Answer:

Associative properties of multiplication

Answer:

40 pensil

Step-by-step explanation:

Dari pertanyaan di atas, kita diberitahu bahwa:

Dita memiliki 10 kotak pensil

1 kotak pensil = 36 pensil

10 kotak pensil =

Cross Multiply

10 × 36 = 360 pensil.

Dari pertanyaan tersebut, kami diberitahu bahwa Dita memiliki 9 orang teman dan ia membagikan semua pensilnya secara merata kepada mereka di hari ulang tahunnya.

Jumlah pensil yang diterima setiap teman dihitung sebagai:

360 pensil ÷ 9 teman

= 40 pensil.

Oleh karena itu, setiap teman mendapat 40 buah pensil.

Answer:

x = -7, 7

Step-by-step explanation:

Step 1: Write out equation

-2x² - 9 = -107

Step 2: Add 9 on both sides

-2x² = -98

Step 3: Divide both sides by -2

x² = 49

Step 4: Square root both sides

x = ±7

Step 5: Arrange

-7 < 7

So x = -7, 7

Answer:

n = 1/5

Step-by-step explanation:

Let's solve your equation step-by-step.

5(n− 1 /10 )= 1/ 2

Step 1: Simplify both sides of the equation.

5(n− 1 /10 )= 1 /2

(5)(n)+(5)( −1 /10 )= 1/2

(Distribute)

5n +  −1 /2 = 1 /2

Step 2: Add 1/2 to both sides.

5n +  −1 /2  +  1 /2  =  1 /2  +  1 /2

5n=1  

Step 3: Divide both sides by 5.

5n /5  =  1 /5

n=  1 /5

Answer:

domain (-3,3]

range [0,3)

Step-by-step explanation:

The domain is the input or x values

-3 < x ≤3

in interval notation

The parentheses means not include, the bracket means include

(-3,3]

The range is the output or y values

0≤y <3

[0,3)

Hi

a number is  additive inverse if  the sum =0

so 0    as the additive inverse of 12 would be -12.

and the additive inverse of -12  is 12 (it works both ways)

The sum of number 12 and the additive inverse of 12 is given by the equation A = 12 - 12 = 0

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

Let the number be n = 12

Now , the additive inverse of the number 12 = -12

So , the sum of 12 and -12 is given by the equation ,

A = 12 - 12

A = 0

Therefore , the value of A is 0

Hence , the sum of the two numbers is 0

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{540 \: m}}}}}[/tex]

Step-by-step explanation:

Let the length and breadth be 5x and 4x respectively.

Area of rectangular field = 18000 m²

Finding the value of x

Area of rectangle = [tex] \sf{l \times b}[/tex]

Plug the values

⇒[tex] \sf{18000 = 5x \times 4x}[/tex]

Calculate the product

⇒[tex] \sf{18000 = 20 {x}^{2} }[/tex]

Swap the sides of the equation

⇒[tex] \sf{20 {x}^{2} = 18000}[/tex]

Divide both sides of the equation by 20

⇒[tex] \sf{ \frac{20 {x}^{2} }{20} = \frac{18000}{20} }[/tex]

Calculate

⇒[tex] \sf{ {x}^{2} = 900}[/tex]

Squaring on both sides

⇒[tex] \sf{x = 30}[/tex]

Replacing the value of x in order to find the value of length and breadth

Length = [tex] \sf{5x = 5 \times 30 = 150 \: m}[/tex]

Breadth = [tex] \sf{4x = 4 \times 30 = 120 \: m}[/tex]

Finding the perimeter of the rectangular field

Perimeter of rectangle = [tex] \sf{2(l + b)}[/tex]

plug the values

⇒[tex] \sf{2(150 + 120)}[/tex]

Distribute 2 through the parentheses

⇒[tex] \sf{300 + 240}[/tex]

Add the numbers

⇒[tex] \sf{540 \: m}[/tex]

Answer:

The length of XY is 32

Step-by-step explanation:

Notice that you have a bisector segment (that divides the segment XY  into two equal parts.

since these parts are equal, they must satisfy:

3 x + 1 = 8 x - 24

so, let's solve for x, grouping terms with x on the right of the equal sign, and numerical terms on the left:

1 + 24 = 8 x - 3 x

25 = 5 x

then x = 25/5 = 5

then,now you can find the length of XY as the addition of both parts:

3 x + 1 + 8 x - 24 = 3 (5) +1 + 8 (5) - 24 = 16 + 16 = 32
