To convert from radical form to exponential in fractional form, we can follow:

Firstly, notice that 9 is the same as 3 squared:

Now, we can apply the change:

Also, notice that we can factor out the 2 on the denominator to cancel with the two on the numerator:

So, the expression in the simples form and fractional exponent is:

The result of the equation -3/2 = (-2/3)w - 4/5 is w = 21/20

The equation is

(-2/3)w - 4/5 = -3/2

Here we have to rearrange the terms and combine the like terms.

Mover 4/5 to the right hand side of the equation

(-2/3)w = -3/2 + 4/5

(-2/3)w = -7/10

Move the number (-2/3) to the right hand side of the equation

x = -7/10 ÷ (-2/3)

To make it multiplication, take the reciprocal of the the second number

x = -7/10 × (-3/2)

Multiply the numbers

x = 21/20

Hence, the result of the equation -3/2 = (-2/3)w - 4/5 is w = 21/20

So, It is a rational number.

3. 2√7

Since,  √7 is an irrational number.

So, 2√7 is not a rational number.

4. 100

It can be written as;

100 / 1

So, It is a rational number.

5. √0.36 = 0.6

              = 6 / 10

              = 3 / 5

Thus, It is a rational number.

6. √0.0144 = 0.12

                 = 12 / 100

                 = 3 / 25

The system of equations that could be used to determine the number of drinks and the number of tacos that Jordan bought are 2.5x + 2y = 26 and y = x + 4.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

Let's assume that number of drinks that Jordan and his children bought is x while the number of tacos is y.

The cost of drinks = 2.50x

Cost of tacos = 2y

Total cost 2.5x + 2y

2.5x + 2y = 26

Given that,

He bought 4 more tacos than drinks.

Therefore,

y = x + 4.

Hence "The system of equations that could be used to determine the number of drinks and the number of tacos that Jordan bought are 2.5x + 2y = 26 and y = x + 4".

In linear equation,  that price of shorts before discount was $25

What in mathematics is a linear equation?

Assume that the price of shorts after the discount is x

Total payment = price of shorts + taxes

We know that:

total payment = $21

taxes = 5% = 0.05 of the price

This means that:

21 = x + 0.05x

21 = 1.05x

x = $20

Therefore, the price of the shorts is $20 after the discount

Now, we will get the price of the shorts before the discount:

Assume that the price of shorts before discount is y

We know that:

The discount was 20%

This means that Jennifer paid:

100% - 20% = 80% of the price of the shorts

Therefore:

80% of the price = $20

0.8y = 20

y = $25

This means that price of shorts before discount was $25.

The amount of coffee she bought is 5.16 pounds.

She received a $70 gift card for a coffee store.

She used it in buying some coffee that cost $8.36 per pound after buying a coffee she had $26.85 left.

Therefore, base on the card, the number of pounds of coffee she bought can be calculated as follows;

Hence,

let

the amount of coffee she bought in pounds = x

Hence,

70 = 8.36x + 26.85

70  - 26.85 = 8.36x

43.15 = 8.36x

divide both sides by 8.36

43.15 / 8.36 = x

The length of the password has to be of 9 characters.

Three of them should be letters, 2 should be symbols from the 11 choices of the symbols and 4 have to be digits.

Any of the following can be repeated in the password,

So, making the combination of 9 characters.

As we know, letters are 26, so, there are 26 choices each for three places.

Also, if 11 symbols are available, then there are 11 choices each are available for the two places and the total number of 10 which are 0 to 9, so, there are 9 choices each for the last four places,

The ratio of the number of girls to the number of adults is 5 : 1.

Ratio is used to compare two or more values together. Ratio shows the frequency of one number compared to the frequency of another number. The sign that is used to represent ratio is :.  

The ratio of the number of girls to the number of adults = number of girls : number of adults

number of girls = 100

number of adults = 20

The ratio of the number of girls to the number of adults = 100 : 20

Express the ratio in its simplest form. To do this, divide both numbers by the greatest common factor of 100 and 20. The greatest common factor of 100 and 20 is 20.

It is not possible to write a linear inequality such that the solution contains only positive values of x and y.

This happens because every line on the coordinate plane must have a y-intercept and/or an x-intercept. When the line crosses an axis, either the variable x or y changes its sign.

Answer:

x = 30°

Step-by-step explanation:

The angles of a pentagon add up to 540°

Make an equation adding up the angles to equal 540°

x + 4x + 4x + 135° + 135° = 540°

Simplify

9x = 270°

Divide

x = 30°

First step is to write the equation in slope-intercept form

[tex]x - 5y = 5\\-5y = -x+5[/tex]      To make simplification easier, multiply negative to both sides

[tex]5y = x-5\\[/tex]  Now, you must divide 5 to both sides to isolate the variable

[tex]y = \frac{x}{5} - 1[/tex] To tell the slope more easily, turn [tex]\frac{x}{5}[/tex] into [tex]\frac{1}{5} x[/tex]

To rewrite the equation: [tex]y = \frac{1}{5} x - 1[/tex]

Now, you are able to see the slope(m) being [tex]\frac{1}{5}[/tex]

Next, you use the formula y=mx+b to solve for b (replace your newly found slope and points "x" and "y"

[tex]20 = (\frac{1}{5} *-15) + b\\20 = -3 + b\\b -3 = 20\\b = 23[/tex]
