-10n + 3(8+8n)=-6(n-4)

Answers

Answer 1

Answer: First we have to multiply factor by every argument from the parenthesis.
-10n+3(8+8n)=-6(n-4)
-10n+3*8+3*8n=-6n+6*4
-10n+24+24n=-6n+24
24+14n=-6n+24 /-24
14n=-6n /+6n
20n=0 /:20
n=0 - its the answer

Solve for x 3x+2=2x-7

Answers

Answer:

x = - 9

Step-by-step explanation:

Given

3x + 2 = 2x - 7 ( subtract 2x from both sides )

x + 2 = - 7 ( subtract 2 from both sides )

x = - 9

X= -9 is the answer

Subtracting 3xy2 from 8xy2 gives the same result as the expression. A. 3xy^2 - 8xy^2 B. -7xy^2 - 2xy^2 C. 7xy^2 - 2xy^2

Answers

Answer:

Option (c) is correct.

$7xy^2-2xy^2$ is the correct expression

Step-by-step explanation:

Given : Expression $3xy^2$ and $8xy^2$

We have to subtract $3xy^2$ from $8xy^2$ and choose the correct expression from the given options.

Consider the given expressions $3xy^2$ and $8xy^2$

we have to subtract $3xy^2$ from $8xy^2$

Thus, while subtracting we write term after 'from' before.

Therefore, $8xy^2-3xy^2=5xy^2$ is the correct expression

Also subtracting $7xy^2-2xy^2=5xy^2$ gives same result.

So, option (c) gives the same result as obtained from given expression.

Subtracting 3xy² from 8xy² is 8xy² - 3xy² = 5xy²

Answer: C. 7xy² - 2xy² = 5xy²

What is Coordinate Geometry?

A coordinate geometry is a branch of geometry where the position of the points on the plane is defined with the help of an ordered pair of numbers also known as coordinates.

The line segment BD is parallel to segment XY

We have to find the value of y

The angle 67 degrees and y are opposite to each other.

So the value of y is 67 degrees

The opposite angles are equal

The value of Y is 67 as angels that are opposite to each other are equal so the angle below Y is 67.

Knowing that we can say that Y is 67 as angels parallel to each other are also equal.

Hence, the value of y is 67 degrees when linesegment BD is parallel to XY.
