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

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]
[tex] = > 30 {x}^{2} - 20x - 18x + 12[/tex]
[tex] = > 30 {x}^{2} - 38x + 12[/tex]

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

The population of a town is 20.000. It decreases at a rate of 9% per year. In about how many years will the population be fewer than 13,000?
Answers
It will take approximately four years for the population to be fewer than 13,000.
What is the rate?A rate is a type of ratio that compares two values with distinct units. A rate is expressed as a fraction.
The population of the town is 20.000. It decreases at a rate of 9% per year.
The population of the town decreases by 20,000 × 9% = 1,800 people per year.
To determine how many years it takes for the population to fall below 13,000, you can use the formula:
= (20,000 - 13,000) / 1,800
= 3.88 ≈ 4 years
So, it will take approximately 4 years for the population to be fewer than 13,000.
