From the question, we have the following parameters that can be used in our computation:

600 divided by 5

When represented as an equation, we have

600 divided by 5 = 600/5

Divide 7 by 4

So, we have the following result

600 divided by 5 = 120

Using the above as a guide, we have the following:

the result is 120

Answer:

x = 1 and y = 4

Step-by-step explanation:

5x+2y+2x+6y = 39

7x+8y = 39

Trial and error method:

the answer that satisfies the equation are: x = 1 and y = 4

Hope this helps.

Good Luck

Answer:

(1, 4 )

Step-by-step explanation:

Given the 2 equations

5x + 2y = 13 → (1)

2x + 6y = 26 → (2)

Multiplying (1) by - 3 and adding to (2) will eliminate the term in y

- 15x - 6y = - 39 → (3)

Add (2) and (3) term by term to eliminate y

- 13x = - 13 ( divide both sides by - 13 )

x = 1

Substitute x = 1 into either of the 2 equations and evaluate for y

Substituting into (1)

5(1) + 2y = 13

5 + 2y = 13 ( subtract 5 from both sides )

2y = 8 ( divide both sides by 2 )

y = 4

Solution is (1, 4 )

Answer:

x = -8

Step-by-step explanation:

[tex]6x - 3 = -51?\\To - find-x- collect-like-terms.\\6x=-51+3\\6x =-48\\Divide-both-sides-of-the-equation-by-6\\\frac{6x}{6} = \frac{-48}{6} \\x = -8[/tex]

Answer:

234

Step-by-step explanation:

The consecutive terms of the sequence have a common difference d

d = 17 - 10 = 24 - 17 = 7

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 10 and d = 7 , thus

[tex]a_{33}[/tex] = 10 + (32 × 7) = 10 + 224 = 234

Answer:

Total number of stamps is 600

Number of stamps collected from Europe is 150

Number of stamps collected from America is 200

Step-by-step explanation:

1/3 of stamps collected are from America

1/4 of stamps collected are from Europe

While 250 stamps are from Africa and Asia

Now what this means is that the fraction remaining when we subtract the sum of 1/3 and 1/4 is what is equal to 250

Firstly, let’s say the total stamp is x

Now the fraction of x equal to 250 would be ;

1-1/3-1/4 = 1-(1/3 + 1/4) = 1-(7/12) = 5/12

Now, 5/12 of x = 250

5/12 * x = 250

5x = 12 * 250

5x = 3,000

x = 3,000/5

x = 600 stamps

Thus, the total number of stamps collected is 600

The number collected from America is 1/3 * 600 = 200

The number collected from Europe is 1/4 * 600 = 150

Answer:

x = 121°

Step-by-step explanation:

The lower left interior angle of the triangle is adjacent to 115° and are supplementary, thus

interior angle = 180° - 115° = 65°

The angle round a point is 360°

The vertex interior angle = 360° - 304° = 56°

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

x is an exterior angle of the triangle, thus

x = 65° + 56° = 121°

Answer:

The mass of the chocolate will be between 2.42 ounces and 2.58 ounces, the absolute value inequality is:  [tex]|mass - 2.5| < 0.08[/tex]

Step-by-step explanation:

The ideal mass of the chocolate is 2.5 ounces, although it can vary by 0.08 ounces, this variation can occur for greater masses and lesser ones. Therefore the actual mass of the each chocolate will sit between the ideal mass minus 0.08 and the ideal mass plus 0.08. Therefore we can construct the following inequality:

[tex]-0.08 < mass + 2.58 <0.08\\ |mass - 2.5|< 0.08\\[/tex]

The mass of the chocolate will be between 2.42 ounces and 2.58 ounces, the absolute value inequality is:  [tex]|mass - 2.5| < 0.08[/tex]

Answer:

Step-by-step explanation:

|x| fails the horizontal line test, so these two functions as presented are NOT inverses of one another.

However, if we look ONLY at x < 0, the functions ARE reciprocals; a horizontal line passes through the graph of |x| only once.

Answer:

the  mean and standard error of the mean are 200 and 2 respectively.

Step-by-step explanation:

Given that ;

the sample size n = 81

population mean μ = 200

standard deviation of the infinite population σ = 18

A population  is the whole set of values, or individuals you are interested in, from an experimental study.

The value of population characteristics such as the  Population mean (μ), standard deviation (σ) are said to be known as the population distribution.

From the given information above;

The sample size is large and hence based on the central limit theorem the mean of all the means is same as the population mean 200.

i.e

[tex]\mu = \bar \mu_x[/tex] = 200

∴ The mean = 200

and the standard error of the mean can be determined via the relation:

[tex]\mathbf{standard \ error \ of \ mean = \dfrac{\sigma}{\sqrt {n}}}[/tex]

[tex]\mathbf{standard \ error \ of \ mean = \dfrac{18}{\sqrt {81}}}[/tex]

[tex]\mathbf{standard \ error \ of \ mean = \dfrac{18}{9}}[/tex]

[tex]\mathbf{standard \ error \ of \ mean =2}[/tex]

Therefore ; the  mean and standard error of the mean are 200 and 2 respectively.

Answer:

Step 2.

Step-by-step explanation:

When you have a coefficient on a side of the equation that you need to get rid of, you must divide by the number. For example, in the problem:

3(x+8)² = 75

Here, you need to divide both sides by '3' instead of multiplying, which was done instead. Then you get:

(x+8)² = 25.

Therefore, his mistake was made at Step 2.

Answer: 232 pages

Step-by-step explanation:

Total digits = 588

1 digit page number:

1 to 9 = 1 × 9 = 9

Number of pages = 9/1 = 9

2 - digit page number :

10 - 99 = 2 × 90 = 180

Number of pages = 180/2 = 90

3 - digit page number :

588 - (9 + 180) = 588 - 189 = 399

Number of pages with 3 - digits = 399/3 = 133

Therefore, the total number of pages the book has is :

(9 + 90 + 133) = 232 pages

 [tex]7\frac{1}{2}[/tex] bags of coffee will last for 9 days.

A unit rate means a rate for one of something.

Answer:

OC. $57.28

Step-by-step explanation:

It depends on how much she sells them for.

Let's say Anne sells them for $x.

Then her profit is:

8x-(8*7.16)

=8x-57.28

To make a minimum to at least make even is $57.28 and sell for $7.16 a piece.

Anne makes a profit of $57.28 on the sale of these 8 canvases. which is the correct answer would be option (C).

The profit is equal to the difference between the selling price and the original cost price.

Anne purchases art supplies for her business from a wholesaler. She spends $7.16 on eight 16 by 20-inch canvases.

To calculate the profit that Anne makes on the sale of these 8 canvases, you need to know the price at which she sells them and the cost of buying them from the wholesaler. If the cost of each canvas is $7.16 and she buys 8 of them, the total cost of the canvases is :

⇒ 8 × $7.16

Apply the multiplication operation and we get

⇒ $57.28.

Therefore, she makes a profit of $57.28 on the sale of these 8 canvases.

Hence, the correct answer would be an option (C).
