order to buy the television

Answer:

20 cm

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse h is equal to the sum of the squares on the other 2 sides, that is

h² = 12² + 16² = 144 + 256 = 400 ( take the square root of both sides )

h = [tex]\sqrt{400}[/tex] = 20

Answer:

y=5+2x

Step-by-step explanation:

The Solution of the given 2x - y = -5 expression for y will be y = 2x 5.

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.

Given, an algebraic expression 2x - y = -5

Solution of the given expression for the variable y

=> 2x - y = -5

Simplifying the equation

=> 2x - y = -5

add variables y and 5 on both sides

=> 2x - y +y + 5 = -5 + y + 5

=> 2x +5 = y

Therefore, the Solution of the given expression for y will be y = 2x + 5.

Answer:

8 bracelets

Step-by-step explanation:

Given

Yellow = 40 beads

Red = 64 beads

Required

Highest number of bracelets

To answer this question, we simply need to determine the highest common factor of the given parameters.

40 = 2³ * 5

64 = 2⁶

HCF = 2³

HCF = 2 * 2 * 2

HCF = 8

Hence, the maximum number of bracelets is 8

Answer:

The answer is -1/9

Step-by-step explanation:

The slope of a perpendicular line is the opposite reciprocal.

To find the slope you take the given slope (9) and flip the reciprocal which results it turning into 1/9.

Then make it the opposite value. Like switching a negative to a positive or a positive to a negative. For this case, you make 1/9 into a -1/9

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the expression is  4(x+3)=52. To prove put the value of x = 10,

4(x+3)=52

4 ( 10 + 3 ) = 52

4 x 13 = 52

52 = 52

Hence, the expression is true for the value of x = 10.

[tex]x=6[/tex]

Step-by-step explanation:

[tex]\frac{1}{2} (-10x+4)=-4(-3+2x)+8[/tex]

To make things easier, let's first start by rewriting [tex]\frac{1}{2}[/tex] as a decimal:

[tex].5(-10x+4)=-4(-3+2x)+8[/tex]

Distribute [tex].5[/tex] into [tex](-10x+4)[/tex]:

[tex]-5x+2=-4(-3+2x)+8[/tex]

Distribute [tex]-4[/tex] into [tex](-3+2x)[/tex]:

[tex]-5x+2=12-8x+8[/tex]

Combine like terms:

[tex]-5x+2=20-8x[/tex]

Add [tex]8x[/tex] to both sides of the equation:

[tex]3x+2=20[/tex]

Subtract [tex]2[/tex] from both sides of the equation:

[tex]3x=18[/tex]

Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]3[/tex]:

[tex]x=6[/tex]

_

Check your work by substituting [tex]6[/tex] into the initial equation:

[tex].5(-10(6)+4)=-4(-3+2(6))+8[/tex]

[tex].5(-60+4)=-4(-3+12)+8[/tex]

[tex]-30+2=12-48+8[/tex]

[tex]-28=-28[/tex]

The answer is correct!

Answer:

x = 6

Step-by-step explanation:

We know that,

( + ) × ( + ) = ( + )

( - ) × ( - ) = ( + )

( - ) × ( + ) = ( - )

Let us solve it now.

[tex]\sf \dfrac{1}{2} (-10x+4)=-4(-3+2x)+8[/tex]

Solve the brackets.

[tex]\sf -\dfrac{10x}{2} +\dfrac{4}{2} =+12-8x+8\\\\\sf -5x +2 =20-8x[/tex]

Add 8x to both sides.

[tex]\sf -5x+8x+2=20\\\\3x+2=20[/tex]

Subtract 2 from both sides.

[tex]\sf 3x=20-2\\\\3x=18[/tex]

Divide both sides by 3.

Answer:

k = 31

Step-by-step explanation:

Solve for k:

35 - k = 4

Subtract 35 from both sides:

(35 - 35) - k = 4 - 35

35 - 35 = 0:

-k = 4 - 35

4 - 35 = -31:

-k = -31

Multiply both sides of -k = -31 by -1:

(-k)/(-1) = 31

(-1)/(-1) = 1:

Answer: k = 31
