9x–2(x+8) = 5x–11(2–x)

Find out X

Answers

Answer 1

Answer:

Answer:

x = 6/9

Step-by-step explanation:

9x - 2(x+8) = 5x - 11(2-x)

9x - 2x - 16 = 5x -22 + 11x

collect the like terms

7x - 16 = 5x -22 + 11x

7x-5x = -22 +16 + 11x

2x = -6 + 11x

6 = 11x - 2x

6 = 9x

divide both sides by 9

6/9 = x

What is 2(x-4)+38=4x

Answers

Alright so first I got X=15.
To do this you will need to solve for X.
Step 1: Simplify both sides of the equation.
2(x−4)+38=4x
Simplify: 2x+30=4x
Step 2: Subtract 4x from both sides.
2x+30−4x=4x−4x−2x+30=0
Step 3: Subtract 30 from both sides.
−2x+30−30=0−30−2x=−30
Step 4: Divide both sides by -2.
−2x−2=−30−2x=15
And you get X=15! Hope I helped!

∙•❁We are now going to solve your problem Step-By-Step, here we go!❁•

∙•❁Question:

2(x−4)+38=4x

∙•❁Simplify both sides of the equation:

2(x−4)+38=4x

∙•❁Let's simplify step-by-step:

2(x−4)+38=4x

(2)(x)+(2)(−4)+38=4x(Distribute)

2x+−8+38=4x

(2x)+(−8+38)=4x(Combine Like Terms)

2x+30=4x

∙•❁Subtract 4x from both sides:

2x+30−4x=4x−4x

−2x+30=0

∙•❁Subtract 30 from both sides:

−2x+30−30=0−30

−2x=−30

∙•❁Divide both sides by -2:

−2x/−2=−30/−2

∙•❁Your final answer is:

x=15

A video game store has a 20% sale on all video games. If the game you wanted cost $32.00,what would the discount be?

Answers

Multiply the decimal conversion of 20% by 32 to find the discount. 20% = 0.20, so 0.20*32 = 6.4. Therefore, the discount is $6.40.
Hope that helped.

You would do cross multiplication and your answer should be $6.40

The figure is made up of two identical squares and has a perimeter of 42 inches. What is the area of one square?

Answers

The area of one square is 49 square inches.

What is a square?

A square is a two-dimensional figure and a four-sided polygon which has it's all sides equal in length and the measure of the angles are 90 degrees. The total interior angle is 360 degrees.

For the given situation,

The figure is made up of two identical squares. So it forms a rectangle.

Let width be x then length be 2x.

Perimeter of rectangle = 42 inches

The formula of perimeter of rectangle is

⇒ $P=2(l+w)$
