An inequality which is represented by the number line above is: x < -7.

A number line can be defined as a type of graph with a graduated straight line which contains both positive and negative numbers (numerical values) that are placed at equal intervals along its length.

In Mathematics, there are four (4) rules that are generally used to write an inequality and these include the following:

Next, we would apply the aforementioned rules to write the solution to the inequality shown in the number line above:

x < -7

The value of x in the solution set is x = 4

The system of inequalities is given as

3x + 4 < 9

-x + 6 ≥ -3

The first step is to solve for x in both inequalities in the system of inequalities

So, we have

3x + 4 < 9

3x < 5

Divide by 3

x < 5/3

Also, we  have

-x + 6 ≥ -3

-x ≥ -9

Divide by -1

x ≤ 9

So, we have

x < 5/3 and x ≤ 9

x ≤ 9 is a superset of x < 5/3

So, we have

x ≤ 9

This means that the values of x do not exceed 9

An example of this value (from the options) is 4

Answer:

He would have $235

Step-by-step explanation:

If Tom worked 28 hours and earned $9 per hour he would have 252 dollars. Then if he spent $17 dollars he would have $235

Answer:

235

Explanation:

If Tom worked 28 hours last month, and his hourly rate is $9.

Start by multiplying 9 times 28. 9 × 28 = 252

Faster way I do the math is in my head, what is 9*3=27, Add a zero 9×30=270. 30-2=28;2×9=18, Subtract 270-18=252...

Tom spent $17 of his earnings, $252-$17=$235

Step-by-step explanation:

Answer:

1.) 49 [tex]\frac{3}{4}[/tex] [tex]in^{2}[/tex]      2.) 154.5 [tex]cm^{2}[/tex]

Step-by-step explanation:

These involve finding the area of a rectangular prism.

1.)

A = 2wl + 2lh + 2hw

A = 2(3.25 x 3.5) + 2(3.5 x 2) + 2(2 x 3.25)

A = 2(11.375) + 2(7) + 2(6.5)

A = 22.75 + 14 + 13

A = 49.75

2.)

A = 2wl + 2lh + 2hw

A = 2(4.5 x 8.5) + 2(8.5 x 3) + 2(3 x 4.5)

A = 2(38.25) + 2(25.5) + 2(13.5)

The most appropriate choice for simultaneous linear equation will be given by -

Cost of one notebook is $1.70 and cost of one pen is $0.50

What is simultaneous linear equation?

At first it is important to know about linear equation

Equation shows the equality between two algebraic expressions by connecting the two algebraic expressions by an equal to sign.

A one degree equation is known as linear equation.

Two or more linear equations, which can be solved together to obtain common solution are known as simultaneous linear equation.

Here,

Let the cost of one notebook be $x and the cost of one pen be $y

John spent $10.50 on 5 notebooks and 4 pens.

So,

5x + 4y = 10.50 ........... (1)

Ariana spent $7.80 on 4 notebooks and 2 pens

So,

4x + 2y = 7.80 ............ (2)

Multiplying equation (2) by 2,

8x + 4y = 15.60 ............ (3)

Subtracting (1) from (3),

3x = 5.10

[tex]x = \frac{5.10}{3}[/tex]

[tex]x =[/tex] $[tex]1.70[/tex]

Putting the value of x in (1)

[tex]5 \times 1.70 + 4y = 10.50\\8,50 +4y = 4y = 10.50\\4y = 10.50 - 8.50\\4y = 2\\y = \frac{2}{4}[/tex]

y = $[tex]0.50[/tex]

The son mowed most of the lawn

7/20 of the lawn still needs to be mowed

Size of the lawn mowed by Miss Jones = 1/4

Size of the lawn mowed by her son = 2/5

To know who mowed the most lawn, find the LCM of the denominators

The LCM of 4and 5 = 20

Make the denominators of both fractions to be 20

Size of the lawn mowed by Miss Jones = 1/4 x 5/5 = 5/20

Size of the lawn mowed by her son = 2/5 x 4/4 = 8/20

Since 8/20 > 5/20, Miss Jone's son mowed more part of the lawn than Miss Jone

How much of the lawn still needs to be mowed:

Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan. The daily interest rate, the principle, and the number of days between payments are multiplied to calculate simple interest. Simple Interest (S.I.) is a way for figuring out how much interest will accrue on a specific principal sum of money at a certain rate of interest. Because simple interest keeps total interest payments lower than compound interest, it is better for borrowers. Simple interest is used in the monthly amortization of auto loans and retailer instalment loans. As the loan balance decreases with each monthly payment, so does the interest.

Given Data

Principal = $939

Time = 12 months

Rate = 11%

Simple interest = P(R)(T)

Simple interest = [tex]\frac{939(1)(11)}{100}[/tex]

Simple interest = 103.29

The required probability would be 65.78% that at most 14 returns will pass the audit.

The probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

P(Passed the audit) = 0.931

Number of tax returns = 15

We must determine the probability that no more than 14 returns will pass the audit.

⇒ P(X⇒14)

P(X⇒14) = 1 - P(X>14) =1 - P(X=15)

Binomial distribution probability, which can be computed as will be used in this case

⇒ P(X=n IN,p) = P(X=15| 15,0.931)

⇒  15C15 (0.931¹⁵) (1-0.931)⁽¹⁵⁻¹⁵⁾

⇒  10.34221 × 10

⇒ P(X⇒14) = 1 - P(X>14)=1 - P(X=15) = 1 -0.3422 = 0.6578

Using the continuity concept, it is found that the function is continuous on the following interval:

C. (0, 1).

A function f(x) is continuous at x = a if it is defined at x = a, and the lateral limits are equal, that is:

[tex]\lim_{x \rightarrow a^-} f(x) = \lim_{x \rightarrow a^+} f(x) = f(a)[/tex]

3/7 (the correct option is not there)

EXPLANATION

There are 7 red balls and 3 white balls in the bag.

To find the probability of Doug being the first to draw the white ball, we have to assume that Andrew, Betsy and Cam all draw red balls.

There are a total of 10 balls there.

After Andrew Betsy and Doug pick their balls, there will be 7 balls left, that is:

4 red balls and 3 white balls.

Ther probaility of Doug picking the white ball will therefore be the number of white balls divided by the total number of balls.

That is:

P(Doug) = 3/7

That is the probability that Doug will win the $160.

The value of x is 8 cm.

The area of a rectangle is the space occupied by the rectangle inside its perimeter. A rectangle's area is calculated by multiplying its length by its width.

Given:

Length of rectangle = 20 cm

Width of rectangle= x cm

Area of rectangle = length × width

                             = 20x cm²

The dimensions of the smaller rectangle cut out of it are,

Length = 16cm

Width = x-3

Area of the smaller rectangle = length × width

                                                 = 16(x - 3) cm²

The area of the shaded portion will be equal to the difference between both areas which is given as 80 square centimeters.

20x - 16(x-3) = 80

Now, we need to solve this equation to obtain the value of x.

20x - 16x + 48 = 80

4x = 80 - 48

4x = 32

x = 32/4

x = 8

Therefore, the value of x is 8 cm.

Savannah's grade percentage in the class so far is 92.28%.

Percentage is a measure of frequency that is used in mathematics. The sign that represents percentage is %. In order to convert a number to percentage, multiply the fraction of that amount by 100 or by the given percentage.

Savannah's grade percentage can be determined by adding her percentage score in each component that makes up the total grade.

Percentage score in quizzes = (score obtained / maximum score) x percentage allocated to quizzes

(118 / 150) x 15% = 11.80%

Percentage score in the three exams = (average of the three scores / maximum score) / percentage allocated to exams

Average of the three scores = (73+ 89 + 97) / 3 = 86.33

(86.33 / 100) x 55% = 47.48%

Percentage score in the project = (score in the project / maximum points) x percentage allocated to project

(28 / 25) x 25% = 28%

Percentage score in attendance = 5%
