Step-by-step explanation:
Answer:
{f, a}
Step-by-step explanation:
Given the sets:
X = {d, c, f, a}
Y = {d, e, c}
Z ={e, c, b, f, g}
U = {a, b, c, d, e, f, g}
To obtain the set X n (X - Y)
We first obtain :
(X - Y) :
The elements in X that are not in Y
(X - Y) = {f, a}
X n (X - Y) :
X = {d, c, f, a} intersection
(X - Y) = {f, a}
X n (X - Y) = elements in X and (X - Y)
X n (X - Y) = {f, a}
Answer:
270 coins
n + p
Step-by-step explanation:
Given that :
Number of nickels = 140
Number of pennies = 130
The total numbers coins had:
Number of Nickel + number of pennies
140 + 130 = 270 coins
If Number of nickels = n ; number of pennies = p
The total number of coins :
Number of Nickel + number of pennies
n + p
