PLEASE ANSWER THISSS<br> AAAAAAAAAAAAAAA

Butoxors [25]

Answer:

147

Step-by-step explanation:

E = greatest common factor of 22 and 30 = 2

F = least common multiple of 3 and 8 = 24

G = 3 * (7 + 10) = G + 30 = 81

3 * 7 + 3 * 10 = G + 30

21 + 30 = G + 30

51 = G + 30

G = 81

H = 5 * (3 + H) = 15 + 45 = 40

5 * 3 + 5 * H = 15 + 45

15 + 5 * H = 60

20 * H = 60

H = 60 - 20

H = 40

E = 2 + F = 24 + G = 81 + H = 40

2 + 24 + 81 + 40 = 147

This was fun lol

Which expression equals a number that is NOT a rational number?

rewona [7]

$\frac{3\pi.3^3}{7}$ is not included as a rational number !

<u>Step-by-step explanation:</u>

Here we have , following expressions & we need to identify which of the following is not a rational number . Let's find out:

We know that , Rational Number : A number which can be expressed in form of p/q , where q is not equal to zero !

Here Expressions are:

$\frac{3\pi . 3^3}{7\pi}$ :

Let's evaluate this expression

⇒ $\frac{3(\pi) ( 3^3)}{7(\pi)}$

⇒ $\frac{3^4}{7}$

Therefore , It is a rational number ! .

$\frac{-18}{5}$ :

Let's evaluate this expression

⇒ $\frac{-18}{5}$

Therefore , It is a rational number ! .

$\frac{5}{3-7-9}$ :

Let's evaluate this expression

⇒ $\frac{5}{3-16}$

⇒ $\frac{-5}{13}$

Therefore , It is a rational number ! .

$\frac{3\pi.3^3}{7}$ :

Let's evaluate this expression

⇒ $\frac{3\pi.3^3}{7}$

⇒ $\frac{\pi.3^4}{7}$

Therefore , It is not a rational number , as pi is included ! .
