Solve for x.
Need help, please

Answers

Given:

The figure of a triangle with mid segment.

To find:

The value of x.

Solution:

According to triangle mid-segment theorem, the mid-segment of a triangle is parallel to the base and the length of the mid-segment is half of the base.

Using the triangle mid-segment theorem, we get

[tex]AB=\dfrac{1}{2}EG[/tex]

[tex]x+14=\dfrac{1}{2}(17+x)[/tex]

[tex]2(x+14)=17+x[/tex]

[tex]2(x)+2(14)=17+x[/tex]

On further simplification, we get

[tex]2x+28=17+x[/tex]

[tex]2x-x=17-28[/tex]

[tex]x=-11[/tex]

Therefore, the value of x is -11.

There are 20 students in the drama club. Next year, 5
students will leave the drama club and some students
will join. If d is the number of students who will join the
drama club, write an expression to represent the total
number of students in the drama club next year.

Answers

Answer:

27

Step-by-step explanation:

Let d = number Of drama club members

let y = number of yearbook club members

now you can write two equations, one for the total number of students, and one for the difference between them.

d + y =64

d - y = 10

 

to solve for d, add these two lines together (so as to remove the y’s)

2d + 0y = 74

d = 37

now substitute back into one of the formulas

d+y=64

37+y=64

subtract 37 from each side,

y = 27

como simplifica essa expressão: x+6y-7z+2-8x-12y-10z-20:​

Answers

Answer:

-17 z - 6 y - 7 x + -18

Step-by-step explanation:

Simplify the following:

x + 6 y - 7 z + 2 - 8 x - 12 y - 10 z - 20

Hint: | Group like terms in x + 6 y - 7 z + 2 - 8 x - 12 y - 10 z - 20.

Grouping like terms, x + 6 y - 7 z + 2 - 8 x - 12 y - 10 z - 20 = (-7 z - 10 z) + (6 y - 12 y) + (x - 8 x) + (2 - 20):

(-7 z - 10 z) + (6 y - 12 y) + (x - 8 x) + (2 - 20)

Hint: | Combine like terms in -7 z - 10 z.

-7 z - 10 z = -17 z:

-17 z + (6 y - 12 y) + (x - 8 x) + (2 - 20)

Hint: | Combine like terms in 6 y - 12 y.

6 y - 12 y = -6 y:

-17 z + -6 y + (x - 8 x) + (2 - 20)

Hint: | Combine like terms in x - 8 x.

x - 8 x = -7 x:

-17 z - 6 y + -7 x + (2 - 20)

Hint: | Evaluate 2 - 20.

2 - 20 = -18:

Answer: -17 z - 6 y - 7 x + -18

A = 120 cm²

Step-by-step explanation:

The area of the trapezoid is given by :

[tex]A=\text{sum of parelllel sides}\times \text{height}[/tex]

Two parallel sides = 7cm and 13 xm

Sum of parallel sides = 7 cm + 13 cm

= 20 cm

Height, h = 6 cm

So,

The area of the trapezoid is :

[tex]A=20\times 6\\\\A=120\ cm^2[/tex]
