Answer:
259
Step-by-step explanation:
491+624=1115. 1374-1115=259
x=3 or x= -8
{f, a}
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 n (X - Y) = elements in X and (X - Y)
X n (X - Y) = {f, a}
Answer: GCF = 30 for the values 120, 150
The factors of 120 are: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
The factors of 150 are: 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150
Then the greatest common factor is 30.
