Answer:

x = 8

Step-by-step explanation:

[tex] - \frac{1}{2} x + 3 = - x + 7[/tex]

Collect like terms and simplify

[tex] - \frac{1}{2} x + x = 7 - 3 \\ \frac{1}{2} x = 4[/tex]

Cross Multiply

[tex]x \times 1 = 2 \times 4 \\ x = 8[/tex]

Answer:

x = 8

Step-by-step explanation:

-1/2x+3=-x+7

Add x to each side

-1/2x+x+3=-x+x+7

1/2x+3=7

Subtract 3 from each side

1/2x +3-3=7-3

1/2x=4

Multiply by 2

1/2x*2 = 4*2

x = 8

What makes a pair linear?

Answers

Answer:

A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

Answer: {-1, 0, 1}

Explanation: The range of a relation is the set of all y-coordinates.

So the range is {1, 0, -1} which would be your answer.

Note however that the range is usually written in ascending order.

In other words, from least to greatest.

So our range can be written as {-1, 0, 1}.

Write an equation and solve for x using the given information. (see image attached)

Answers

Answer:

Equation : 6x + 8 = 26

x = 3

Step-by-step explanation:

The given shape is a rectangle.

Here ( x + 1 ) cm and ( 2x + 3 ) cm are the sides,

where,

Length ( l ) = 2x + 3

Breadth ( b ) = x + 1

Perimeter is the sum of all sides.

Formula : -

Perimeter of a rectangle = 2 ( l + b )

Perimeter of a rectangle

= 2 ( 2x + 3 + x + 1 )

= 2 ( 2x + x + 3 + 1 )

= 2 ( 3x + 4 )

= 2 ( 3x ) + 2 ( 4 )

= 6x + 8

The given value of the perimeter is 26 cm.

So the equation is,

6x + 8 = 26

The value of x can be found by solving this equation.

6x + 8 = 26

Subtract 8 on both sides,

6x = 26 - 8

6x = 18

Divide 6 on both sides,

x = 18 / 6

x = 3

Hence the value of x is 3.

The Edwards family spends $800 per month on groceries for their family. If this is 18% of their monthly budget, then what is their monthly budget?

Round to the nearest cent (hundredths place).

Answers

Answer:

Monthly budget = $4444.44

Step-by-step explanation:

Let the monthly budget of Edwards family = x dollars

18% of monthly budget spends on groceries

Hence,

18% of x = 800

[tex]{\dfrac{ 18 }{ 100 } \times x = 800}[/tex]

[tex]\mathrm{Multiply\:both\:sides\:by\:100\:to\:cancel\:out\:the\:fraction}[/tex]

[tex]\mathrm{Divide\:18\:from\:both\:sides}[/tex]

[tex]\dfrac{ 18x }{ 18 } = \dfrac{ 80000 }{ 18 }[/tex]

You are in line at a ticket window. There are two more people ahead of you than there are behind you. The number of people in the entire line (don’t forget to count yourself!) is three times the number of people behind you. How many people are ahead of you in line, and how many are behind you?

Answers

Step-by-step explanation:

Let people behind you=x

People ahead of you will be x+2

Total number of people in the line(including you) = x+(x+2)+1 = 2x+3

Also, 2x+3=3x

So x=3

People ahead = x+2 = 5

People behind = x = 3

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

We have:

A ribbon is cut into 2 pieces so that piece x is half as long, in feet, as piece y.

x = y/2

or

2x = y

Based on the above equation the pairs of (12,24) (18,36), (24, 48), and (30, 60) satisfy the equation.

Thus, the ribbon cuts into the pieces are (12,24) (18,36), (24, 48), and (30, 60) which satisfy the equation.

The pages of Ayhan's book are numbered from 1. The page numbers have a total of 459 digits.

How many pages does the book have?
A) 119
D) 215
B) 189
E) 219
C) 190

Answers

Step-by-step explanation:

the first 9 pages have 1 digit (1 to 9).

the next 90 pages have 2 digits (10 to 99).

that is in total

9×1 + 90×2 = 189 digits.

that leaves us

459 - 189 = 270 digits for pages with 3 digit page numbers (100 and up).

there are 900 pages with 3 digit page numbers = 2700 digits, which is larger than 270.

so, the solution must be in this interval (there are no pages with 4 digit page numbers like 1000).

after how many pages with 3 digit pages numbers do we have a total of 270 digits ?

270/3 = 90 pages.

so, we have 9 + 90 + 90 = 189 pages in the book.
