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.

When a graphed line is vertical, it indicates that the relation is ?

GuDViN [60]

Answer:When a vertical line is placed across the plot of this relation, it intersects the graph more than once for some values of x. If a graph shows two or more intersections with a vertical line, then an input (x-coordinate) can have more than one output (y-coordinate), and y is not a function of x.

John and Ariana bought school supplies, John spent $10.65 on 4 notebooks and 5 pens. Ariana spent $7.50 on 3 notebooks and 3 pen

timurjin [86]

Cost of 1 notebook is $ 1.85 and cost of 1 pen is $ 0.65

<h3><u>Solution:</u></h3>

Let "a" be the cost of 1 notebook

Let "b" be the cost of 1 pen

Given that John spent $10.65 on 4 notebooks and 5 pens

cost of 1 notebook x 4 + cost of 1 pen x 5 = 10.65

4a + 5b = 10.65 ------ eqn 1

Given that Ariana spent $7.50 on 3 notebooks and 3 pens

3a + 3b = 7.50 ----- eqn 2

Let us solve eqn 1 and eqn 2 to get the values of "a" and "b"

Multiply eqn 1 with 3

12a + 15b = 31.95 ---- eqn 3

Multiply eqn 2 with 4

12a + 12b = 30 ------ eqn 4

Subtract eqn 4 from eqn 3

12a + 15b = 31.95

12a + 12b = 30

(-) ---------------------

3b = 1.95

b = 0.65

Substitute b = 0.65 in eqn 1

4a + 5(0.65) = 10.65

4a = 7.4

a = 1.85

Thus cost of 1 notebook is $ 1.85 and cost of 1 pen is $ 0.65

A quadrilateral has angles that measure 56°, 97°, and 136°.

Serhud [2]

The sum of the interior angles can be represented by:
180(n-2)
180 x 2 = 360
Therefore, the sum of the angles must be 360.

56 + 97 + 136 = 289
360 - 289 = 71<span>°
