8x – 10 = 3x – 10 + 7x

stira [4]

Answer:

x= 0

Step-by-step explanation:

Let's first simplify the equation to make the PEMDAS process easier.

8x-10=3x-10+7x

8x-10=10x-10

Now lets start the subtracting and dividing process.

8x=10x

0=2x

0=x

Solve the system of equations by finding the reduced row-echelon form of the augmented matrix for the system of equations.

ycow [4]

This involves quite a lot of arithmetic to do manually.

The first thing you do is to make the first number in row 2 = to 0.

This is done by R2 = -3/2 R1 + R2

so the matrix becomes

( 2 1 1) ( -3 )

( 0 -13/2 3/2) (1/2 )

(5 -1 2) (-2)

Next step is to make the 5 in row 5 = 0

then the -1 must become zero

You aim for the form

( 1 0 0) (x)

(0 1 0) (y)

(0 0 1) ( z)

x , y and z will be the required solutions.

I need help with geometry:

nikklg [1K]

Answer:

x = 5

Step-by-step explanation:

6/18 = x/(20-x)

1/3 = x/(20-x) Multiply both sides by 20-x

(20-x)/3 = x Multiply both sides by 3

20-x = 3x Add x in both sides

20 = 4x Divide both sides by 4

5 = x

Given the diagram below, what is the length of segment EF

bekas [8.4K]

Let x = length of segment EF.

Assume that
(a) line segments AD, EF, and BC are parallel, and
(b) the vertical distance between AD and EF is equal to the vertical distance between EF and BC.

Then from similarity between geometric shapes, we can write
$\frac{2.2}{x} = \frac{x}{4.8}$
$x^{2} =(2.2)(4.8)=10.56$
x=3.2 (nearest tenth)

Answer: B. 3.2
