What is the answer to, (4-1) . n = n . _

Answer:

5/8

Step-by-step explanation:

if I understand correctly the problem is

(2*X)-(3/4)=1/2

to solve for x we need to isolate it, the first step in doing so is getting rid of the 3/4

2*X-3/4+3/4=1/2+3/4

simplify

2*X=1 1/4

the next step is getting rid of the 2

(2*X)/2=(1 1/4)/2

simplify

X=5/8

Answer:

Monthly Salary = $2,600

Step-by-step explanation:

Monthly rent on monthly salary = 25%

Monthly rent = $650.

To determine the monthly sale, we have to use the unitary method.

25% monthly rent on monthly salary means out of $100, Deja spends $25 on her rent.

Therefore,

Deja spends $25 on her rent, when the monthly salary   = $100

Deja spends $1 on her rent, when the monthly salary      = [tex]\frac{100}{25}[/tex]

Deja spends $650 on her rent, when the monthly salary = [tex]\frac{100*650}{25}[/tex]

= [tex]\frac{65000}{25}[/tex]

= $2,600

Her monthly salary is $2,600.

The original selling price of the ski set is $585.71.

Step 1: Determine the final sale price after the first markdown

The one-day sale price of the ski set is $328, and the first markdown is 20%. To find the final sale price after the first markdown, we can set up the equation:

0.80 × Original Price = $328

Solving for the original price, we get:

Original Price = $328 / 0.80 = $410

Therefore, the final sale price after the first markdown is $410.

Step 2: Determine the original selling price

The final sale price after the first markdown is $410, and the second markdown is 30%. To find the original selling price, we can set up the equation:

0.70 × Original Price = $410

Solving for the original price, we get:

Original Price = $410 / 0.70 = $585.71

Therefore, the original selling price of the ski set is $585.71.

Answer:

[tex]n = 3[/tex]

Step-by-step explanation:

Given:

The equation given is:

[tex]p^3q^2(p^4q^n\times \frac{r^3}{r^{-4}})=p^7q^5r^7[/tex]

We simplify the given equation using the following law of indices:

[tex]a^m\times a^n=a^{m+n}\\\frac{a^m}{a^n}=a^{m-n}[/tex]

Therefore,

[tex]p^{3+4}q^{n+2}\times r^{3-(-4)})=p^7q^5r^7\\p^7q^{n+2}r^7=p^7q^5r^7\\q^{n+2}=q^5[/tex]

Since the base on both the sides is same, therefore, their exponents must also be same. This gives,

[tex]n+2=5\\n=5-2\\n=3[/tex]

Therefore, the value of 'n' is 3.

Answer:

x ≤ 3

This is because it is a closed circle.

To find the cost of 24 candy bars, calculate the cost per candy bar (found by dividing $20 by 16, equaling $1.25) and multiply it by 24. Therefore, 24 candy bars would cost $30.

The subject of the question involves unit pricing, a common concept in mathematics. To find the cost of 24 candy bars, first identify the cost per candy bar, then multiply this unit price by the number of candy bars in question.

From the question, we know that 16 candy bars cost $20. So the unit price, or cost per candy bar, is $20 divided by 16, which equals $1.25.

Therefore, the cost of 24 candy bars would be $1.25 (the cost per candy bar) multiplied by 24 (the number of candy bars), which equals $30. Hence, 24 candy bars would cost $30.

Answer:

C. y +3 = x +3

Step-by-step explanation:

We need to find in below option x has direct variation with y.

We solve for each;

A. [tex]2y = 3x-7[/tex]

From above equation we can state that 2 times y is equal to 7 less than 3 times of x.

Hence it doesn't represent direct variation.  

B. [tex]y-4 = x+6[/tex]

Solving above expression we get;

[tex]y-4 = x+6\\y = x+6+4\\y=x+10[/tex]

From above equation we can state that y is equal to 10 more than x.

Hence it doesn't represent direct variation.

C. [tex]y+3 = x+3[/tex]

Solving above expression we get;

[tex]y+3 = x+3\\y = x+3-3\\y=x[/tex]

From above equation we can state that y is equal to x.

Hence it represent direct variation.

D. [tex]4y+1 = 4x-1[/tex]

Solving above expression we get;

[tex]4y+1 = 4x-1\\4y = 4x-1-1\\4y=4x-2[/tex]

From above equation we can state that 4 times y is equal to 2 less than 4 times of x.

Hence it doesn't represent direct variation.

Hence the Answer which represent direct variation of x and y is,

C. [tex]y+3 = x+3[/tex]

To find the x-intercept of the linear equation y = 1/4x + 5/4, substitute y = 0 into the equation and solve for x. The x-intercept is -5.

To find the x-intercept of the graph of the equation y = 1/4x + 5/4, we need to set the y-value to 0 and solve for x.

So, by substituting y = 0 into the equation, we get 0 = 1/4x + 5/4.  

Now, we can solve for x by isolating x on one side of the equation. Subtracting 5/4 from both sides gives us -5/4 = 1/4x. Multiplying both sides by 4 gives us -5 = x, or x = -5.

Therefore, the x-intercept of the graph is -5.

Answer:

$60

Step-by-step explanation:

11 identical pairs of Air Jordan cost $660.

To find the cost of one pair, you have simply to divide the total amount paid by the total number of pairs.

Total amount paid = $660

Total number of pairs = 11

The cost of one pair [tex]=\$660 : 11=\$60[/tex]

To find the cost of one pair of Air Jordan sneakers from the total cost of 11 pairs, divide the total cost ($660) by the number of pairs (11), which equals $60 per pair.

The question concerns determining the cost of one pair of Air Jordan sneakers given the total cost for 11 pairs. This is a basic division problem that falls under the category of arithmetic in mathematics. To find the cost of one pair, divide the total cost by the number of pairs. Here is how the calculation is done step-by-step:

Therefore, the cost for one pair of Air Jordan sneakers is $60.
