Consider this system of equations.
p = 2n
p - 5 = 1.5n
What value of n makes the system of equations true.
Explain how you got your answer.

Answers

Answer 1

Answer: n=10

Step-by-step explanation:

p=2n

p-5=1.5n

- replace 2n in the 2nd equation for p

2n-5=1.5n

2n=1.5n=5

2n-1.5n=5

0.5n=5

n=10

Answers

Answer:

Option (d) is correct.

Slope of given line y = 5x -4 is 5

Step-by-step explanation:

Given equation of line as y = 5x - 4

We have to find the slope of given line.

For the general equation of line y = mx + c , where m is the slope of line and c is the y- intercept.

Slope of line is given by derivative the equation of line with respect to x, that is

Consider the given equation y = 5x - 4

then slope is

Thus, slope of liven line is 5 .

Also, by comparing the given equation with general equation the slope of line is 5 .

Thus, option (d) is correct.

Answer:

x = -40

Step-by-step explanation:

Rewrite "(x - 4)/4" in a different way:

⇒ 8 + x/2 = (x - 4)/4 - 1

⇒ 8 + x/2 = x/4 - 4/4 - 1

Simplify the R.H.S:

⇒ 8 + x/2 = x/4 - 1 - 1

⇒ 8 + x/2 = x/4 - 2

Add 2 both sides and subtract x/2 both sides:

⇒ 8 + x/2 = x/4 - 2

⇒ 8 + 2 = x/4 - x/2

⇒ 10 = x/4 - 2x/4

Simplify the R.H.S:

⇒ 10 = x/4 - 2x/4

⇒ 10 = -x/4

⇒ 10 × 4 = -x

Answer:

  (a) 136 ft

  (b) $680

Step-by-step explanation:

You want to know the perimeter length and the cost of tiling around a pool with the L-shape shown.

(a) Perimeter

The sum of horizontal lengths at the bottom of the pool outline is the same as the length at the top.

The sum of vertical lengths at the left of the pool outline is the same as the length on the right.

The perimeter is the sum of horizontal and vertical lengths of the outline, so is ...

  P = 2(40 ft + 28 ft) = 136 ft

The perimeter of the pool is 136 ft.

(b) Tile cost

The cost of tile is found by multiplying the cost per length by the length around the pool.

  tile cost = ($15/(3 ft))(136 ft) = $680

It will cost $680 to put tiles around the edge of the pool.

What is the box plot

To create a box plot for the given data set:

25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, and 24

One first need to look for some key statistics that will help one make  the plot and they are

Minimum value in the data set.First quartile (Q1)Median (Q2)Third quartile (Q3)Maximum value in the data set.

So first sort the data in ascending order:

18, 19, 20, 21, 24, 25, 26, 27, 30, 31, 32, 33, 36, 36, 38

Minimum: 18 First quartile (Q1): 21.Median (Q2):  27.Third quartile (Q3):  33.Maximum: 38.

The lines coming out from the box (whiskers) show the smallest and largest values that are within a certain range around the middle of the data. Any data points that are different from the others and fall outside a certain range are called outliers. These outliers are shown separately on a graph.

The box plot shows us how the data is spread out and gives us information about the average value and any very high or very low values.

For what value of k will the following linear system have infinitely many solutions?

Answers

There are infinitely many solutions to a linear equation with the same variable term on both sides of the equation.

We have to find the coefficient of "b"

from first equation:

2a + b = -6b = -6 - 2a

from second equation:

6a + kb = -18b = (-18 - 6a)/k

solve them simultaneously:

(-18 - 6a)/k = -6 - 2a(-18 - 6a)/(-6 - 2a) = kk = 3

How long, in feet, will the table be when the carpenter builds it?

Answers

Using proportions, it is found that the table will be 110 feet long when the carpenter builds it.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In the drawing, 0.75 inches represent 11 feet. The drawing is of 7.5 inches, and the real dimension is of d, hence the rule of three is given by:

0.75 inches - 11 feet.

7.5 inches - d feet

Applying cross multiplication:

0.75d = 7.5 x 11

d = 7.5 x 11/0.75

d = 110.

The table will be 110 feet long when the carpenter builds it.

More can be learned about proportions at https://brainly.com/question/24372153

The scale model of the table would ensure that the actual table is bigger than the scale model

The length of the table would be 110 feet

How to determine the table length?

The scale model is given as:

Ratio = Scale : Actual

So, we have:

Ratio = 3/4 inches : 11 feet

For a table of 7 1/2 inches, we have the following ratio

Ratio = 7 1/2 inches : Actual

Equate both ratios

7 1/2 inches : Actual = 3/4 inches : 11 feet

Express as decimals

7.5 inches : Actual = 0.75 inches : 11 feet

Rewrite as:

7.5 : Actual = 0.75 : 11 feet

Express as fraction

Actual/7.5 = 11 feet/0.75

Multiply both sides by 7.5

Actual = 7.5 *  11 feet/0.75

So, we have:

Actual = 110 feet

Hence, the length of the table would be 110 feet
