Answer:

= 8

Step-by-step explanation:

2x = 2 × 3 is 6 because f(3) then + 2 is 8

3 x 2 = 6

6 + 2 = 8

The correct answer is 8

(Hope this helps can I pls have brainlist (crown)☺️)

Step-by-step explanation:

a/q

x + x - 3 + 2x - 9 = 36

4x - 12 = 36

4x = 36 + 12 = 48

x = 48/4 = 12

x = 12

so,

x = 12

x - 3 = 12 - 3 = 9

2x - 9 = 2(12) - 9 = 15

we know,

area = 1/2 × base × height

so,

→ 1/2 × 12 × 9

→ 1 × 6 × 9

→ 54 inches.

Answer:x=6

Step-by-step explanation:

x+5x=36

Step 1: Simplify both sides of the equation.

x+5x=36

(x+5x)=36(Combine Like Terms)

6x=36

6x=36

Step 2: Divide both sides by 6.

[tex]\frac{6x}{6} =\frac{36}{6}[/tex]

Answer:

690

Step-by-step explanation:

(323+1715)-(1135+213)

(2038)-(1348)

=690

The value of the expression is 690

An expression is combination of variables, numbers and operators.

The given expression is (323+1715)−(1135+213)

We have to find the value of expression

By using PEMDAS rule we solve the expression

Let us find the value in parenthesis

2038 -1348

We get 690

Hence, the value of the expression is 690

The solution is: It occurred 90 times does the digit 5 occur in all the numbers from 100-999 .

An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.

For instance, the sequence 5, 7, 9, 11, 13, 15.. . is an arithmetic progression with a common difference of 2.

The nth term of AP : a_n = a + (n – 1) × d

here, we have,

Explanation:

Here, we want to know the number of times the digit occurs

We can solve this with arithemetic progression

The first term here is 105, while the last term is 995

However, the difference between each occurrence is 10

Thus, applying the formula:

T_n = a + (n-1) d

T_n is the last term which is 995

a is the first term which is 105

d is the common difference which is 10

n is the number of terms which we want to calculate

Substituting these values, we have it that:

995 = 105 + (n-1) 10

so, we get,

n = 900/10

  =90

Hence, It occurred 90 times does the digit 5 occur in all the numbers from 100-999 .

Additional comment

If your calculator does not have a % key, you can perform the multiplication by converting the percentage to a decimal or using it as a fraction. The % symbol is interchangeable with /100, so 84% = 84/100. Of course, this is eighty-four hundredths, which can also be written 0.84.

Any spreadsheet will accept direct input of numbers with an attached % symbol, so you can use one of those for this calculation, also.

Answer: You need to prove that ABCD is a rhombus because it's diagonals are always perpendicular, no matter what.

A rhombus is a quadrilateral and:

- its opposite angles have equal measure.

- The two diagonals of a rhombus are perpendicular; that is, a rhombus is an orthodiagonal quadrilateral.

- Its diagonals bisect opposite angles.

QUESTION. What is the Scale factor of 35 to 42

--------------------------------------

[tex]\boxed {\tt 25/35}[/tex]

---------------------------------------

The Scale Factor of 35/42 is the relative difference of one fraction or number (a) to another fraction or number prime (a′). In other words, 35/42 is what you multiply (number a) by to get (number a prime).

In a multiplication problem, we have a multiplier, multiplicand, and a product. You could say that (a) is the multiplier, the Scale Factor of 35/42 is the multiplicand, and (a′) is the product:

multiplier × multiplicand = product

multiplier × scale factor = product

a × 35/42 = a′

In the calculator below, you can enter the multiplier (a) as a fraction. We will then multiply it by the Scale Factor of 35/42 and give you the product (a′) in its simplest form possible.

Answer:

sin θ . tan θ

Step-by-step explanation:

Note : -

sec ( - θ ) = sec θ

Formula / Identity : -

sec θ = 1 / cos θ

sec ( - θ ) - cos θ

= [ 1 / cos θ ] - cos θ

{ LCM = cos θ }

= [ 1 / cos θ ] - [ cos²θ / cos θ ]

= [ 1 - cos²θ ] / cos θ

{ 1 - cos²θ = sin²θ }

= sin²θ / cos θ

{ sin²θ = sin θ . sin θ }

= sin θ . sin θ / cos θ

{ sin θ / cos θ = tan θ }

= sin θ . tan θ

Hence, simplified.
