Answer:

x=7

Step-by-step explanation:

The diagram shows us that the two lines at the base of the triangle are congruent. It also shows us that this line's perpendicular bisector passes through the third vertice of the triangle. When we see triangles in this form, it tells us that it is an isosceles triangle. Isosceles triangles have two congruent side lengths with their base having a different side length.

Using this information, we can tell that the side lengths that are congruent are the ones involving x with the base of the triangle having a side length of 46 units (23+23=46). Therefore, this means that the following equation is true:

6x+18=3x+39

Now, we can solve for x.

6x+18=3x+39

Subtract both sides by 18

6x+18-18=3x+39-18

6x=3x+21

Subtract both sides by 3x

6x-3x=3x+21-3x

3x=21

Divide both sides by 3

3x/3=21/3

x=7

I hope this helps!

5. Se hizo una encuesta a estudiantes, de una carrera de un total de 6000 estudiantes encuestados el 75% le gusta leer. ¿Cuántos
Nataly_w [17]

La encuesta indica que de entre todos los estudiantes de una carrera, 4500 les gusta leer.

<h3 /><h3>Percentage</h3>

The percentage is the given definition for a fraction whose denominator is equal to 100. It is represented by %. See the example: \frac{30}{100} =\frac{3}{10}=0.3*100=30 \%.

The question gives:

  • 6000 students
  • 75% of students like to read

Then, you will have:

6000\cdot \frac{75}{100}\\ \\ 6000\cdot \frac{3}{4}\\ \\ \frac{18000}{4} =4500

Find the perimeter AND area of the parallelogram ABCD. Show all work
nexus9112 [7]

Since, this is parallelogram

so, opposite sides are equal

We will find value of sides

Calculation of AB:

we are given point A=(-2,3)

point B=(4,0)

we can use distance formula

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

now, we can plug values

AB=\sqrt{(4+2)^2+(3-0)^2}

AB=3\sqrt{5}

Since, this is parallelogram

so, opposite sides are equal

so,

CD=AB=3\sqrt{5}

Calculation of AD:

point A =(-2,3)

point D=(-5,2)

we can use distance formula

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

now, we can plug values

AD=\sqrt{(-5+2)^2+(2-3)^2}

AD=\sqrt{10}

Since, this is parallelogram

so, opposite sides are equal

so,

BC=AD=\sqrt{10}

Calculation of AE:

point A=(-2,3)

point E=(-3,1)

we can use distance formula

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

now, we can plug values

AE=\sqrt{(-3+2)^2+(1-3)^2}

AE=\sqrt{5}

(a)

we know that

perimeter of a parallelogram is sum of all sides

so,

perimeter is

=AB+BC+CD+DA

now, we can plug values

=3\sqrt{5}+\sqrt{10}+3\sqrt{5}+\sqrt{10}

=6\sqrt{5}+2\sqrt{10}...........Answer

(b)

we can use area of parallelogram formula

A=AE\times CD

we can plug values

A=\sqrt{5}\times 3\sqrt{5}

A=15............Answer

Please help! Need to pass a module test!

-1 - 8 / 2 + 1 = -9 / 3 = -3

-1 = -3(2) + b
-1 = -6 + b
Add 6 to both sides.
5 = b

y = -3x + 5
