If 2x + 7 = -21, what does 2 - x equal?

Answer:

D

Step-by-step explanation:

Here, we want to know which of the options would be true if we replace the term in the box ( D) by the value 1,537.

The correct option here is thus D

What we have here would be

1537 > 1,357

This can be read as 1537 is greater than 1,357 which is correct

Answer:

x = smaller number

3x + 15 = the larger number

x + 3x + 15 = 63

4x = 48

x = 12

3(12) + 15 = 51

so the smaller number is 12 and the larger number is 51

Answer: 4746.09375 dollars (just round down to nine cents)

Step-by-step explanation:

The revenue in the 5th night in two will be $4746.093.

A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.

For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.

Revenue in the first night = $15000

Since revenue of new night is 75% of the previous night

So,

2nd night = 15000 × 75/100 = 11250

3rd night = 8437.5

So the given sequence is ;

15000, 11250, 8437.5 ... it is a GP series.

First term(a) = 15000

Common ratio(r) = 11250/15000 = 0.75

The nth term of a GP is given by ;

[tex]a_{n} = ar^{n-1}[/tex]

So for 5th-night n = 5

So,

a₅ = ar⁵⁻¹

a₅ = 15000(0.75)⁴

a₅ = 4746.093

Hence "The revenue in the 5th night in two will be $4746.093".

Greetings from Brasil...

According to the statement of the question, let X be any number. If this number X has to be less than 15, we can write:

The number is less than 15 and  it can be represented by x < 15.

It is given in the question that a number is less than 15.

We have to represent it by translating inequalities.

How will we represent 10 times of x ?

The answer will be 10x.

Let's assume the number is X.

⇒ X <  15 (as per the question)

< symbolic is for less than i.e., X is less than 15.

X represents an unknown value, i.e., numbers less than 15 are 14, 13, 12,...etc.

Thus , if a number is less than 15 , it can be represented by x < 15.

  Left_M = L.C.M / L_Deno = 4

  Right_M = L.C.M / R_Deno = 3

Making Equivalent Fractions :

4.3      Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example :  1/2   and  2/4  are equivalent,  y/(y+1)2   and  (y2+y)/(y+1)3  are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

  ——————————————————  =   —————

        L.C.M              12

When a fraction equals zero

5.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 b+36

 ———— • 12 = 0 • 12

  12  

Now, on the left hand side, the  12  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  b+36  = 0

Solving a Single Variable Equation:

5.2      Solve  :    b+36 = 0  

Subtract  36  from both sides of the equation :  

                     b = -36

Step-by-step explanation:

Answer:

Quite simply. The answer is X=6

Since you have a full fraction, you can find a common denominator in both fractions and multiply. (The common denominator would be 8, so you would multiply 4 by 2 to get 8. Do the same thing to the top, do multiply 3 by 2 to get 6). Now the fraction is 6/8, and since it's equal to incomplete fraction, you know X is 6.
