Mathematics
1 answer:
Gala2k [10]3 years ago
6 0

Answer/Step-by-step explanation:

2(3x - 1) = 2*3x 2*-1 = 6x - 2

(x*y)2 = (xy)2 = 2xy

2(2x - 3) = 2*2x 2*-3 = 4x - 6

3x + 4x + 2 = (3x + 4x) + 2 = 7x + 2

7x - 7 = 7(x) - 7(1) = 7(x - 1)

x(6 + 9) = x(15) = 15x

2 + 9x + 1 + 3x = (9x + 3x) + (2 + 1) = 12x + 3

4(x + 2) + x = 4x + 8 + x = 4x + x + 8 = 5x + 8

In order to do mean you have to add all of the numbers in the list together. then divide them by the total amount of numbers (ex. 7,9,3,2,5. you would add all of these up 7+9+3+2+5=26 then you would divide that by 5 because there are five numbers in the list.

STatiana [176]

Answer:

<em><u>The number of students that like only Nokia </u></em>

<h2>= 30</h2>

Step-by-step explanation:

consider N the number of students who like Nokia → N=?

               T the number of students who like Techno → T=35

Statement 1: In a class of 40 students, 5 like neither Nokia nor Techno

we can translate it like this: 35 student like Nokia or Techno

we can note it like this : T∪N= 35

Statement 2: 30 like Techno and Nokia

we can note it : T∩N = 30

using a rule concerning the number of element of a set :

T∪N = N + T - T∩N

then

35 = N + 35 - 30

⇒ N - 30 = 0

⇒ N = 30
