra is the analysis of mathematical representations, while logic is the manipulation of those symbols.

We have been given that the sum of a number, n, and 6 is divided by 4 the result is equal to 5.

According to the given question, we can write the algebraic form would be as:

⇒ (n + 6)/4 = 5

Apply the cross-multiplication operation,

⇒ (n + 6) = 5 × 4

Apply the multiplication operation,

⇒ (n + 6) = 20

⇒ n = 20 - 6

Apply the subtraction operation,

⇒ n = 14

Therefore, the required value of n is 14.

Answer:

y = - 3x + 5

Step-by-step explanation:

Given

6x + 2y = 10 ( subtract 6x from both sides )

2y = - 6x + 10 ( divide all terms by 2 )

y = - 3x + 5

The correct equation for y in terms of x would be, y = - 3x + 5

Hence, option 2 is true.

Used the concept of an equation that states that,

An equation is a group of numerical variables and functions that have been combined using operations like addition, subtraction, multiplication, and division.

Given that the expression is,

6x + 2y = 10

Now, simplify the equation for y in terms of x as,

6x + 2y = 10

Subtract both sides by 6x,

2y = - 6x + 10

Divide both sides by 2,

y = - 3x + 5

So, The correct equation would be, y = - 3x + 5

Thus, option 2 is true.

Answer:

93.75 hours

Step-by-step explanation:

The Demir family has a monthly budget of $5,500. Mrs. Demir works fulltime and takes home $4,000 each month.

Hence, the amount of money Mr Demir is meant to bring at the end of the month is :

Monthly budget - Amount of money that Mrs Demir takes home

= $5,500 - $4,000

= $1,500

From the question, we are told that:

Mr. Demir works part-time and brings home earns $16 per hour. How many hours per month must Mr. Demir work at his part-time job to make sure that he and Mrs. Demir have met their monthly budget?

This is calculated as:

$16 = 1 hour

$1,500 = x

Cross Multiply

16 × x = 1500 × 1

x = 1500 /16

x = 93.75 hours

Therefore, Mr Demir must work for 93.75 hours in a month at his part time job.

Answer: {y,x} = {4,2} ) ) ) )4

Step-by-step explanation: y

[2] y = -2x + 8

// Plug this in for variable y in equation [1]

[1] (-2x+8) - x = 2

[1] - 3x = -6

// Solve equation [1] for the variable x

[1] 3x = 6

[1] x = 2

// By now we know this much :

y = -2x+8

x = 2

// Use the x value to solve for y

y = -2(2)+8 = 4

Solution :

{y,x} = {4,2}

Multiply total meters by 100 to get total centimeters:

6 meters x 100 = 600 centimeters.

Now divide total centimeters by 2.554 to get total inches:

600 centimeters / 2.54 = 236.22 inches.

Rounded to the nearest inch = 236 inches.

The grams of zinc the jar of chemical contain is 128 grams

In a certain​ chemical, the ratio of zinc to copper is 4 to 15 .

Therefore, a jar of the chemical contains 480 grams of copper.

The grams of zinc in the jar as follows:

Hence,

ratio of zinc to copper = 4 : 15

Therefore,

let

x = total grams in jar

Hence,

480 = 15 / 19 x

15x = 480 × 19

15x = 9120

x = 9120 / 15

x = 608

Therefore,

amount of zinc = 4 / 19 × 608

amount of zinc = 2432 / 19

amount of zinc = 128 grams

If the function is reflected across the yaxis of the graph of f, the resulting function will be g(x) = 5x + 4

Translation is the technique that is used to change the position of a figure on an xy-plane.

For instance, if the function f(x) is reflected in the y-axis, the resulting function will be g(x) = -f(x)

Given the function f(x)=|x|-3, if the function is reflected in the y-axis of the graph of f.f, the resulting function will be;

g(x) = f(-x)

g(x) = (-5x) + 4)

g(x) = 5x + 4

Answer: It will take 36 minutes(0.6 hour) until both ferries depart from their docks at the same time again.

Step-by-step explanation:

Given : Ferry A departs every 1.2 hours.

Ferry B departs every 1.8 hours.

To find : Time taken by both ferries until they depart from their docks at the same time again.

= LCM (1.2, 1.8) hours   [LCM= Least common multiple]

= LCM (1.2(60 minutes), 1.8(60 minutes))    [Since 1 hour = 60 minutes]

= LCM (72 minutes, 108 minutes)

72 = 2 x 2 x 2 x 3 x 3  , 108 = 3 x 3 x 3 x 2 x 2

LCM (72,108) =2 x 2 x 3 x 3 =36

So, it will take 36 minutes until both ferries depart from their docks at the same time again.

In hour = [tex]\dfrac{36}{60}\text{ hour}=0.6\text{ hour}[/tex]
