What is the value of x?

Answers

Answer:

a value

Step-by-step explanation:

Answer:

Simplifying

4x + -23 = 2x + 17

Reorder the terms:

-23 + 4x = 2x + 17

Reorder the terms:

-23 + 4x = 17 + 2x

Solving

-23 + 4x = 17 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

-23 + 4x + -2x = 17 + 2x + -2x

Combine like terms: 4x + -2x = 2x

-23 + 2x = 17 + 2x + -2x

Combine like terms: 2x + -2x = 0

-23 + 2x = 17 + 0

-23 + 2x = 17

Add '23' to each side of the equation.

-23 + 23 + 2x = 17 + 23

Combine like terms: -23 + 23 = 0

0 + 2x = 17 + 23

2x = 17 + 23

Combine like terms: 17 + 23 = 40

2x = 40

Divide each side by '2'.

x = 20

Simplifying

x = 20

5x = 3.40 × 112

next multiply 3.40 by 112 (simplifying) so you get

5x = 380.8

last you divide 380.8 by 5x getting your answer of $76.16

If a rectangle has the sides 5x-3 and 6x-4 what is the area and perimeter

Answers

Step-by-step explanation:

[tex]A = lw[/tex]

[tex]A=(5x-3)(6x-4)[/tex]

[tex]A=30x^2-20x-18x+12[/tex]

[tex]A=30^2-28x+12[/tex]

[tex]P=2(l + w)[/tex]

[tex]P = 2(5x - 3 + 6x - 4)\\P=2(x-7)\\P=2x-14[/tex]

Answer:

[tex]Perimeter = 22x - 14[/tex]

[tex]Area = 30 {x}^{2} - 38x + 12[/tex]

Step-by-step explanation:

Length of rectangle (l) = 5x - 3

Weidth of rectangle (w) = 6x - 4

Perimeter of the rectangle = [tex]2(l + w)[/tex]

[tex] = > 2(5x - 3 + 6x - 4)[/tex]

[tex] = > 2(11x - 7)[/tex]

[tex] = > 22x - 14[/tex]

Area of the rectangle = [tex]l \times w[/tex]

[tex] = > (5x - 3)(6x - 4)[/tex]

[tex] = > 5x(6x - 4) - 3(6x -4)[/tex]

Which functions are even? Check all of the boxes that apply.
f(x) = x2 – 3x + 2
7x) = -2)
f(x) = |x|

Answers

Answer:

C) f(x) = |x|

Step-by-step explanation:

Determine if Odd, Even, or Neither

f (x) = |x|

Find f (−x) by substituting −x for all occurrence of x in f (x). f(−x) = |−x|

Make −x positive.

f(−x) = |x|

A function is even if f(−x) = f(x).

Check if f(−x) = f(x).

|x| = |x|

Since |x| = |x|, the function is even.

Earl runs 50 meters in 20 seconds. How many meters does Earl run per second?

Answers

Answer:

2.5 meters

Step-by-step explanation:

Answer:

Earl can run 2.5 meters in one second.

Step-by-step explanation:

We know that Earl can run 50 meters in 20 seconds. That means he can run 150 meters in one minute and 9,000 meters (or 9 kilometers) in one hour. 50 meters / 20 seconds = ? meters / 1 second

50 meters / 20 seconds = x / 1 second

(50 x 1) = (20) (x)

50 = 20x divide both sides by 20 to get the "x" alone

50 / 20 = x

2.5 = x

Find the median: In a particular year, approximately 1.7 million people took the mathematics section of a college achievement test. Of these, 44% scored less than 490, 45% scored less than 500, 48% scored less than 510, 51% scored less than 520, and 57% scored less than 530. In what interval is the median score? The median score is in the interval â–¼(Choose one).

Answers

Answer:

the median score would be between 510 and 520

Step-by-step explanation:

The computation of the median score is shown below

In the case of the continuous probability distribution, the median value is the mid value in which the number is equal to fall to above or below it

Here

P(X = median) = 0.5 = 50%

So the median score would be between 510 and 520

Hence, the same is to be considered
