Answer:

9 and 15

Step-by-step explanation:

9 + 15 = 24/ 2 = 12

15 - 9 = 6

The two numbers are 15 and 9.

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. LHS = RHS is a common mathematical formula.

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.

We have,

Mean of two number is 12 and range is 6.

let the two number be a and b

So, Mean = (a + b)/ 2

12 = (a + b)/ 2

a+ b= 24.........(1)

Now, range = 6

a - b = 6........(2)

Solving equation 1 and 2 we get

2a = 24-6

2a = 18

a= 9

and, b= 24 - 9

b = 15

Combine like terms then factor them out

Answer:

Yes

Step-by-step explanation:

Multiplying an integer by 0.01 is the same as Dividing such as :

0.01 = 10^-2

100= 10

For instance :

A number, n = 5 is multiplied by 10^-2

5 * 0.01 = 0.05

Thus, divide the number, n by 100;

5 / 100 = 0.05

Hence, the proof.

The equation as a single logarithm is:

[tex]log[(x^2 - 16)/(x + 4)].[/tex]

Option C is the correct answer.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

Using the logarithmic identity,

log a - log b = log (a/b)

We can simplify the given expression as:

[tex]=log(x^2 - 16) - log(x + 4) \\= log[(x^2 - 16)/(x + 4)][/tex]

Therefore,

The equation as a single logarithm is:

[tex]log[(x^2 - 16)/(x + 4)].[/tex]

Answer: 37.1

Step-by-step explanation: 530 x .07

Answer:

$37.10

Step-by-step explanation:

You have to take the total price and multiply it by the decimal equivalent of the sales tax. In this case, 7% = 0.07, and so 530 x 0.07 = 37.10. If you wanted to get the total price (for future reference) then you would simply add the tax total to the original price.

Answer:

a = 3.8

Step-by-step explanation:

a : 5.7 = 8 : 12

It can be also written as -

[tex] \frac{a}{5.7} = \frac{8}{12} [/tex]

[tex] = > \frac{a}{5.7} = \frac{2}{3} [/tex]

Multiplying 5.7 on both the sides ,

[tex] = > \frac{a}{5.7} \times 5.7 = \frac{2}{3} \times 5.7 [/tex]

[tex] = > a = \frac{2}{3} \times 5.7 = 3.8[/tex]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the expression

5+5(9b - 7)

FIRST CASE (JUST EVALUATION)

Given the expression

[tex]5+5\left(9b-7\right)[/tex]

[tex]\mathrm{Apply\:the\:distributive\:law}:\quad \:a\left(b-c\right)=ab-ac[/tex]

[tex]5+5\left(9b-7\right)=5+5\cdot \:9b-5\cdot \:7[/tex]

                     [tex]=5+45b-35[/tex]

                     [tex]= 45b - 30[/tex]

Therefore, we conclude that:

[tex]5+5\left(9b-7\right)=45b-30[/tex]

SECOND CASE (Finding the value of b)

Assuming we have to determine the value of b

[tex]5+5(9b - 7) = 0[/tex]

As we have determined

[tex]5+5\left(9b-7\right)=45b-30[/tex]

so substituting [tex]5+5\left(9b-7\right)=45b-30[/tex] in the equation

[tex]45b-30 = 0[/tex]

Add 30 to both sides

[tex]45b-30+30=0+30[/tex]

Simplify

[tex]45b=30[/tex]

Divide both sides by 45

[tex]\frac{45b}{45}=\frac{30}{45}[/tex]

Simplify

[tex]b=\frac{2}{3}[/tex]

Therefore, the value of b = 2/3
