We can see here that according to the agreement, each time Josh jumped the fence, his money would be tripled. Thus, Josh had to pay Sam $54 back for the privilege of jumping.

Josh jumped the fence for the first time. Sam Slick paid Josh the agreed-upon amount, which was triple the initial money Josh had. Then Josh paid Sam $54 back as per the agreement.

We see that Josh jumped the fence for the second time. Sam Slick paid Josh the agreed-upon amount, which was triple the money Josh had after paying Sam $54. After Josh received the payment, he had only $54 left, which was exactly the amount he needed to pay Sam.

Final answer:

The two numbers in question are found by setting up a system of linear equations. The larger number is 39.2, and the smaller number is 27.4, found through substitution and simplification of equations representing their relationship and their sum.

Explanation:

The question involves solving a system of linear equations. Given the smaller number is 2 less than 3/4 the larger number, and the sum of the two numbers is 47, we can set up the following equations where x represents the larger number and y represents the smaller number:

y = ¾ x - 2

x + y = 47

We can substitute equation (1) into equation (2) which gives us x + (¾ x - 2) = 47. Solving for x gives us the larger number, and then y can be determined using either equation (1) or (2).

Following these steps:

x + (¾ x - 2) = 47

1¾ x - 2 = 47

1¾ x = 49

x = 49 / (5/4)

x = 49 * (4/5)

x = 39.2 (larger number)

y = ¾ * 39.2 - 2

y = 29.4 - 2

y = 27.4 (smaller number)

Thus, the two numbers are 39.2 and 27.4.

Final answer:

After dividing the pizza into 3 equal parts twice, Lupita has the exact number of pieces needed for the party, which is 27.

Explanation:

The student's question is about dividing a rectangular pizza into equal parts. Lupita cut the pizza into 3 equal pieces, then each piece into 3 equal parts two more times. To determine if Lupita has enough pieces for 27 people, we can use multiplication to find how many total pieces she has created. The math goes as follows:

First division: 1 pizza is cut into 3 pieces.

Second division: Each of the 3 pieces is cut into 3 pieces, resulting in 3 x 3 = 9 pieces.

Third division: Each of the 9 pieces is cut into 3 pieces, resulting in 9 x 3 = 27 pieces.

After the final division, there are 27 pieces of pizza. Therefore, Lupita has enough pieces for the party as the required number of pieces is also 27.

Step-by-step explanation:

Given : Jennifer is on a hiking trip. She begins her hike at an altitude of 4,000 feet, and she is descending with an average speed of 40 feet per minute.

We have to Graph the function that represents the given situation.

Let the y - axis represents the height of Jennifer (in feet) and x axis represents the time (in minutes)

Since initially, Jennifer is at 4000 feet.

and is descending with an average speed of 40 feet per minute.

So when she begins to descend she is at 4000 feet that is y- intercept is 4000.

Then, the equation of graph is given by

y = -40x + 4000

As she is descending at the rate of 40 feet per minute so  -40x

Thus, The graph for the given equation can be drawn as shown below.

also, when x = 100

then y = -40(100) - 4000 = 0

Plot points (0, 4000) , (100,0) to obtain the graph.

When 250 is divided by 10 the 2nd power will be 5².

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

250 is divided by 10. Then the value of the expression will be

⇒ 250 / 10

⇒ 25

Write the expression in the form of 2nd power, then we have

⇒ 25

⇒ 5 x 5

⇒ 5²

When 250 is divided by 10 the 2nd power will be 5².

Answer:

I can ride 3.3 miles in $10.

Step-by-step explanation:

Let i can ride x miles in $10.

So for first 0.5 miles I have paid = $2.4

The for remaining ride of (x - 0.5) payment done = $[tex]\frac{0.20}{0.1}\times (x-0.5)=2(x - 0.5)[/tex]

I gave the tip = $2

Total payment I have done for the ride = $10

So equation will be

2.4 + 2(x - 0.5) + 2 = 10

4.4 + 2x - 1 = 10

3.4 + 2x = 10

2x = 10 - 3.4

2x = 6.6

x = [tex]\frac{6.6}{2}=3.3[/tex]

Therefore, i can ride 3.3 miles in $10.

Altitude not a point of concurrency in a triangle.

The circumcenter of a triangle is the point at which its three perpendicular bisectors coincide. It is the center of the circle that is equidistant from all three of the triangle's vertices and is circumscribed around the triangle.

As, we know

Any location where three or more lines converge is known as a point of concurrency. The centroids, orthocenters, circumcenters, and incenters are the four points of concurrency that are shared. The intersection of a triangle's three medians is known as the centroid.

So, according to that Altitude not a point of concurrency in a triangle.

The solution to the equation 62 = 5 + x is x = 57. This is found by subtracting 5 from both sides of the equation and checking the solution by substitution.

To solve the equation 62 = 5 + x, we will follow algebraic properties to isolate the variable x.

Therefore, the solution to the equation is x = 57, and after checking, it is reasonable.

m=4g+5 is the equation for money will Walter owe if he buys g gallons of gas

An expression is combination of variables, numbers and operators.

Given that Walter pays $4 for each gallon, g, of gas for his lawn mower.

Walter uses a gift card worth $5 to reduce the amount he owes for his purchase.

We need to find the money, m, will Walter owe if he buys 4 gallons of gas.

m=4g+5

Now for 4 gallons we have to find the money.

m=16+5

m=21

Now for gallon =2

m=13

Now for gallon =3

m=17

Hence, m=4g+5 is the equation for money will Walter owe if he buys g gallons of gas

The correct answer is (A) -2y - 2 for x in 3x - 2y = 10.

x + 2 = -2y

3x - 2y = 10

In order to find the second variable, we must take either x or y out of one of the equations. We can specifically exclude x by substituting the following in the expression:

From the first equation into the second, x = -2y - 2. With this change, x will no longer be present in the second equation, allowing us to determine the value of y. As a result, we must replace the phrase with:

For x in the equation, -2y - 2:

3x - 2y = 10

To acquire:

3(-2y - 2) - 2y = 10

To put it simply: -6y - 6y - 2y = 10

combining comparable phrases

-8y = 16

y = -2 after dividing both sides by -8.

Once y has been determined, we can add this result back into one of the original equations.

Therefore, the correct answer is (A) -2y - 2 for x in 3x - 2y = 10.

To create a scale diagram, determine the ratio between the length and width of the scale drawing and the actual object.

To create a scale diagram, we need to determine the ratio between the length and width of the scale drawing and the actual object.

In this case, the length of the scale drawing is 8 inches and the actual length of the mp3 player is 4 centimeters.

So the length ratio is 8 inches / 4 centimeters = 2 inches / centimeter.

Similarly, the width ratio can be calculated as 14 inches / 7 centimeters = 2 inches / centimeter.

In Renee's scale drawing of the mp3 player, every 1 cm of the actual mp3 player is represented by 5 cm in the scale drawing. This is calculated by comparing the actual length to the length on the drawing, converting the units to centimeters first. The scale should be consistent for both length and width.

The question describes a situation where Renee is making a scale diagram of her mp3 player. In this case, there is a comparison between the actual size of the mp3 player and it's representation on the scale drawing. Let's use the lengths as a basis for the scale.

The length of the actual mp3 player is 4 cm and the length on the scale is 8 inches. But, to make our comparison valid, we need to make sure that both measurements are in the same unit. Now, since 1 inch is approximately 2.54 cm, our 8 inches become 8 × 2.54 = 20.32 cm.

This means Renee's scale is roughly 5 to 1 (since 20.32 divided by 4 is about 5). Therefore, every 1 cm of the actual mp3 player is represented by 5 cm in the scale drawing.

We can follow the same process for the width and verify that the scale is consistent, which it should be, but in this case, it's not necessary because we've been given that the lengths and the widths have exactly the same proportions in both the drawing and the real object.
