En la figura anterior, las rectas M y N son paralelas. ¿Cuántos grados mide el ángulo BAC ?

Square has a side length of (x-5). If the perimeter is 24, what is the value of x? *

san4es73 [151]

Answer:

11 units

Step-by-step explanation:

hey there,

< A square has 4 sides that are all always equal to each other. The perimeter is all the sides summed up together. That means (for example), if one side of the square is 2 cm, then we know that the perimeter is 8 cm, because 2 + 2 + 2 + 2 = 8 (or 2×4=8).

Here we are given that one side is equal to "x-5". Pretend that is a number and solve as I did just right above:

(x-5)×4 = 4x -20

Now we know that the perimeter is (4x-20) units (when you don't know what the units are then just put "units").

We also know that the perimeter can be a number which is 24. That means these two values are equal to each other.

4x-20 = 24

Now solve! Bring x to one side, and all the numbers to the other side.

4x = 44

x = 11

We now know that the value of one side of the square (x) is equal to 11 units. >

Hope this helped! Feel free to ask anything else.

What is A slope? explain:

tatyana61 [14]

Answer:

Slope is the steepness of a line as it moves from LEFT to RIGHT. Slope is the ratio of the rise, the vertical change, to the run, the horizontal change of a line. The slope of a line is always constant (it never changes) no matter what 2 points on the line you choose.

Solve the systems of equation by graphing (Picture provided)

11Alexandr11 [23.1K]

Answer:

Option b

Step-by-step explanation:

The following system of linear equations is shown

$x + y = 8\\2x + y = 3$

These are two different slope lines.

We find the cut points of both lines with the axes.

$x + y = 8$

Cut with the x axis. (y = 0)

$x = 8$

Cut with the y axis. (x = 0)

$y = 8$

...................................................................

$2x + y = 3$

Cut with the x axis. (y = 0)

$2x = 3\\x = 1.5$

Cut with the y axis. (x = 0)

$y = 3$

The solution to this system will be a point for which it is fulfilled that:

$x + y - 8 = 2x + y-3$

In the image, different graphs with intersections are shown.

Locate among the options, one that shows the two lines of the system of equations according to their intersections with the x and y axes.

Option b is the only one that shows the graph of the lines

$x + y = 8\\2x + y = 3$

Then, The point of intersection of both lines in the graph is:

(-5, 13)

Therefore the solution of the system of equations is: (-5, 13)

You can verify this by replacing the point in the relationship

$x + y - 8 = 2x + y-3\\\\(-5) +13 -8 = 2 (-5) +13 -3\\\\0 = 0$

Equality is satisfied

Finally the answer is the option b

Alice has 1/5 as many miniature cars as Sylvester has. Sylvester has 35 miniature cars. How many miniature cars does Alice have?

Volgvan

multiply 35 by 1/5, which is the same as dividing 35 by 5

35 /5 = 7

Alice has 7 cars
