Adults = x

Senior Citizens = y

x + y = 529......1

25x + 15y = 9745...2

Multiply (1) by 15

15x + 15y = 7935....3

25x + 15y = 9745....2

Subtract 3 from 2

10x = 1810

 

x = 181

Substitute x = 181 in

Eq (1)

x + y = 529

181 + y = 529

y = 529 - 181

y = 348

181 adults and 348 Senior Citizens

Hope this helps.

What what are the rules for addition and subtraction with numbers in scientific notation?
andriy [413]
Addition and Subtraction in Scientific Notation. A number written in scientific notation is written as the product of a number between 1 and 10 and a number that is a power of 10. That is, it is written as a quantity whose coefficient is between 1 and 10 and whose base is 10.

Factor the expression completely over the complex numbers.
nekit [7.7K]

Answer:

The factor form of given expression is (x-4)(x-2i)(x+2i).

Step-by-step explanation:

The given expression is

x^3-4x^2+4x-16

It can be written as

f(x)=x^3-4x^2+4x-16

According to the rational root theorem, all possible rational roots are in the form of

\frac{a_0}{a_n}

Where, a₀ is constant term and a_n is leading coefficient.

f(4)=4^3-4(4)^2+4(4)-16=0

Since the value of f(x) is 0 at x=4, therefore 4 is a root of the function and (x-4) is a factor of given expression.

Use synthetic method to find the remaining factors.

(x^3-4x^2+4x-16)=(x-4)(x^2+4)

(x^3-4x^2+4x-16)=(x-4)(x^2-(2i)^2)

(x^3-4x^2+4x-16)=(x-4)(x-2i)(x+2i)

Therefore the factor form of given expression is (x-4)(x-2i)(x+2i).

A number to the 12th power divided by the same number to the 9th power equals 216. What is the number?
Annette [7]

Answer:

The given such number is 6.

Step-by-step explanation:

Let the given such number  = m

Now, according to the question, the given expression is:

\frac{(m^{12}) }{(m^{9}) }   =  216

By the LAW OF EXPONENTS:

\frac{x^a}{x^b}  = x^{(a-b)}

⇒Here \frac{m^{12}}{m^9}  = m^{(12-9)}  = m^{(3)}

or, the given expression becomes m^3 =  216\\\implies m = \sqrt[3]{216}  = 6

or, m  = 6

Hence, the given such number is 6.
