Step-by-step explanation:

1. Since 39 is 3/5 of the club, divide by 3 to get 1/5 of the club

2. 1/5 of the club is 13 people

3. Multiply 13 by 5 to get 5/5 of the club (which is the whole club)

4. The whole club is 65 people

5. You can check it because 65×3/5=39

Question4..........................
belka [17]

Answer:

see explanation

Step-by-step explanation:

Given

- (\frac{2}{5} )²

The negative is outside the bracket and is not squared, that is

= - \frac{2}{5} × \frac{2}{5}

= - \frac{2(2)}{5(5)} = - \frac{4}{25}

Given

\frac{5^3}{3} = \frac{5(5)(5)}{3} = \frac{125}{3}

Answer this question correctly please and then I’ll mark you as a brainliest!
Studentka2010 [4]

Answer:


Step-by-step explanation:

1) 2 - (- 8) = 2 + 8 = 10


2) 2/5 + (- 1/5) = 2/5 - 1/5 = 1/5


3) We can find the common denominators through the least common multiple between the denominators:


4,12 | 2

2, 6 | 2

1, 3 | 3

1, 1 (2 × 2 × 3 = 12)


Then, 12 is the least common denominator.


4) 8 (1/4) + 10 (2/5) + 7 (5/8)

8 (1/4) = 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 1/4 = 33/4


10 (2/5) = 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 2/5 = 52/5


7 (5/8) = 8/8 + 8/8 + 8/8 + 8/8 + 8/8

+ 8/8 + 8/8 + 5/8 = 61/8


33/4 + 52/5 + 61/8


Employing the least common denominator:


4, 5, 8 | 2

2, 5, 4 | 2

1, 5, 2 | 2

1, 5, 1 | 5

1, 1, 1 (2 × 2 × 2 × 5 = 40)


(40 ÷ 4 × 33)/40 + (40 ÷ 5 × 52)/40 + (40 ÷ 8 × 61)/40

330/40 + 416/40 + 305/40

1051/40

L'età media di Aldo, Bruno, Carlo e Davide è 16 anni. Se non si tiene conto di Davide, l'età media dei tre rimanenti sale a 18.
photoshop1234 [79]

Answer:

Davide's age is 10.

L'età di Davide è 10.

Step-by-step explanation:

The average age of Aldo, Bruno, Carlo and Davide is 16 years.

I am going to say that:

x is Aldo's age.

y is Bruno's age.

z is Carlo's age.

w is Davide's age.

Average of the 4 is 16 years.

This means that:

16 = \frac{x + y + z + w}{4}

x + y + z + w = 64

If we do not consider Davide, the mean is 18. So

18 = \frac{x + y + z}{3}

x + y + z = 54

Replacing in the first equation:

x + y + z + w = 64

54 + w = 64

w = 10

Davide's age is 10.

L'età di Davide è 10.
