hii, does anyone know a example for 28 + 29? thanks

Answer:

x = 7

Step-by-step explanation:

Given

3(2x - 9) = 15 ( divide both sides by 3 )

2x - 9 = 5 ( add 9 to both sides )

2x = 14 ( divide both sides by 2 )

x = 7

Answer: a = -3

Step-by-step explanation: First we distribute the -2 to a and -3 to get -2a+6=12, then subtract 6 on both sides, -2a=6, finally divide by -2 on each side to get a = -3.

Hope this helps!

Please consider marking BRAINLIEST!

subtract 123.95 from both sides

45w = -630

divide both sides by 45

w = -14

Answer:

The most accurate statement is that the actual measure of the line segment is between 5.5 cm and 6.49 cm

Step-by-step explanation:

Here, given the measurement of the line segment rounded to the nearest cm as 6 cm, we want to give the most accurate statement about the actual measure

What we need here is the set of numbers which can be rounded to 6 cm

From 5.5 cm to 6.49 cm , all the measurements here can be rounded up to 6 cm

So the most accurate statement will be that the actual measure of the line segment is between 5.5 cm and 6.49 cm

The most accurate statement about the actual measure of the line segment be is between 5.56 to 6.49.

The measurement of the line segment rounded to the nearest cm as 6 cm, we need to give the most accurate statement.

A line segment is a part of a line that connects two points which are distinct endpoints and contain every point on it.

From 5.56 cm to 6.49 cm, all the measurements here can be rounded up to 6 cm.

So, the most accurate statement will be the actual measure of the line segment between 5.56 cm and 6.49 cm.

Answer:

Step-by-step explanation:

Let the area of the rectangle be Length × width

LW = 8000

If the diagonal is 10feer greater than one of its length then:

D = 10+L

Diagonal is represented using the Pythagoras theorem as shown:

D² = L²+W²

(10+L)²= L²+W²

100+20L +L² = L²+W²

From LW = 8000

W = 8000/L

100 + 20L = (8000/L)²

100 +20L = 64,000,000/L²

Cross multiply

100L² + 20L³ = 64,000,000

2L³+10L² = 6,400,000

L³+5L² = 3200000

L³+5L² -3200000 = 0

Answer:

55 ft by 146 ft

Step-by-step explanation:

Given the following :

Area of rectangle = 8000 ft^2

Area of rectangle = length(L) * width(W)

Let length of a side = x

Length of side 2 = 8000 / x

Diagonal = 10 feet longer than one side = (x + 10)

The diagonal is the hypotenus = (x + 10)²:

Hyp² = (8000/x)² + x²

(x + 10)² = (8000/x)² + x²

x² + 20x + 100 = 64,000,000 / x² + x²

20x + 100 = 64,000,000 / x²

(20x + 100) * x² = 64,000,000

20x³ + 100x² - 64,000,000 = 0

x³ + 5x² - 3200000 = 0

Using calculator

x = 145. 71 = 146 ft

8000 / x

8000/145.71

= 54.9 ft

= 55ft

55ft by 146 ft

=======================================================

Explanation:

Start by graphing the system of equations

[tex]\begin{cases}x-y = 6\\2x+5y = -4\\ x = -1\end{cases}[/tex]

This is represented as the boundary lines. The first two equations produce solid boundary lines. The last equation makes a dashed boundary line. We use solid boundary lines whenever "or equal to" is involved with the inequality sign.

Note how 7 separate regions result from the intersecting lines. Check out the diagram below to see the different regions.

--------------------------

To graph [tex]x-y \le 6[/tex] which is the same as [tex]y \ge x-6[/tex], we will shade in regions 1, 2, 4 and 5. All of these regions are above the boundary line y = x-6

Ignore any other region (3,6, and 7) since they don't make the first inequality true.

Of regions 1, 4, 5 and 6, only regions 4 and 5 are below the boundary line 2x+5y = -4. So we cross off regions 1 and 6.

We're now down to just two regions: 4 and 5

We cross off region 5 because it is not to the right of the vertical line x = -1

All that's left is region 4. Any point in region 4 makes all of the three original inequalities true.

So the solution will only have region 4 shaded like choice D shows.
