<h2>Answer:</h2>

The mathematical expression 2 ∈ V means that:

        2 is an element of set V.

<h2>Step-by-step explanation:</h2>

We know that for any set A with elements as:

            A={a,b,c,d}

We see that that the element a,b,c and d all belongs to the set A and is represented by the symbol:

          a ∈ A, b ∈ A , c ∈ A and d ∈ A

i.e. they represent that the element is contained in that set.

Here we  2 ∈ V

This means for a set V of elements.

The element 2 belongs to the set.

i.e. it is a member of the set.

One number is 2 more than 3 times another. Their sum is 22. Find the numbers. 8, 14 5, 17 2, 20 4, 18 10, 12
xxTIMURxx [149]

9514 1404 393

Answer:

  (b)  5, 17

Step-by-step explanation:

You can try the answer choices easily enough.

  2 +3×8 ≠ 14

  2 +3×5 = 17 . . . . this choice works (5, 17)

  2 +3×2 ≠ 20

  2 +3×4 ≠ 18

  2 +3×10 ≠ 12

__

Or, you can solve the equation:

  x + (2 +3x) = 22

  4x = 20 . . . . . . . . subtract 2

  x = 5 . . . . . . . . . . divide by 4

The numbers are 5 and (22 -5) = 17.

Rudik [331]

The price of the one notebook will be Rs. 10.6

  • Let the price of one notebook be x.

If Haseena bought 1 pencil box, 4 pencils and 4 notebooks from a store, with a total of Rs. 95 paid in all, then;

1x + 4x + 4x = 95

9x = 95

x = 95/9

x = 10. 6

Hence the price of the one notebook will be Rs. 10.6
