Solving the problem using basic algebra, the total number of hamburgers that were sold on Saturday can be obtained as 108 hamburgers.

The word problem that has been formulated in the question falls under the basic discipline of mathematics known as algebra.

Algebra is a branch of mathematics that deals with mathematical variables and the rules for manipulating these variables to solve diverse mathematical problems.

Let the total number of hamburgers sold be x.

In the question, it is given that the total number of cheeseburgers sold would be 3 times the number of hamburgers sold. Then the number of cheeseburgers sold would be 3x.

It is also given that the total number of hamburgers and cheeseburgers sold together is 432.

Using these data, the equation can be formulated as x + 3x = 432.

As x and 3x are variables of the same nature, which is x, they can be added to obtain the answer as 4x, hence the equation becomes

4x = 432. Solving for x, we get

x = 432 ÷ 4

x = 108.

The equations that have the same solutions are

15x - 60 = 120

3x = 36

x - 4 = 8

Options A, B, and D

Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.

We have,

3x - 12 = 24

Add 12 on both sides.

3x = 24 + 12

3x = 36

Divide both sides by 3.

x = 12

The solution for 3x - 12 = 24 is 12.

Now,

15x - 60 = 120

15x = 120 + 60

15x = 180

x = 180/15

x = 12 _____(1)

3x = 12

x = 12/3

x = 4 ______(2)

3x = 36

x = 36/3

x = 12 ______(3)

x - 4 = 8

x = 8 + 4

x = 12 ______(4)

12x - 12 = 24

12x = 24 + 12

12x = 36

x = 36/2

x = 19 ______(5)

From (1), (2), (3), (4), and (5) we see that,

15x - 60 =120, 3x = 36, and x - 4 = 8 has the same solution as 3x - 12 = 24.

Thus,

The equations that have the same solutions are

15x - 60 = 120

3x = 36

x - 4 = 8

Options A, B, and D

The average of the three hidden prime numbers is 5, as the sum of any two of the numbers is equal to 10, and since all three numbers are prime, the only possible values are 3, 5, and 7.

3 + 5 + 7 = 15

15/3 = 5

The average of the three hidden prime numbers is 5. This means that the sum of any two of the numbers on the cards must be equal to 10. Since all three numbers are prime,as the sum of any two of the numbers is equal to 10 the only possible values are 3, 5, and 7. Therefore, the three numbers on the hidden sides of the cards are 3, 5, and 7. To calculate the average, we add the three values together and divide by three. 3 + 5 + 7 = 15, and 15 divided by 3 is 5. Therefore, the average of the hidden prime numbers is 5.

Answer:

Javier’s account has $282.5 at the end of the three months.

Step-by-step explanation:

final = initial - 7.5x

initial is the initial amount of money in the account, so 305. x is the number of months that have passed. Since Javier doesn't deposit any more money durning that time, the amount in the bank will always be less then 500 we don't have to consider anything else. We just sub initial with 305 and x ( the number of months) with 3 to get the answer. So,

final = 305 - 7.5 * 3 = 282.5

In Mathematics and Geometry, a function is an equation which defines and represents the relationship that exist between two or more variables.

Part a.

By critically observing the graph of f(x) and g(x) shown in the image attached below, the corresponding output values are as follows:

f(0) = 3.

g(2) = 2.

Part b.

The values of x for which f(x) is equal to g(x) are x = -2 and x = 2;

In a shuffleboard court where three similar triangles are formed, the corresponding angle that is congruent to angle A is angle H.

In the given information, it is stated that the shuffleboard court forms three similar triangles. When triangles are similar, it means that their corresponding angles are congruent, and their corresponding sides are in proportion.

Among the given angles and sides, we are asked to find the corresponding side or angle that is congruent to angle A. Since the triangles are similar, we can conclude that the corresponding angle to angle A in another triangle will also be congruent. In this case, the corresponding angle that is congruent to angle A is angle H.

Therefore, angle A and angle H are congruent in the similar triangles formed by the shuffleboard court.

The length of the diameter of circle is 12 feet .

Given equation of circle,

(x - 13)² + (y + 20)² = 36

Now let us see the standard form of equation of circle,

Since, the equation of a circle is,

\({(x-h)^2} + (y - h)^2 = r^2\)

Where,

(h, k) is the center of the circle,

r = radius of the circle,

Comparing it with the standard form  the values of h, k , r are:

Here,

(h, k) = (13, -20)

r²  = 36

r = 6 units,

Now,

Diameter is double than that of radius.

The correct formula that defines an arithmetic sequence is option d) tn = 5n + 14.

An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms remains constant. In other words, each term can be obtained by adding a fixed value (the common difference) to the previous term.

In option a) tn = 5 + 14, the term does not depend on the value of n and does not exhibit a constant difference between terms. Therefore, it does not represent an arithmetic sequence.

Option b) tn = 5n² + 14 represents a quadratic sequence, where the difference between consecutive terms increases with each term. It does not represent an arithmetic sequence.

Option c) tn = 5n(n+14) represents a sequence with a varying difference, as it depends on the value of n. It does not represent an arithmetic sequence.

Option d) tn = 5n + 14 represents an arithmetic sequence, where each term is obtained by adding a constant value of 5 to the previous term. The common difference between consecutive terms is 5, making it the correct formula for an arithmetic sequence.

Step-by-step explana

There is no point (x, y) that satisfies both given equations simultaneously.

The system of equations is given as follows:

3x - 3y = -4

x - y = -3

Let's solve the second equation for x in terms of y:

x - y = -3

x = y - 3

Substitute x = y - 3 into the first equation:

3x - 3y = -4

3(y - 3) - 3y = -4

3y - 9 - 3y = -4

-9 = 5

The last step is not true, so the system has no solution.

Therefore, there is no solution to the system of equations 3x - 3y = -4 and x - y = -3.

This means that there is no point (x, y) that satisfies both equations simultaneously.

Plug 6 and 4 into the problem-

6(6 + 2)/4

6(8)/4

48/4 = 12

Hey there!

6(g + 2) / h

= 6(6 + 2) / 4

= 6(8) / 4

= 8(6) / 4

= 8 + 8 + 8 + 8 + 8 + 8 / 4

= 16 + 16 + 16 / 4

= 32 + 16 / 4

= 48 / 4

= 48 ÷ 4 / 4 ÷ 4

= 12 / 1

= 12 ÷ 1

= 12

Therefore, your answer is: 12
