Answer:

The answer is going to be 7 or X=7. Here is how that conclusion came to be. Five less than twice a number is 9; here is the mathematical sentence we created to represent the statement:

2X-5=9 now lets work it.

2X-5+5=9+5

2X=14 , lets divide boyh sides of the equation by 2.

2X/2=14/2

X=7 Now lets prove this number represents X.

2(7)-5=9

14–5=9

9=9

Answer:

x = 3.6

Step-by-step explanation:

=> x2 - 12x + 32 = (x - 8)

=> 2x - 12x + 32 = (x - 8)

=> 2x - 12x + 32 = x - 8

=> 2x - 12x - x = -8 -32

=> -10x - x= -40

=> -11x = -40

=> (-11x)/-11 = (-40)/-11

=> x = 3.636363636363636

=> x = 3.6

Answer:

This tile is a sqaure

so , The perimeter of the sqaure is 4× side

so 4 × 3 = 12 in.

therefore , 12 in. is the perimeter of this tile

Answer:

12 inches

Explanation:

You have to add up all of the sides that are parallel to each other. So, 3+3+3+3=12, or 3x4=12, 4= the number of sides in a square.

The solution is 14.38

The value of x from the equation 32 (x − 8) = 14x + 3 is x = ( 14 7/18 )

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

32 (x − 8) = 14x + 3   be equation (1)

Now , on simplifying the equation , we get

32 ( x ) - 32 ( 8 ) = 14x + 3

32x - 256 = 14x + 3

Adding 256 on both sides of the equation , we get

32x = 14x + 259

Subtracting 14x on both sides of the equation , we get

18x = 259

Divide by 18 on both sides of the equation , we get

x = 259/18

The value of x = 14.38

Therefore , the value of x = 14.38 or 14 7/18

Hence , The value of x from the equation is x = ( 14 7/18 )

Answer:

286

Step-by-step explanation:

Formula 2 x (height x depth + height x width + depth x width)
2 x (5 x 7 + 5 x 9 + 7 x 7) = 286

Considering the amounts in each table, the difference function is given as follows:

x|          1       2     3         4

(f - g)(x)|1.74 7.41  17.21   31.34

At each value of x, the difference function (f - g)(x) is given by f(x) - g(x).

Hence, from the table given:

(f - g)(1) = f(1) - g(1) = 1,576.74 - 1,575 = 1.74.

(f - g)(2) = f(2) - g(2) = 1,657.41 - 1,650 = 7.41.

(f - g)(3) = f(3) - g(3) = 1,742.21 - 1,725 = 17.21.

(f - g)(4) = f(4) - g(4) = 1,831.34 - 1,800 = 31.34.

Answer:

3,-2

Step-by-step explanation:

The answer is 3,-2 because left is negative so you would subtract 2 and down is negative so you would subtract 3.

1 inch equals 250 feet.

Multiply the inches on the map by 250 to get total feet.

30 x 250 = 7,500 feet

24 x 250 = 6,000 feet

The park is 7,500 feet long by 6,000 feet wide

The scale factor of the drawing is 1 inch equal to 250 feet. Then the actual length and width are 7500 feet and 600 feet.

The scale factor means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.

A scale drawing of a park is 30 inches long and 24 inches wide. On the drawing, 1 inch is equal to 250 feet. Then the actual dimension will be

Length = 30 × 250

Length = 7500 ft

Width = 24 × 250

Width = 6000 ft

Answer:

Approximately 494,314 people

This is an exponential growth question, specifically population growth. We will use the following equation to help us solve this situation:

P(t) = a(1+r)t

P(t) = total population (??)

a = initial population = 260,000

r = growth factor (the percent as a decimal) = 0.055

1 + r = 1 + 0.055 = 1.055

t = time in years = 12

So, we can substitute all our information and solve:

P(12) = 260,000(1.055)12 = 494,313.95

Rounding to the nearest whole person, 494,314 people in 12 years.

Answer:

1 with 9 2 with 7 3 with 1 4 with 3 and 5 with 5

Answer:

Equation 1 matches with number 9.

Equation 2 matches with number 7.

Equation 3 matches with number 1.

Equation 4 matches with number 3.

Equation 5 matches with number 5.

Step-by-step explanation:

Equation 1:  −9x > −9

−9x > −9

Divide both sides by −9.

-9x/-9 = -9/-9

Since −9 is negative, the inequality direction is changed.

x < 1

x < 1 matches with the graphed solution of number 9.

So, Equation 1 matches with number 9.

Equation 2: 2x + 6≥ −2

2x + 6≥ −2

Step 1: Subtract 6 from both sides

2x + 6 − 6 ≥ −2 − 6

2x ≥ −8

Step 2: Divide both sides by 2

2x/2 ≥ −8/2

Step 3: Simplify

x  ≥  -4

x  ≥  -4 matches with the graphed solution of number 7.

So, Equation 2 matches with number 7.

Equation 3: x − 9 < −5

x − 9 < −5

Step 1: Add 9 to both sides.

x − 9 + 9 < −5 + 9

x < 4

x < 4 matches with the graphed solution of number 1.

So, Equation 3 matches with number 1.

Equation 4: −6x < −12

−6x < −12

Divide both sides by -6

-6x/-6 < -12/-6

Since −6 is negative, the inequality direction is changed

x > 2

x > 2 matches with the graphed solution of number 3.

So, Equation 4 matches with number 3.

Equation 5: -7x + 20 > 55

Step 1: Subtract 20 from both sides.

−7x + 20 − 20 > 55 − 20

Step 2: Simplify

−7x > 35

Step 3: Divide both sides by -7.

-7x/-7 > 35/-7

Step 4: Simplify

x < -5

Since −7 is negative, the inequality direction is changed

x < -5 matches with the graphed solution of number 5.

So, Equation 5 matches with number 5.
