Answer:
Step-by-step explanation:
If ' n ' is the cardinal number of a set, the number of subsets of a given set can be obtained by using the formula 2ⁿ
Given,
N = { 1 , 42 , 65 , 12 , 31 , 27 }
where n ( total number of elements ) = 6
So, the number of possible subsets of set N :
= 2ⁿ
= 2⁶
= 2 × 2 × 2 × 2 × 2 × 2
= 64

Answer:
z = 9
Step-by-step explanation:
To find the solution, undo what is done to z. You can start by adding 27 to both sides of the equation.
6z -27 +27 = 27 +27
6z = 54 . . . . . simplify
Now, you can divide by 6 to make the coefficient of z be 1.
6z/6 = 54/6
z = 9 . . . . . . . simplify
