Answer:

-2/3

Step-by-step explanation:

Answer:

46

Step-by-step explanation:

you take the values of d and e and plug them in so you would get 2(8)+7(6)-12 the you would multiply the values and you would get 16+42-12

then you would add 16+42 and then subtract that answer by 12. 16+42= 58

58-12=46 so the answer would be 46 unless you need the expression which the expression would be 16+42-12

Answer:

[tex] 3x + 12 = 20 [/tex]

[tex] x = 2\frac{2}{3} [/tex]

Step-by-step explanation:

Let x represent the unknown number.

3 times the unknown number is 3*x. = 3x

The sum of 3x and 12 is said to be 20.

This can be represented by the following equation:

[tex] 3x + 12 = 20 [/tex] (sum means addition)

The equation of the statement given in the equation can be expressed as [tex] 3x + 12 = 20 [/tex].

We can equally find the value of the unknown number using the equation, thus:

[tex] 3x + 12 = 20 [/tex]

Subtract 12 from each side of the equation

[tex] 3x + 12 - 12 = 20 - 12 [/tex]

[tex] 3x = 8 [/tex]

Divide both sides by 3

[tex] \frac{3x}{3} = \frac{8}{3} [/tex]

[tex] x = 2\frac{2}{3} [/tex]

Answer:

[tex]\boxed{m} = - \frac{2}{3} [/tex]

Step-by-step explanation:

[tex]in \: other \: to \: get \: the \: slope \: of : \\ 2x+3y= –12 \\ the \: equation \: needs \: to \: be \: in \: the \: form : \\ y = mx + c \\ \\ where \: m \: is \: the \: slope \\ hence : \\ 2x + 3y = - 12 \\ 3y = - 2x - 12 \\ y = - \frac{ 2}{3} x - 4 \\ therefore \: the \: slope \: \boxed{m} = - \frac{2}{3} [/tex]

Answer:

y=-5/3+7

Step-by-step explanation:

Point Slope Formula: y=m(x-x1)+y

y=-5/3(x-3)+2

-5/3x+5+2

y=-5/3x+7 (y=mx+b)

y=-5/3x+7 is  the equation of the line that passes through the point (3, 2) and has a slope of - 5/3​.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

We need to find  the equation of the line that passes through the point (3, 2) and has a slope of - 5/3​

m=-5/3.

We need to find the y intercept passing through (3,2)

2=-5/3(3)+b

2+5=b

7=b

Hence, y=-5/3x+7 is  the equation of the line that passes through the point (3, 2) and has a slope of - 5/3​.

r = 0,288m

Stapsgewijze uitleg:

Volume van de strandballen V = 4 / 3πr³

1 liter = 0,001 cm³

100l = x

x = 100 * 0,001

x = 0,1 m³

Vervangen in de formule en verkrijg de straal

0,1 = 4 / 3πr³

0,3 = 4πr³

r³ = 0,3 / 4 (3,14)

r³ = 0,3 / 12,56

r³ = 0,02388

r = ∛0,02388

r = 0,288m

Vandaar dat de straal van de strandballen 0.288m is

=======================================================

Explanation:

If the diagonals were congruent, then you can use the SSS property to prove a pair of right triangles are congruent. This leads to showing that we have adjacent congruent corresponding angles. Let's call those angles x and y.

Since they are congruent, we know that y = x. Adjacent angles of any parallelogram add to 180, so x+y = 180

By substitution we can solve for x

x+y = 180

x+x = 180

2x = 180

x = 180/2

x = 90

So y = 90 as well.

This line of thinking is used to show that all four angles of this parallelogram are 90 degrees. A rectangle is any quadrilateral in which all four angles are 90 degrees, so that's why this parallelogram is a rectangle.

n = 28

Step-by-step explanation:

Given

[tex]\frac{3}{4}[/tex] n - 18 = [tex]\frac{1}{4}[/tex] n - 4 ( multiply through by 4 to clear the fractions )

3n - 72 = n - 16 ( subtract n from both sides )

2n - 72 = - 16 ( add 72 to both sides )

2n = 56 ( divide both sides by 2 )

n = 28

Answer:

divide 12 by 2

Step-by-step explanation:

According to the order of operations (PEMDAS), you must first solve inside the parenthesis. This means you must now decide whether to solve 12 /2 first or 2 * 6. Because these are division and multiplication, which are equal, you just solve whichever one comes first, or is on the left. That would by 12/2.

Step-by-step explanation:

The area of corral build for a horse is equal to 4000 feet².

What is the area of a rectangle ?

Area of rectangle is the region occupied by a rectangle within its four sides or boundaries.

It is given that a rancher uses 280 feet of fencing to build a rectangular corral for a horse. This meant the perimeter of corral is equal to 280 feet.

Let's assume that the width of corral is of x feet.

Length of corral = 2.5x

We know that the perimeter of a rectangle is given by :

P = 2 ( L + B )

or

280 = 2 ( 2.5x + x)

Solving for the value of x i.e., width of corral will be :

3.5x = 140

x = width = 40 feet

and

Length = 100 feet

So , the area of corral will be :

A = L × B

or

A = 40 × 100

A = 4000 feet²

Therefore , the area of corral build for a horse is equal to 4000 feet².

Answer:

The circumference of the garden is 62.84 ft

Step-by-step explanation:

Given;

diameter of the fountain, d = 5 feet

radius of the fountain, r = d / 2 = 2.5 feet

distance between the outer edge of the fountain and the garden = 7.5 feet

The radius of the garden = radius of the fountain + outer edge distance

The radius of the garden = 2.5 feet + 7.5 feet = 10 feet

The circumference of the garden = 2πr

The circumference of the garden = 2 x π x 10

The circumference of the garden = 62.84 ft

Therefore, the circumference of the garden is 62.84 ft

Answer:

-Martha would add $0.36 each day.

-Martha would have $7 in her coin bank after 6 days.

Step-by-step explanation:

1 quarter= $0.25

1 nickel= $0.05

1 penny= $0.01

To find the amount she adds each day, you have to add the results of multiplying each coin added on a day for its value:

1*0.25+1*0.05+6*0.01=0.25+0.05+0.06=0.36

This means that Martha would add $0.36 each day.

Then, to find the amount of money that was in her coin bank after 6 days, you have to add the amount she put on the coin bank plus the amount she added each day for the number of days:

$4.84+($0.36*6)=$4.84+$2.16=$7

According to this, Martha would have $7 in her coin bank after 6 days.
