The required number is -3 which when added to the numerator and to the denominator of 5/8 results in a fraction whose value is 0.4.

<h3>What is a fraction?</h3>

Fraction is the ratio of a particular part to the whole parts of an object. A fraction has a numerator and a denominator.

<h3>Calculation:</h3>

The given fraction is 5/8

Consider a number as 'x' which is added to both the numerator and the denominator of the given fraction.

So,

(5 + x)/(8 + x)

Since it is given that the result is 0.4 i.e., 4/10, we can write

(5 + x)/(8 + x) = 4/10

⇒ 10(5 + x) = 4(8 + x)

⇒ 50 + 10x = 32 + 4x

⇒ 10x - 4x = 32 - 50

⇒ 6x = -18

⇒ x = -18/6

∴ x = -3

Therefore, the required number is -3.

Check:

(5 + (-3))/(8 + (-3)) = (5 - 3)/(8 - 3) = 2/5 = 0.4

Given the function f(x) = √x-8 + 3 which of the following is the value of f(24)
kvasek [131]

Answer:

The answer is 7.

Step-by-step explanation:

You have to substitute the value of x into the function :

f(x) =  \sqrt{x - 8}  + 3

f(24) =  \sqrt{24 - 8}  + 3

f(24) =  \sqrt{16}  + 3

f(24) = 4 + 3

f(24) = 7
