Answers

Answer:

Addition Property of Equality

Step-by-step explanation:

So we had:

[tex]3x-2=7[/tex]

And then we got:

[tex]3x=9[/tex]

We did this by adding 2 to both sides of the equation. When we added 2, the left side cancelled and the right side equated to 9:

[tex](3x-2)+2=(7)+2\\3x=9[/tex]

Since we added 2 to both sides, this is an example of the addition property of equality.

The area of the new rectangle in terms of x is  2x² - 3x + 1 sq inches.

What are the area and perimeter of a rectangle?

The area of a rectangle is the product of its length and width.

The perimeter of a rectangle is the sum of the lengths of all the sides.

We know the area of a rectangle is (length×width).

Given,  A paper with a width of x inches, and a length of 2x inches.

So, The area is (x×2x) sq inches.

= 2x² sq inches.

Now, he cut off one inch of both the length and the width which is,

= (x - 1)(2x - 1) sq inches.

= 2x² - x - 2x + 1 sq inches.

= 2x² - 3x + 1 sq inches.

A local library claims it has 2.73x103 books. If there are 42 people in the building, how many books per capita are there?

Answers

Answer:

[tex]Per\ Capita = 64[/tex]

Step-by-step explanation:

Given

[tex]Books = 2.7 * 10^3[/tex]

[tex]People = 42[/tex]

Required

Determine the per capita

The per capita is calculated by dividing number of books by people as follows;

[tex]Per\ Capita = \frac{Books}{People}[/tex]

Substitute 2.7 * 10^3 for books and 42 for people

[tex]Per\ Capita = \frac{2.7 * 10^3}{42}[/tex]

[tex]Per\ Capita = 64[/tex] (Approximated)

Hence, the per capita is 64

12. Higher order Thinking is the Product of two irrational numbers always an irrational number ? Explain​

Answers

Answer:

Not always but sometimes

Step-by-step explanation:

The product of two irrational numbers is sometimes and not always an irrational number.

So, Let us take two Example:

Example # 1:

Let the two irrational numbers be [tex]\sf \sqrt{37} \ and \ \sqrt{2}[/tex]

So, Multiplying these will give us

=> [tex]\sf \sqrt{37} * \sqrt{2}[/tex]

=> [tex]\sf \sqrt{74}[/tex]

Which is an irrational number.

Example # 2:

Let the two irrational numbers be [tex]\sf \sqrt{2} \ and \ \sqrt{2}[/tex]

So, Multiplying them would give us:

=> [tex]\sf \sqrt{2} * \sqrt{2}[/tex]

=> [tex]\sf (\sqrt{2} )^2[/tex]

=> 2

Which is a rational number.

This means that the product of two irrational numbers is not always an irrational number but sometimes an irrational number.

Answers

Answer:

a) (1, 2) not on the graph.

b) (1, -1) is on the graph.

Step-by-step explanation:

Given the equation of the line as:

[tex]2x - y - 3 = 0[/tex]

The points given are

a) (1, 2)

To determine whether it is on the graph of the line or not.

To do so, we can do 2 things:

1. Draw the graph and plot the point on the graph to check whether it is on the graph or not.

2. To put the point in the given equation of the line, whether the equation is satisfied or not.

For method 1: Kindly refer to the attached image of the line and point plotted.

Method 2:

Let us put [tex]x=1, y=2[/tex] in the Left Hand Side (LHS) of equation.

[tex]2\times 1 - 2 - 3\\\Rightarrow -3 \neq 0 , RHS[/tex]

(1, 2) Not on the graph.

(b) (1, -1)

For method 1: Kindly refer to the attached image of the line and point plotted.

Method 2:

Let us put [tex]x=1, y=-1[/tex] in the Left Hand Side (LHS) of equation.

Best regards! :D

Answer:

[tex]x=4[/tex]

Step-by-step explanation:

[tex]2x+4=12[/tex]

To solve this equation, first we must minus out(subtract) 4 from both sides of the equation.

[tex]2x+4-4=12-4[/tex]

This equals [tex]2x=8[/tex]

Now we will make this into a fraction and divide the sides by 2.

Answers

Answer:

Property of Equality

Y= -13/7

Step-by-step explanation:

7y – 15 = –29.

Applying rule of equality which is"anything done on one side of the equal sign should be done also on the other side of the equal sign"

7y – 15 = –29.

Adding 15 to both sides

7y - 15+15= -28+15

7y= -13

Dividing throughout by 7

7y/7= -13/7

Find the missing number to make the average correct. The average of 11, 17, 18, and ? is 17.

4 numbers and your average is 17

then:

17*4 = 68

then:

11 + 17 + 18 + a = 68

46 + a = 68

a = 68 - 46

a = 22

Mark is three times as old as Julie. The sum of their ages is 56. How old is Mark? If J = Julie's age and M = Mark's age, which system of equations could be used to solve the problem? 3J = M and J + M = 56 J = 3M and J + M = 56 J = 3M and JM = 56

Answers

Answer:

Mark is 42. 3J = M and J + M = 56

Step-by-step explanation:

Since Mark is 3 times as old as Julie, and the sum of their ages is 56, you could divide 56 by 4 (one time because of Julie’s age, the other 3 times because of how many times Mark is older than Julie) You would get 14. That means that Julie is 14. To find Mark’s age, you would multiply 14 (Julie’s age) by 3. The answer would be 42.
