x, y, and z.

Answer:

1/8

Step-by-step explanation:

Answer:

49

Step-by-step explanation:

First, multiply 5 on both sides:

2n = 50

Then, we divide 2 on both sides:

n = 25

Now we got the value of n, let's calculate 2n - 1.

First, multiply 2 by n so we can get 2n:

2 * 25 = 50

Then, we calculate 50 - 1:

We got 49, and that's the answer ^^

Hope this helps!

The value of 2n-1 is 49 if 2n/5=10, after applying the concept of a linear equation and the value of n is 25.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

2n/5 = 10

2n = 50

n = 25

Plug the value of n in the expression 2n - 1

= 2(25) - 1

= 49

Thus, the value of 2n-1 is 49.

Answer:

q = 12/13

Step-by-step explanation:

Step 1: Write equation

1 - (13q - 5) = -6

Step 2: Solve for q

Distribute -1: 1 - 13q + 5 = -6

Combine like terms: 6 - 13q = -6

Subtract 6 on both sides: -13q = -12

Divide both sides by -13: q = 12/13

Answer:

$1.5

Step-by-step explanation:

if each dozen cost $18, we need to divide.......18/12........because 12 is a dozen.

18/12 = 1.5

Yes, 12 can be a part of more than one fact family because the fact family 3*4 or 6*2 or 9+3.

Answer:

D

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

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

with (x₁, y₁ ) = (- 4, 29) and (x₂, y₂ ) = (0, 28) ← 2 ordered pairs from the table

m = [tex]\frac{28-29}{0+4}[/tex] = - [tex]\frac{1}{4}[/tex]

The line crosses the y- axis at (0, 28 ) ⇒ c = 28

y = - [tex]\frac{1}{4}[/tex] x + 28 ← equation of line → D

Answer:

-5x - 32

Step-by-step explanation:

Use distributive rule :   a(b + c) = ab + ac

3x - 8(x + 4) =3x + x*(-8) + 4*(-8)

                   = 3x - 8x - 32         {combine like terms}

                    = -5x - 32

Answer:

700

Step-by-step explanation:4623=4600

i believe this answer is correct

The equivalent fractions for 2/3 are 6/9, 10/15, and 12/18 because multiplicative identity is a feature of multiplication that is used to determine equivalent fractions.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

2/3 by multiplying by 3/3, 5/5, and 6/6.

= (2/3)(3/3)

= 6/9

= (2/3)(5/5)

= 10/15

= (2/3)(6/6)

= 12/18

The multiplicative identity is a feature of multiplication that is used to determine equivalent fractions.

The numerator and denominator of a fraction are multiplied by the same number for determining equivalent fractions.

Thus, the equivalent fractions for 2/3 are 6/9, 10/15, and 12/18 because multiplicative identity is a feature of multiplication that is used to determine equivalent fractions.

Step-by-step explanation:I divided 80.0 by 16.0

Given :

The Dobson exit is halfway between the Mt. Airy exit and the Elkin exit. If the Elkin exit is located at (-5,-2) and the Dobson exit is located at (-1,4).

To Find :

How far is it from the Elkin exit to the Mt. Airy exit.

Solution :

E(-5,-2) , D(-1 ,4 ) .

It is also given that Dobson exit is halfway between the Mt. Airy exit and the Elkin exit.

Let , location of Elkin exit is A(h,k) .

So , point D in terms of A and E is given by :

[tex](\dfrac{h-5}{2},\dfrac{k-2}{2})[/tex] .

Comparing it with given D :

[tex]\dfrac{h-5}{2}=-1\\\\h=3[/tex] [tex]\dfrac{k-2}{2}=4\\\\k=10[/tex]

Therefore , the location of Mt. Airy exit is ( 3, 10 ) .

Distance between Elkin exit to the Mt. Airy exit.

[tex]D=\sqrt{(5-3)^2+(-2-10)^2}\\\\D=12.17\ units[/tex]

Therefore , distance between Elkin exit to the Mt. Airy exit is 12.17 units .

Hence ,this is the required solution .

Answer:

perimeter = 14

Step-by-step explanation:

perimeter = ∑sides

                = x + (x + 3) + (x + 4)  --------eq.

                = 3x + 7

           3x = 7

            x = 7/3

plugin values into the equation:

perimeter = ⁷/₃ + (⁷/₃ + 3) + (⁷/₃ + 4)

                = 14

therefore, the perimeter of a triangle is 14

Answer:

Change in elevation= 431 feet/mile marker

Step-by-step explanation:

given data

Elevation at mile marker 4 = 6135 feet

Elevation at mile marker9 = 8290 feet

to find out

average change in elevation

solution

we get here average change in feet per mile marker  that is express as

average change in feet per mile = change in elevation ÷ change in mile marker     .....................1

put hree value we get

average change in feet per mile = [tex]\frac{8290-6135}{9-4}[/tex]  

average change in feet per mile = 431 feet/mile marker

so

Change in elevation= 431 feet/mile marker
