The problem statements needs to be properly formatted

3.5, -2.1, √ 9, -7/2, and√5.

let us find all square roots given in the list

√ 9= 3

√5= 2.23

hence we have 3.5, -2.1, 3, -7/2, and 2.23.

Also let us convert all fractions to decimal numbers

-7/2= -3.5

3.5, -2.1, 3, -3.5 and 2.23.

from least to greatest we have

-3.5,-2.1,2,2.23,3,3.5

or

3.5, -2.1, √ 9, -7/2, and√5.

-7/2,-2.1,√5, √9, 3.5

Steps to solve:

x - 12 = 40

~Ad 12 to both sides

x = 52

Best of Luck!

Step-by-step explanation:

3x - 2x = 2

x = 2

2. 3x + 5 = 4x + 1

4x - 3x = 5 - 1

x = 4

3. 6x + 3 = 3x + 12

6x - 3x = 12 - 3

3x = 9

x = 3

The difference between tax credit and a tax deduction is that- a tax credit reduces the amount of money you must pay, while a tax deduction reduces your taxable income.

A financial charge that is imposed on a taxpayer in order to fund government spending and public expenditures is called tax. It is imposed by a governmental organization. It is a compulsory charge.

Given is tax credit and a tax deduction.

Tax credits and a tax deductions are same in a way that they will decrease what you pay in taxes. However, the method in which each of them work is quite different. Tax deductions lower your taxable income and will reduce what you'll pay in taxes, while tax credits reduce your tax bill dollar for dollar and may even increase your refund.

Therefore, the difference between tax credit and a tax deduction is that- a tax credit reduces the amount of money you must pay, while a tax deduction reduces your taxable income.

Answer:

The square root of any prime number must be an irrational number. For example, because of this proof we can quickly determine that √3, √5, √7, or √11 are irrational numbers...

Answer:

Yes, unless X is a perfect square, sqrt(X) is irrational

Step-by-step explanation:

The proof where X= 2 is an example of the general proof: Supposesqrt(X) is rational, then there exists integers p and q such that (p/q)^2 = 2, we can cancel any common factors out of p and q so these are the simplest integers which satisfy the equation.

Answer:

The percentage of country A population to the world population

= 3.05%

Step-by-step explanation:

Country A population as of 2016

= 226 million

= 226000000

The world population as of 2016

= 7.4 billion

= 7400000000

The percentage of country A population to the world population

= Country A population /The world population

The percentage of country A population to the world population

= 226000000/7400000000

The percentage of country A population to the world population

= 0.03054

Now multiplying by 100

= 3.05%

The percentage of country A population to the world population is  3.05%

Given that,

Based on the above information, the calculation is as follows:

[tex]= 226000000\div 7400000000[/tex]

= 0.03054

= 3.05%

Answer:

d. x = 5

Step-by-step explanation:

Solve for x:

x - 3 = 7 - x

Hint: | Move terms with x to the left hand side.

Add x to both sides:

x + x - 3 = (x - x) + 7

Hint: | Look for the difference of two identical terms.

x - x = 0:

x + x - 3 = 7

Hint: | Add like terms in x + x - 3.

x + x = 2 x:

2 x - 3 = 7

Hint: | Isolate terms with x to the left hand side.

Add 3 to both sides:

2 x + (3 - 3) = 3 + 7

Hint: | Look for the difference of two identical terms.

3 - 3 = 0:

2 x = 7 + 3

Hint: | Evaluate 7 + 3.

7 + 3 = 10:

2 x = 10

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 2 x = 10 by 2:

(2 x)/2 = 10/2

Hint: | Any nonzero number divided by itself is one.

2/2 = 1:

x = 10/2

Hint: | Reduce 10/2 to lowest terms. Start by finding the GCD of 10 and 2.

The gcd of 10 and 2 is 2, so 10/2 = (2×5)/(2×1) = 2/2×5 = 5:

Answer:

[tex]f(-3)=24[/tex]

Step-by-step explanation:

So we have the function:

[tex]f(x)=|4x-2|+10[/tex]

To find f(-3), substitute -3 for x:

[tex]f(-3)=|4(-3)-2|+10[/tex]

Multiply within the absolute value:

[tex]f(-3)=|-12-2|+10[/tex]

Subtract:

[tex]f(-3)=|-14|+10[/tex]

The absolute value of -14 is 14. Thus:

[tex]f(-3)=14+10[/tex]

Answer:

A and D

Step-by-step explanation:

Given that the area of a square = 400 units² = s²

Where s is one side length of the square.

It means that the side length (s) = √400 = 20

If the length of each side length increase by 1 units, new side length = 21 units

Area of new square = 21² = 441

The following statements would be true if the side length was increased by 1 units:

A. "The area of the square would be a rational number"

441 is a rational number, because a rational number is a quotient of two integers.

441 and 1 are two integers. Their quotient = 441. I.e. 441 ÷ 1 = 441

D. "The area of the square would be a perfect square".

A number is considered a perfect square if it can be expressed as a product of two equal integers.

441 can be expressed as 21*21

The value after simplifying the expression 3² + 8 ÷ 2 - (4 + 3) is 6 by using PEMDAS rule.

To simplify the expression 3² + 8 ÷ 2 - (4 + 3), follow the order of operations (PEMDAS/BODMAS):

P - Parentheses first

E - Exponents (i.e., powers and square roots, etc.)

MD - Multiplication and Division (left to right)

AS - Addition and Subtraction (left to right)

Start with the exponent:

3² = 3 × 3 = 9.

Next, perform the division:

8 ÷ 2 = 4.

Now, deal with the parentheses:

(4 + 3) = 7.

Finally, perform the addition and subtraction from left to right:

9 + 4 - 7

= 6.

So, the simplified expression is 6.

Answer: 15/32

Step-by-step explanation:

The data that we have is:

5/8 of the vegetable sold where green.

of theses 5/8, 3/4 were string beans.

Then the 3/4 is applied to the 5/8 of green vegetables.

Then the fraction (of the total number of vegetables) that were string beans was:

F  = (3/4)*(5/8) = (3*5)/(4*8) = 15/32

Distance = speed x time

Let the time to the appointment = x

The time home would be x + 1/4 hour

set up an equation you have 90x = 80(x + 1/4)

Simplify:

90x = 80x + 20

Subtract 80x from both sides:

10x = 20

Divide both sides by 10:

x = 2 hours

Distance = 90 x 2 = 180 miles

Steps to solve:

-6w - 8 + 15w = 2w - 8 + 7w

~Combine like terms

9w - 8 = 9w - 8

~Add 8 to both sides

9w = 9w

~Divide 9 to both sides

0 = 0

All real numbers are solutions.
