3(x-2)=18 can somebody plzz help me

Answers

Answer:

x=8

Step-by-step explanation:

3(x-2)=18

3x-6=18

3x=18+6

3x=24

x=24/3

x=8

Given : Simplify 3(x - 2) = 18

Solution : According to the question, here we are given an equation i.e 3(x - 2) = 18 where we need to get the value of x by simplifying it.

3(x - 2) = 18

Cross multiplying 3 to the other side

x - 2 = 18/3

x - 2 = 6

Transposing -2 to the right hand side of the equation to get +2

x = 6 + 2

Adding them we get the final answer

x = 8

Henceforth, the required answer is 8

Calculate the slope of the line for Graph B.

Answers

Answer:

-1

Step-by-step explanation:

rise = -2

run = 2

Slope = rise / run

= -2/2 = -1

Since also the angle made by the line and x axis in anti clockwise direction is > 90° the slope will be-ve .

Answer:

Slope = -1

Step-by-step explanation:

You are provided with two points on the line (-5, 7) and (1,1).

[tex]Slope = \frac{y_{2} -y_{1}}{x_{2} -x_{1}}[/tex]

[tex]Slope = \frac{7-1}{-5-1} =\frac{6}{-6} =-1[/tex]

If the perimeter of a square is 7 feet how many inches long is the square on each side?

Answers

Answer:

7÷4=1.75

Step-by-step explanation:

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

The length of each side of the square is 1.75 feet.

What is square?

"It is a quadrilateral with all sides are equal and all angles are 90°"

What is the perimeter of square?

"The perimeter of square is, P = 4 × a,

where 'a' is the side length of the square."

For given example,

the perimeter of a square is 7 feet.

⇒ P = 7 feet

Let 'a' be the length of each side of the square.

Using the formula of perimeter of a square,

⇒ P = 4 × a

⇒ 7 = 4 × a

⇒ a = 7 ÷ 4

a = 1.75 feet

Therefore, the length of each side of the square is 1.75 feet.
