Verified answer

The value of |A| = 6 and |BI = 4.

Step-by-step explanation:

Be discovered:

Set A consists of positive even multiples of 5 less than 60.

Set B consists of odd multiples of 7 from 1 to 60.

Question:

Find |A| and |BI.​

Asked:

The first step is to find a multiple of 5 .

5 x 1 = 5

5 x 2 = 10

5 x 3 = 15

5 x 4 = 20

5 x 5 = 25

5 x 6 = 30

5 x 7 = 35

5 x 8 = 40

5 x 9 = 45

5 x 10 = 50

5 x 11 = 55

5 x 12 = 60

Multiples of 5 = {5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, ... }

The second step, we determine the multiples of 5 are even less than 60.

An even multiple of 5 is less than 60, which is 10, 20, 30, 40, 50, 60.

The third step is to find a multiple of 7 that is less than 60.

7 x 1 = 7

7 x 2 = 14

7 x 3 = 21

7 x 4 = 28

7 x 5 = 35

7 x 6 = 42

7 x 7 = 49

7 x 8 = 56

7 x 9 = 63

Multiples of 7 = {7, 14, 21, 28, 35, 42, 49, 56, 63, ...}

In the fourth step, we determine the odd multiple of 7 is less than 60.

odd multiples of 7 are less than 60, namely: 7, 21, 35, 49.

The fifth step we determine the value of |A| = 6 and |BI = 4.
