-x+3(1 + x) = 3(x +2)

Answers

Answer 1

The given equation, -x + 3(1 + x) = 3(x +2), solved for x, is x = -3

Solving linear equations

From the question, we are to solve the given equation.

The given equation is

-x + 3(1 + x) = 3(x +2)

To solve this equation, we will determine the value of the variable in the equation.

The variable in the equation is x.

Thus, we will solve for x in the equation.

-x + 3(1 + x) = 3(x +2)

Clear the parentheses by applying the distributive property

-x + 3 + 3x = 3x + 6

Collect like terms

-x + 3x - 3x = 6 - 3

-x = 3

Multiply both sides of the equation by -1

-1 × -x = -1 × 3

x = -3

Hence, the value of x is -3

Chris earned $17,000 last year. If the first $25,000 is taxed at 8% and income above that is taxed at 16%, how much does Chris owe in tax?

Answers

well, we know the first $25,000 is taxed at 8%, wait a second!!!!! Chris didn't make 25,000 bucks, he only made $17,000, so he'd be in the range of $0 - $25,000 because $17,000 is in that range, that means he owes 8% of 17,000

[tex]\begin{array}{|c|ll} \cline{1-1} \textit{\textit{\LARGE a}\% of \textit{\LARGE b}}\\ \cline{1-1} \\ \left( \cfrac{\textit{\LARGE a}}{100} \right)\cdot \textit{\LARGE b} \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{8\% of 17000}}{\left( \cfrac{8}{100} \right)17000}\implies 1360[/tex]

The amount Chris owes in tax is $1360.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

The first $25,000 is taxed at 8%.

This means,

Amount from 0 to $25000 is taxed at 8%.

Now,

Chris earned = $17,000

Tax amount.

= 8% of 17,000

= 8/100 x 17,000

= 8 x 170

= $1360

Thus,

The tax amount is $1360.

Answers

The height of the large boxes is 36 inches when the volume of box is 3456 cubic inches.

According to the question,

We have the following information:

A cereal company packs cereal boxes into large cardboard boxes. The large boxes are 12 inches long and 8 inches wide.

Volume of box = 3456 cubic inches

We know that the box is in the shape of cuboid.

Following formula is used to find the volume of cuboid:

Volume = length*width*height

12*8*height = 3456

96*height = 3456

Dividing both sides by 96:

Height = 3456/96

Height of the box = 36 inches

Hence, the height of the large boxes is 36 inches when the volume of box is 3456 cubic inches.

======================

Given function

f(x) = 8 - 4x

Find the indicated values

(a) f(-7)

f(-7) = 8 - 4(-7) = 8 + 28 = 36

(b) f(0)

f(0) = 8 - 4(0) = 8 - 0 = 8

(c) f(4)

f(4) = 8 - 4(4) = 8 - 16 = - 8

Answer:

a) f(-7) = 36 b) f(0) = 8 c) f(4) = -8

Step-by-step explanation:

a) f(-7) = ?

→ f(x) = 8 - 4x

→ f(-7) = 8 - 4(-7)

→ f(-7) = 8 + 28

→ f(-7) = 36

Hence, f(-7) = 36.

b) f(0) = ?

→ f(x) = 8 - 4x

→ f(0) = 8 - 4(0)

→ f(0) = 8 - 0

→ f(0) = 8

Hence, f(0) = 8.

c) f(4) = ?

→ f(x) = 8 - 4x

→ f(4) = 8 - 4(4)

→ f(4) = 8 - 16

→ f(4) = -8

Hence, f(4) = -8.

What is a triangle?

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

In this triangle:

angle W = (3x-24) degrees.

angle C = (4x-11) degrees.

angle T = 2x degrees.

Now,

The sum of the three angles is equal to 180 degrees.

3x - 24 + 4x - 11 + 2x = 180

9x - 35 = 180

9x = 180 + 35

9x = 215

x = 215/9

Now,

The angle W.

= 3x - 24

Step-by-step explanation:
The first thing we need to do is to identify the characteristics of this problem. As you can see, this situation has restriction, limitations on how much money and time they can spend.
In mathematics, restrictions are expressed with inequalities, because it gives us the power to express in terms of more or less than something. When we have this inequality-restrictions problems, it's very helpful to organise all info, so according to the problem, we have:
$ hr
Candidates (x) 400 20
Employees (y) 3600 120
Max. 95000 470
We this organisation, we can easily find expressions, the important thing here is to put together similar variables, money with money and time with time.
So, you can see that, the maximum money they can spend is 95000, and the maximum time is 470 hours, which give us:

As you can see, for money inequality, we used (less than), and for hours we used ''less or equal than''. This difference is because in the text it says that they has less than 95000 (not equal than 95000), and for hours they have at most 470 (meaning that this is a maximum, 470 and below that number).
Therefore, those two inequality express the restriction about money and time limitations for candidates and employees.

Answers

The equation of line passing through the point P(-8,0) that is perpendicular to the line y=-3 is y=0 which can be found out from slope intercept formula.

It is given to us that -

The point is P(-8,0)

The line is represented as y=-3

The point P is perpendicular to the given line.

We have to find out the equation of the line passing through P which is perpendicular to the given line.

We know that the equation of a line is given by -

y = mx + c

where, (x, y) = coordinates of the point

m = slope of the line

c = a constant

Comparing this with the equation of the given line, we have

m=0 and c =-3

This implies that the slope of the perpendicular is also equal to 0.

The slope intercept formula for the perpendicular line can be represented as -

y = mx + c

Using the coordinates of P(-8,0), we have

0 = 0*(-8) +c

=> c = 0.

Thus, the equation of line passing through the point P(-8,0) that is perpendicular to the line y=-3 is y=0.

x is a where 33 can be divided by x and the four value of x is 1,3,11,and 33.

Given that x is a positive where 33 can be divided by x
So x should be less than 33 and a factor of 33
33 can be divded by 3 , 1,11,33
33 can be divded by 1,
33 can be divded by 11
33 can be divded by 33,
So the four value of X s 3,1,11,33.
a where 33 can be divided by x and the four postive value of x is 1,3,11,and 33
