ANSWER

There are 16 fiction books

EXPLANATION

Let the number of nonfiction books be

n

Then the number of fiction books is

f=\frac{2n}{5}

If there are 56 books in the library, then

n + f= 56

This implies that,

n + \frac{2n}{5} = 56

Multiply through by 5 to get,

5n + 2n = 280

7n= 280

Divide through by 7 to get,

n = \frac{280}{7}

n= 40

Therefore the number of fiction books

f=\frac{2\times40}{5}=16

Or

f=56 - 40 = 16

An air traffic controller is tracking two planes.To start Plane A was at an altitude of 990 meters and plane B was at an altitud
soldi70 [24.7K]

The equation representing when the two planes would be at the same altitude is 9x=486

<h3>In terms of mathematics, what is an equation?</h3>

Equation: A declaration that two expressions with variables or integers are equal. In essence, equations are questions, and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics.

From (a) we get that: Altitude of Plane A = 990-18x

Altitude of Plane B = 1476-27x

make 890 - 18x = 1476-27x

-18x+27 x = 1476-890

9x=486

X= 54

so pass 54 seconds will the two plane at the same altitude.

It takes 46 minutes for 10 people to paint 3 walls
Mice21 [21]

Answer:

It takes 46 minutes for 10 people to paint 3 walls

It takes 92 minutes for 10 people to paint 6 walls (twice as long because you have twice as many walls)

You only have 4 people to paint the walls instead of 10 people

Therefore it will take 2.5 times as long (10/4=2.5)

2.5*92=230 minutes
