You can't. That's as simplified as it gets :)

1. Given that U = {1, 2, 3, ..., 10}, S = {3, 5, 7, 9} and T = {4, 5, 6, 7}, find S-T

The set of, S - T = {3, 9}

Define Set Operation.

To obtain a combination of components according to the operation done on them, the set operations are conducted on two or more sets.

In a set theory, there are three major types of operations performed on sets, such as:

1) Union of sets (∪)

2) Intersection of sets (∩)

3) Difference of sets ( – )

We know, S -T = S ∩ T'

Given, universal set is U = {1, 2, 3, ..., 10}

S = {3, 5, 7, 9} and T = {4, 5, 6, 7}

Now, find T' (T's compliment),

The complement of set T is defined as a set that contains the elements present in the universal set but not in set T.

T' = {1, 2, 3, 8, 9, 10}

given, S = {3, 5, 7, 9}

Find, S ∩ T'

S ∩ T' = {3, 5, 7, 9} ∩ {1, 2, 3, 8, 9, 10}

The intersection of two sets S and T is a subset of the universal set U and contains elements that are present in both sets S and T. It is represented by the symbol "∩".

so, S ∩ T' = {3, 9}

Hence, S - T = S ∩ T' = {3, 9}

PLEASE I NEED HELP

klemol [59]

Answer: 0.25 feet

Step-by-step explanation:

Given: Jonathon has paper strips that are all equal in length.

Let x be the length of each paper strip.

Since John lines them up end to end, the length of the line of paper strips= 3 feet

Also total strips used= 12

Therefore, length of line of strips= $12x=3\ feet$

$\\\Rightarrow\ x=\frac{1}{4}\ feet\\\Rightarrow\ x= 0.25\ feet$

hence, if Jonathan is correct then the length of each strip will be 0.25 feet.

What are the numerical measures of the angles?

vredina [299]

ANSWER

The sum of m∠DEA and m∠AEB is 180°.

Reason: The sum of angles on a straight line is always 180°.

$(x + 25)+(9x + 10)=180 \degree$

Group like terms to get,

$x+9x=180-25-10$

Simplify, and get,

$10x = 145$

Divide both sides by 10 to get,

$x = 14.5$

We substitute this value to get the required angles.

$m \: ∠DEA=x+25$

$m \: ∠DEA = 14.5 + 25 = 39.5 \degree$

$m\:∠AEB=9x+ 10$

$m\:∠AEB = 9(14.5) + 10$

$m\: ∠AEB=130.5 + 10 = 140.5 \degree$

In the system of equations below, which variable would it be easiest to solve for?

Maru [420]

Answer:

<h3> The first: The easiest to solve for is x in the first equation.</h3>

Step-by-step explanation:

To get x from first equation you just need to subtract 4y from both sides.

The rest of variables needs two operations to get variable - subtracting and then dividing.
