The solution of the inequality ( - 5 / 2 ) ( 3x- 2 )< 6 - 2x. will be x < ( 18 / 11 ).

inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.

Given inequality will be solved as below:-

( - 5 / 2 ) ( 3x - 2 ) < 6 - 2x

Multiply the other hand by 2 and solve further.

( - 5  ) ( 3x - 2 ) < 2 ( 6 - 2x )

( - 5  ) ( 3x - 2 ) < ( 12 - 4x )

Take like terms to the same side and solve.

-15x + 30 < 12 - 4x

-15x + 4x < 12 - 30

-11x < - 18

x < 18 / 11

Therefore, the solution of the inequality ( - 5 / 2 ) ( 3x- 2 )< 6 - 2x. will be x < ( 18 / 11 ).

Answer:

x=-1.5

Step-by-step explanation:

To solve for x, you need to rearrange so the x is on one side of the "=" by itself.

So To do that, first you need to subtract 1/4 on both sides of the "=". This leaves you with 1/2+x=-3/4-1/4. You can simplify the -3/4-1/4 to -1 (-4/4). So, you now have 1/2+x=-1.

The next step is to subtract 1/2 on both sides of the "=". This leaves you with x=-1-1/2. Again, you can simplify the -1-1/2 to -3/2 which can be written as -1.5. So, you now have x=-1.5, which is the final answer.

The question may ask you to write your answer in the form of a fraction, in which case your answer x=-3/2. If the questions wants it written as a mixed number, your answer would be -1 1/2.

Answer:

1/4

Step-by-step explanation:

1. To find the slope, you can use the formula [tex]\frac{rise}{run}[/tex] to find it!

2. Rise means how many units you go up and down from point to point, and run means how far you go left or right from point to point.

3. Given the statement above, the rise would be 1, and the run would be 4.

4. Now, since slope is (rise)/(run), the slope is 1/4 because one divided by four is equal to one fourth.

Answer:

7/6

Step-by-step explanation:

7/8 divided by 3/4= 7/8 x 4/3 = 28/24= 7/6

z+6>3 minus 6 from both sides

z>-3

2z<-12 divide both sides by 2

z<-6

Answer:

Area: [tex]5x[/tex], Perimeter: [tex]2x+10[/tex]

Step-by-step explanation:

a)

We know that for any rectangle the area is [tex]l*w[/tex], where [tex]l[/tex] is the length and [tex]w[/tex] is the width.

Because the width is [tex]x[/tex] and the length is [tex]5[/tex], the area is [tex]x*5[/tex] or [tex]5x[/tex].

b)

We know that for any rectangle the perimeter is [tex]2(l+w)=l+w+l+w[/tex], where [tex]l[/tex] is the length and [tex]w[/tex] is the width.

Because the width is [tex]x[/tex] and the length is [tex]5[/tex], the perimeter is [tex]2(x+5)=2x+10[/tex].

So, the answers are [tex]Area:5x,~Perimeter:2x+10[/tex]

Answer:

Each month he will save $ 50

Each month he will spend $1,250

Raking will have $600 in his checking account at the end of the year.

Step-by-step explanation:

1300 - 500 - 750 = $50

$50 x 12 month = $600

The required amount Rakim saves and sped each month is $50 and $1250.

Given that,
Rakim's goal is to have at least $500 in his checking account at the end of the year. The table shows his activity for the month of January. Will Rakim make his goal.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
According to the question,
Total money he has = 1300
Total money spend = 750 + 500 = 1250
Money he save = 1300 - 1250 = 50
For the condition of at end of the year he must have at least $500
So,
Yearly saving = 50 × 12 = $600, which greater than $500.

The required amount Rakim saves and sped each month is $50 and $1250.

Answer:

[tex]y=\frac{7}{2} x -8[/tex]

Step-by-step explanation:

We are given that a line contains these 2 points: (4,6) and (0,-8), in slope-intercept form

Slope-intercept form is given as y=mx+b, where m is the slope and b is the value of y at the y intercept

First, we need to find the slope of the line

The slope can be calculated using the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points

Even though we have 2 points, let's label their values to avoid any confusion and mistakes when calculating:

[tex]x_1=4\\y_1=6\\x_2=0\\y_2=-8[/tex]

Now substitute into the formula

m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m=[tex]\frac{-8-6}{0-4}[/tex]

Subtract

m=[tex]\frac{-14}{-4}[/tex]

Divide

m=[tex]\frac{7}{2}[/tex]

The slope is 7/2

Here is the equation of the line so far:

[tex]y=\frac{7}{2}x + b[/tex]

We now need to find b

As the equation passes through (4,6) and (0,-8), we can use either one of them to help solve for b.

Taking (4,6) for instance:

[tex]6=\frac{7}{2}(4) + b[/tex]

Multiply

[tex]6=14 + b[/tex]

Subtract

-8 = b

The equation therefore is:

[tex]y=\frac{7}{2} x -8[/tex]

Perimeter = 4(2x - 1)

Step-by-step explanation:

Since the Perimeter of a square is 4L, it would be,

(2x - 1) + (2x - 1) + (2x - 1) + (2x - 1) which could also be shortened to 4(2x - 1)

Answer:

P = 4(2x - 1)

Step-by-step explanation:

Given that the side of each square is 2x - 1:

The formula for finding the perimeter of a square is:

P = 4s

where s represents the side of a square.

Substitute the given value for s into the perimeter formula:

s = 2x - 1

P = 4(2x - 1)

Therefore, the perimeter of the square is 4(2x - 1).

Answer:

Mean- 4.9

Median- 4

Mode- 3,4,8

Range- 6

Step-by-step explanation:

The mean of a sequence is the average amount. This is equal to all of the terms' sum divided by the number of terms. So, to find the mean add 2+3+3+4+4+7+8+8, which equals 39. Then, divide by 8 because that is the number of terms. Therefore, the mean is 4.9.

The median is the number in the middle of the sequence. To find the median order the sequence from least to greatest and find the middlemost number. In this case, that is 4.

The mode is the number that appears most often. In this sequence, 3, 4, and 8 all appear twice.

The range is the difference between the minimum and maximum. So, subtract 2 from 8 to get 6.

The amount of milk and flour (x) that he needs to make 40 cookies will be 5/2 cups.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

James uses 1 1/2 cups of milk and 2 1/4 cups of flour for his favorite cookie recipe. This makes 60 cookies.

The amount of milk and flour will be

⇒ 1  1/2 + 2  1/4

⇒ 3/2 + 9/4

⇒ 15/4

Then the amount of milk and flour (x) that he needs to make 40 cookies will be

x / (15/4) = 40 / 60

x = 5/2 cups

The amount of milk and flour (x) that he needs to make 40 cookies will be 5/2 cups.

Answer:

2 + 3/8

Step-by-step explanation:

Therefore we get 19 / 8 = 2 + 3/8 , which is written as 2 3/8 , called a mixed number. To convert 19/8 you do division; 8 into 19 goes 2 times with 3 left over; so 2 3/8.

Out of the weekly amount that Shashi Rimoko makes, a deduction of $37.93 is made for insurance.

The total Medical cost is $9,560 and out of this, the amount paid by Shashi per year is:

= Amount x (1 - percentage paid by restaurant)

= 9,560 x ( 1 - 80%)

= $1,912

The amount he pays for Dental coverage is:

= Amount x (1 - percentage paid by restaurant)

= 172 x (1 - 65%)

= $60.20

The total amount he pays for insurance per year is:

= Medical + Dental

= 1,912 + 60.20

= $1,972.20

The weekly deduction is:

= Year amount / No. of weeks in year

= 1,972.20 / 52

= $37.93

In conclusion, $37.93 is deducted from his paycheck every week.

Answer:

The answer is 86° Fahrenheit.

Step-by-step explanation:

The equation for converting between Fahrenheit and Celsius is °F = 1.8 x °C + 32. So you would just plug 30 in for the °C.

°F = 1.8 x 30° + 32.

°F = 54 + 32

°F = 86°

Answer:

30ºC = 86ºF

Step-by-step explanation:

The temperature T in degrees Fahrenheit (ºF) is equal to 30 degrees Celsius (ºC) times 9/5 plus 32:

T(ºF) = 30ºC × 9/5 + 32 = 86ºF
