Travka [436]

If you would like to know solve the equation 2/9 * b = 1/3 * b - 7, you can calculate this using the following steps:

2/9 * b = 1/3 * b - 7
2/9 * b - 1/3 * b = -7
2/9 * b - 3/9 * b = -7
-1/9 * b = -7
1/9 * b = 7 /*9
b = 7 * 9
b = 63

Karo-lina-s [1.5K]

Answer:

The correct option is a.

Step-by-step explanation:

Given information:

Number of elements in set A = 4

Number of elements in set B = 3

We need to find n(A × B). It means we have to find the number of elements in set A × B.

If P and Q are two sets with elements m and n respectively, then the number of element in the set P × Q is m × n.
