Answer:

w = -11

Step-by-step explanation:

7w - 3w = 2(3w + 11)

Combine like terms on the left

4w = 2(3w + 11)

Divide by 2

4/2w = 2/2(3w + 11)

2w =(3w + 11)

Subtract 3w from each side

2w-3w = 3w+11-3w

-w = 11

Multiply by -1

w = -11

Two Social Security numbers (see Exercise 8.12) match zeros if a digit of one number is zero iff the corresponding digit of the
Roman55 [17]

Answer:

Proved

Step-by-step explanation:

From the given parameters, we have:

n = 9 i.e. the length of each security numbers

r = 2 i.e. 2 security numbers

Required

In 513 security numbers, 2 must have matching zeros

To do this, we make use of Pigeonhole principle.

First, we calculate the number of all security numbers not having matching zeros.

Each of the 9 digits can be selected in 2 ways.

2 ways implies that each digit is either 0 or not

So, total selection is:

Total = 2^9

Total = 512

Apply Pigeonhole principle

The principle states that: suppose there are n items in m containers, where n>m, then there is at least one container that contains more than 1 item.

This means that if there are 512 security number without matching zeros, then there is 1 (i.e. 512 + 1) with matching zeros.

512 + 1 = 513

polet [3.4K]

Answer:

y = 20   x = 6

Step-by-step explanation:

1 (3x+ 2y = 58 ------------>  -3x + -2y = -58

1x + 2y = 46 -------------->    1x + 2y = 46  

                                              ____________

                                                -2x  =  -12

                                               -----------------

                                                -2x       -2x

                                                 x = 6

3(6) + 2y = 58

18 + 2y = 58

-18          -18                                    

------------------

       2y = 40

      -----  -----

       2y     2y

y = 20
