Answer:

[tex]x = 6[/tex]

Step-by-step explanation:

Analyzing the statement one after the other:

Half a number x: [tex]\frac{1}{2}x[/tex]

Equals to: [tex]=[/tex]

9 less than twice that same number: [tex]2x - 9[/tex]

Bring them together, we have:

[tex]\frac{1}{2}x = 2x-9[/tex]

Collect Like Terms

[tex]\frac{1}{2}x - 2x= -9[/tex]

[tex]\frac{x}{2} - 2x= -9[/tex]

[tex]\frac{x - 4x}{2} = -9[/tex]

[tex]\frac{ - 3x}{2} = -9[/tex]

Multiply through by 2

[tex]2 * \frac{ - 3x}{2} = -9 * 2[/tex]

[tex]- 3x = -18[/tex]

Divide through by -3

[tex]x = 6[/tex]

Answer:

4/5

Step-by-step explanation:

There are four quadrants in a coordinate geometry.

The value of cos(A - B) is 84/85

The given parameters are:

[tex]\mathbf{cos(A) = \frac{15}{17}}[/tex]

[tex]\mathbf{cos(B) = \frac{4}{5}}[/tex]

Using trigonometry ratio, we have:

[tex]\mathbf{sin^2(A) + cos^2(A)= 1}[/tex]

Substitute [tex]\mathbf{cos(A) = \frac{15}{17}}[/tex]

[tex]\mathbf{sin^2(A) + (\frac {15}{17})^2 =1}[/tex]

Expand

[tex]\mathbf{sin^2(A) + \frac{225}{289} =1}[/tex]

Collect like terms

[tex]\mathbf{sin^2(A) =1 - \frac{225}{289}}[/tex]

Evaluate fraction

[tex]\mathbf{sin^2(A) =\frac{64}{289}}[/tex]

Take square roots of both sides

[tex]\mathbf{sin(A) =\pm\frac{8}{17}}[/tex]

The angle is in the fourth quadrant.

So, we have:

[tex]\mathbf{sin(A) =-\frac{8}{17}}[/tex]

Also,

Substitute [tex]\mathbf{cos(B) = \frac{4}{5}}[/tex] in [tex]\mathbf{sin^2(B) + cos^2(B)= 1}[/tex]

[tex]\mathbf{sin^2(B) + (\frac 45)^2= 1}[/tex]

[tex]\mathbf{sin^2(B) + \frac{16}{25}= 1}[/tex]

Collect like terms

[tex]\mathbf{sin^2(B) = 1 - \frac{16}{25}}[/tex]

Simplify fraction

[tex]\mathbf{sin^2(B) = \frac{9}{25}}[/tex]

Take square roots

[tex]\mathbf{sin(B) = \pm \frac{3}{5}}[/tex]

The angle is also in fourth quadrant

So, we have:

[tex]\mathbf{sin(B) = - \frac{3}{5}}[/tex]

To calculate cos(A - B), we make use of:

[tex]\mathbf{cos(A - B) = cos(A)cos(B) + sin(A)sin(B)}[/tex]

So, we have:

[tex]\mathbf{cos(A - B) = \frac{15}{17} \times \frac{4}{5} + \frac{-8}{17} \times \frac{-3}{5}}[/tex]

Evaluate

[tex]\mathbf{cos(A - B) = \frac{60}{85} + \frac{24}{85}}[/tex]

Take LCM

[tex]\mathbf{cos(A - B) = \frac{60+24}{85}}[/tex]

[tex]\mathbf{cos(A - B) = \frac{84}{85}}[/tex]

Hence, the value of cos(A - B) is 84/85

Answer:

Tell them you don't take cash

Answer:

Total tickets = 70

Total cost = $550

Adult's ticket = $9

Child's ticket = $5

Difference = 9 - 5 = $4

Assume all 70 are child's tickets

5 x 70 = 350

But the total cost was 550

550 - 350 = $200

The $200 must have come from Adult's tickets, which has a difference of $4.

200 ÷ 4 = 50

So there are 50 adult's tickets.

70 - 50 = 20

And there are 20 child's tickets.

Answer:

by 25%

Step-by-step explanation:

We can assume that the company originally had 100 stores and it plans to keep only 60 open after two years. If it was able to close 20 stores during the first year, the total number of stores remaining open was 100 - 20 = 80. Since it needs to decrease the number of stores to 60, it must reduce the number of stores by 20/80 = 0.25 or 25%.

Answer:

x = 10

Step-by-step explanation:

Assuming the 2 figures are similar, then the ratios of corresponding sides are equal, that is

[tex]\frac{5}{x}[/tex] = [tex]\frac{4}{8}[/tex] ( cross- multiply )

4x = 40 ( divide both sides by 4 )

x = -4

General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define equation

x + 13 = 9

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 9 does indeed equal 9.

∴ x = -4 is a solution of the equation.

Answer:

x=-4

Step-by-step explanation:

So when solving a one-step algebraic equation you need to remember what you do to one side you have to do to the other side. In the problem x + 13 = 9 you need to subtract 13 from both sides to isolate x. So your problem should look like x = 9 - 13. Now all you have to do is solve 9 - 13 which is -4. So x = -4.

Answer: it’s 12

Step-by-step explanation:

If x and y are both integers, then the expression equivalent to ll x - y ll is,

ll y -x ll.

Here,

Given expression is,  ll x - y ll

What is modulus function?

The modulus function gives the magnitude or absolute value of a number irrespective of the number being positive or negative.

Now,

Let x = 2 and y = 1

Hence, ll x - y ll = ll 2 - 1 ll = 1

And, ll y - x ll = ll 1 - 2 ll = 1

So, Option A is true.

Hence, If x and y are both integers, then the expression equivalent to llx - y ll is, ll y -x ll.

Answer:

W - Y > H

Or

H < W - Y

Step-by-step explanation:

From the word problem/ information given from the problem, we can formulate a full inequality:

[tex]\frac{W > Y+H}{P}[/tex]

And we are trying to solve for H:

What we must do is solve by following the process of PEMDAS

P - () (Parenthesis)

E - [tex]x^{2}[/tex] (Exponents)

M - x (Multiply)

D - [tex]\frac{x}{y}[/tex] (Division)

A - + (Addition)

S - [-] (Subtraction)

1) Look through PEMDAS until you notice one:

We find that there is Division!

In order to get one step closer to finding H, we must do the opposite of dividing which is multiplying:

P([tex]\frac{W > Y+H}{P}[/tex])

This will cancel out P, leaving you with:

[tex]{W > Y+H}[/tex]

2) Now we must get H alone by subtracting Y on both sides:

[tex]{W > Y+H}\\[/tex]

-Y  - Y

---------------

W - Y > H

Your final answer is W - Y > H

Hope this helps you!

You graph it here

Answer:

Step-by-step explanation:

Alright, so this is basically just another equation, but then you see the greater than or equal to sign. How do I solve this? You may be asking. Well, treat it like an equation and worry about the sign later.

4x - 5 [tex]\geq[/tex] 7

Solve for x.

Add 5 to each side, then divide by 4 to each side.

4x [tex]\geq[/tex] 12

x [tex]\geq[/tex] 3  <----This is the answer.

Now for the graph. Look at the picture below:

That's what the graph should look like. Since it has a greater than or equal to sign, the line will be solid.

The graph is basically saying that anything that is greater than 3 (including 3) is counted, which is why that entire right side of 3 is shaded in.

Also, the way you should technically graph it is on a number line. So make a number line.

     -2   -1     0     1     2    3     4     5    6    7     8    9    10

<-----|-----|-----|-----|-----|-----€-----|-----|-----|-----|-----|-----|-----|----->

(Pretend € is the filled in dot).

So, the above number line is what it should look like when graphed. The € circle is filled in because we are including the 3.

Answer:

-4/9 is a rational number

Step-by-step explanation:

Rational numbers are the numbers you can make by dividing one integer by another, so in other words a fraction.

Answer

4/9 belongs to rational numbers (D).

Explanation

(Lol moderator deleted everyone's answers so I'm gonna answer).

First I'll give you a definition of each choice.

Integers: Integers don't include decimals or fractions. Integers are positive and negative numbers. So basically it's this; (..., -3, -2, -1, 0, 1, 2, 3, ...). The '...' means numbers from infinity to the next number. I hope this makes sense Imao.

Whole numbers: whole numbers are integers, except they don't include negative numbers. Whole numbers include 0 (zero)... (0, 1, 2, 3, ...)

Natural numbers: natural numbers are whole numbers but they don't include 0 (zero)... (1, 2, 3, ...)

Rational numbers: rational numbers are numbers that can be expressed as a fraction. This includes repeating decimals such as 0.333 repeating. Rational numbers also include integers, because if you put the number over one, that is a fraction. Rational numbers are basically every number except for the radicals of some numbers (such as the square root of 3) and pi.

So now let's just see which one 4/9 is.

Well, 4/9 is not an integer, whole number, or natural number because it is a fraction.

But 4/9 can be expressed as a fraction (well, it already is one) meaning it is a rational number.
