What is the value of x?
garik1379 [7]

Answer:

<h2>x = 30°</h2>

Step-by-step explanation:

The angle 30° and 2x are complementary angles.

Two angles are called complementary angles, if their sum is one right angle (90°).

Therefore we have the equation:

30 + 2x = 90          <em>subtract 30 from both sides</em>

2x = 60      <em>divide both sides by 2</em>

x = 30

A library contains 2000 books. There are 3 times as man non fiction books. Write and solve a systems of equations to determine t
icang [17]

Answer:

The number of fiction books is <u>500</u> and non fiction books is <u>1500</u>.

Step-by-step explanation:

Given:

Total book library contains = 2000.

There are 3 times as many non fiction books as fiction books.

Now, to determine the number of non fiction books and fiction books.

Let the fiction books be x.

And the non fiction books be 3x.

Total books = 2000.

Now, to get the number of non fiction books and fiction books we put an equation:

3x+x=2000.

4x=2000.

Dividing both sides by 4 we get:

x=500.

Fiction books = 500.

Non fiction books = 3x=3\times 500=1500.

Therefore, the number of fiction books is 500 and non fiction books is 1500.

10 * 20 = 15x, x = 200/15 = 40/3

Why?

b/c if each pig eats the same amount of food, then the ratio between the number of pigs and days should remain constant.

Len [333]

Answer:

Ratio between balances will be:

(x*(1+i)*n)/(x*(1+i)^n)

Where;

x = deposit

%i = interest rate annual

n = years

Step-by-step explanation:

Lets say first deposit is x$ for both investment and annual interest rate for both investment are %i. Also, they stayed under i interest in n years:

Total balance for simple interest is:

Total balance=x*(1+i)*n

How ever total balance for compound interest is:

Total balance=x(1+i)^n
