Let A U B = {a,b,c,d,e,x,y,z)andA n B = {b, e,y}. . a. If B - A = {x,Z}, then A=_________

Leona [35]

A U B = {a, b, c, d, e, x, y, z}

A ∩ B = {b, e, y}

a. B - A is the complement of A in B; that is, from set B, we remove any elements found in A. Both sets contain b, e, and y, so if B - A = {x, z}, then

B = {b, e, x, y, z}

and so A makes up the rest of the given union,

A = {a, b, c, d, e, y}

b. A and B are non-empty, since their union and intersection are also non-empty. So if A - B = ∅, this means A contains all the elements of B, though B may have more elements than A. In other words, A is a subset of B, which means A U B = B. So

B = {a, b, c, d, e, x, y, z}

c. If B = {b, e, y, z}, then A makes up the rest of their union,

A = {a, b, c, d, e, x, y}

Then

A - B = {a, c, d, x}

List all integers between −100 and 100 that are congruent to −1 modulo 25.

777dan777 [17]

"-1 modulo 25" is "1 less than a precise multiple of 25".
So what are the exact or precise multiples of 25 in the appropriate interval?
It is -75, -50, -25, 0, 25, 50, 75, and 100.
Now just subtract 1 from each of them.

So the answers are -76, -51, -26, -1, 24, 49, 74, and 99.

If the numerator of a fraction is increased by six, the value of the fraction will increase by one. If the denominator of the or

Alchen [17]

Answer:

$\dfrac{7}{6}$

Step-by-step explanation:

Let $\dfrac{a}{b}$ be the original fraction.

If the numerator of a fraction is increased by six, the value of the fraction will increase by one. Hence,

$\dfrac{a+6}{b}=\dfrac{a}{b}+1$

If the denominator of the original fraction is increased by 36, the value of the original fraction will decrease by one. Hence,

$\dfrac{a}{b+36}=\dfrac{a}{b}-1$

Add these two equalities:

$\dfrac{a+6}{b}+\dfrac{a}{b+36}=\dfrac{a}{b}+1+\dfrac{a}{b}-1\\ \\\dfrac{a+6}{b}+\dfrac{a}{b+36}=2\dfrac{a}{b}\\ \\\dfrac{a}{b+36}=\dfrac{2a-(a+6)}{b}\\ \\\dfrac{a}{b+36}=\dfrac{a-6}{b}\\ \\ab=(a-6)(b+36)\\ \\ab=ab+36a-6b-216\\ \\36a-6b-216=0\\ \\6a-b-36=0\\ \\b=6a-36$

Substitute it into the first equation:

$\dfrac{a+6}{6a-36}=\dfrac{a}{6a-36}+1\\ \\\dfrac{a+6}{6(a-6)}=\dfrac{a}{6(a-6)}+1\\ \\a+6=a+6(a-6)\\ \\a+6=a+6a-36\\ \\6a=6+36\\ \\6a=42\\ \\a=7\\ \\b=6\cdot 7-36=42-36=6$

Thus, the initial fraction was

$\dfrac{7}{6}$
