Answer:

The linear equation for the total combination age is [tex]X+7+(X+4)+7=24[/tex]

Step-by-step explanation:

If Jane is X years old today. And her brother is 4 years older then her brothers age is,

X+4.

Jane's age after 7 years = X+7

Jane's Brothers age after 7 years = (X+4)+7

So after seven years their combined age will be 24, Lets write this in an equation form,

[tex]X+7+(X+4)+7=24[/tex]

So the linear equation for the total combination age is,

[tex]X+7+(X+4)+7=24[/tex]

Answer:

Step-by-step explanation:

Given that Henry  deposited $420 into a savings account. There is a $5.00 per month service fee on the account. Also, Henry decides he wants to withdraw $25 a week for spending money.

Let us convert everything into days.

30 days a month and 7 days in a week

Service charges for 30 days = 5

withdrawn amount for 7 days = 25

Let x be the total no of days

Then [tex]\frac{25x}{7} +\frac{5x}{30}= 420\\\\750x+35x=420(7)(30)\\785x=420(7)(30)\\x=112.3567[/tex]

The solution of the system of equations and inequalities, indicates that the solution are;

In order to find the solution of the system of equations by graphing, the lines are graphed on the same coordinate plane and the point at which the two graphs intersect is the solution of the system of equations.

1) y = (1/4)·x - 4, y = (-1/2)·x - 1,

The x-coordinates at the point of intersection, can be found by noting that the y-values of both equations are the same

Please find attached the graph of the system of equations with the point of intersection, (4, -3), which corresponds to x = 4, and y = -3, created with MS Excel

The solution of the system of equations therefore is; x = 4, y = -3

2. 3·x - 2·y = 8

x - 2·y = 4

Making y the subject of both equations, we get;

y = (3/2)·x - 4

y = (1/2)·x - 2

The graph of the above two equations can be plotted on the same coordinate plane using MS Excel, is attached

The point of intersection of the two graphs is (1, -2.5)

The solution of the system of equations is therefore; x = 1, and y = -2.5

3) The solution of the system of inequalities is the feasible region, corresponding to the region that satisfies both inequalities;

Please find attached the graph of the inequalities, showing the positive region that satisfies both inequalities, which is the triangle with vertices, (0.51, 0), (1, 1), and (1.5, 0)

4) The inequalities can be graphed by making y the subject of both inequalities and graphing the equations on the same coordinate plane.

x + y > -2, therefore; y > -2 - x

6·x - y ≥ 3, therefore; y ≤ 6·x - 3

6·x - 3 = -2 - x

The points in the feasible region of the graph are; points below and on the line, y = 6·x - 3, above the line y = -2 - x, and to the right of the point (1/7, -2 1/7)

Answer:

2.72 m/s

Step-by-step explanation:

We are given that

Boy jogs=250 meters

Time taken by boy=110 seconds

We have to find the average speed in m/s

In order to find the average speed then we will divide distance by time

[tex]Average\;Speed=\frac{distance}{time}[/tex]

Using the formula then we get

Average speed=[tex]\frac{250}{110}=2.72 m/s[/tex]

Hence, the average speed=2.72 m/s

Final answer:

To calculate the average speed, the boy's distance jogged (250 meters) is divided by the time taken (110 seconds), yielding an average speed of 2.27 m/s.

Explanation:

The student's question asks how to calculate the average speed of a boy who jogs a certain distance in a given amount of time. To find the average speed, you divide the total distance traveled by the total time taken. In this case, the boy jogs 250 meters in 110 seconds.

The calculation for the average speed (v) would be:

Distance (d) = 250 meters

Time (t) = 110 seconds

Average Speed (v) = d / t

Plugging the values into the equation yields:

Average Speed (v) = 250 m / 110 s = 2.27 m/s

Hence, the boy's average speed is 2.27 meters per second.

13, paula has 6, myles has 1 more than her that mean he has 7

6+7= 13

Answer:

13

Step-by-step explanation:

We know that Paula has 6 video games and Myles has one more video game than Paula.

So the number of video games Myles has will be equal to 6 + 1 = 7.

Now that we know the number of games that Paula and Myles have, we can find the number of video games in all by simply adding the two numbers:

Total number of video games = 6 + 7 = 13

Therefore, Paula and Myles together have 13 video games.

Let's have the first number be x, the second number y, and the third number z.

Because the second number is six more than the first, y = x + 6.

Because the third number is twice the first, z = 2x.

The three numbers added together equals 26, so 26 = x + y + z.

Let's substitute y = x + 6 and z = 2x into 26 = x + y + z.  This gives us:

26 = x + x + 6 + 2x

26 = 4x + 6

We subtract 6 from both sides of the equation and divide by 4 to get:

5 = x

Now, we'll put x = 5 into our previous to equations to find y and z:

y = 5 + 6

y = 11

z = 2*5

z = 10

Let's check out answer.  10 + 11 + 5 = 26.  10 is twice of 5 and 11 is 6 more than 5.  Thus our three numbers are 10, 11, and 5.

The three numbers are 5, 11 (5 + 6), and 10 (2 * 5)

Let's call the first number x

The second number is 6 more than the first, so it is x + 6

The third number is twice the first, so it is 2x

The sum of the three numbers is 26, so we have the equation x + (x + 6) + 2x = 26

Combining like terms, we get 4x + 6 = 26

Subtracting 6 from both sides, we get 4x = 20

Dividing both sides by 4, we get x = 5

So the three numbers are 5, 11 (5 + 6), and 10 (2 * 5)

"The correct answer is that diagrams showing how matter moves through organisms and the environment are called cycles because they depict continuous, circular pathways.

In ecosystems, matter is not created or destroyed but is continuously recycled. This recycling process occurs in a loop or cycle, where matter moves from the environment to organisms and then back to the environment. For example, in the carbon cycle, carbon dioxide is taken in by plants during photosynthesis, then passed on to animals that consume the plants, and eventually returned to the environment through processes like respiration and decomposition.

These cycles are essential for the sustainability of ecosystems because they ensure that nutrients and other materials are reused and not depleted. The term ""cycle"" reflects the repeating and ongoing nature of these processes, highlighting the interconnectedness and interdependence of organisms and their environment. By using diagrams to represent these cycles, we can visualize and better understand the complex interactions and pathways that matter follows in ecosystems."

To compare the ratios 2 to 7 and 5:7 using the circles to model we need to make two circles first.

Then we need to make 7 parts of each circle.

For 2:7 ratio, we need to shade 2 parts of the total 7 parts of the circle.

For 5:7 ratio, we need to shade 5 parts of the total 7 parts of the circle.

So, the first circle represents  2:7 ratio and second circle represents  5:7 ratio.

Answer:

[tex]V_{E} = -22.5 / 15 = 1.5 miles/minute\\V_{F} = 7.5 / 15 = 0.5 miles/minute[/tex]

Step-by-step explanation:

To answer this problem, we must bear in mind that the express train travels 3 times faster than the freight train.

If we call F the distance that the freight train travels and we call E at the distance that the express train travels, we must have the distance between them after 15 minutes it must be 30 miles.

So

[tex]F + E = 30\\[/tex]

We also know that:

[tex]E = 3F[/tex]

Since the express train travels 3 times faster than the freight train.

So, like both equations, we have to:

[tex]F + 3F = 30\\F = 30/4\\F = 7.5 miles\\[/tex]

Then [tex]E = 7.5*3 = 22.5[/tex] miles in the opposite direction.

This is the distance you traveled in 15 minutes.

Therefore, the speed of the express train ([tex]V_{E}[/tex]) is the distance traveled between the time it did

[tex]V_{E} = -22.5 / 15 = 1.5 miles/minute\\V_{F} = 7.5 / 15 = 0.5 miles/minute[/tex]

Final answer:

Ally's box has a total surface area of 594 square centimeters, calculated using the surface area formula for a rectangular prism: Surface Area = 2lw + 2lh + 2wh.

Explanation:

The surface area of a box can be calculated by finding the area of all six faces and adding them together. Since the box Ally is designing has dimensions of 12 cm long, 9 cm high, and 9 cm deep, we will have two faces for each dimension. To calculate the surface area of Ally's box, we use the formula:

Surface Area = 2lw + 2lh + 2wh

Where l is the length, w is the width, and h is the height of the box. Now, plugging in Ally's box dimensions:

Surface Area = 2(12 cm)(9 cm) + 2(12 cm)(9 cm) + 2(9 cm)(9 cm)

Surface Area = 2(108 cm2) + 2(108 cm2) + 2(81 cm2)

Surface Area = 216 cm2 + 216 cm2 + 162 cm2

Surface Area = 594 cm2

Therefore, the total surface area of Ally's box is 594 square centimeters.
