6. If n (E) = 40, n (A) = 22, n (ANB) = 8 and n ((AUB)') = 6, determine n(B)​

Answer:

X = 5

Step-by-step explanation:

4x - 7 = 13

4x = 13 + 7

4x = 20

x = 20 / 4

x = 5

Hope it Helps :) !!

The solution of the given equation will be; X = 5

We know that the equation is defined as an expression that shows the relationship between two or more numbers and variables.

WE are given the statement as;

"7 less than 4 times a number equals 13 ​"

The equation becomes as;

4x - 7 = 13

Now solving for x;

4x = 13 + 7

4x = 20

Divide;

x = 20 / 4

x = 5

The value of x will be; x = 5

w is no more than 7 is different

Answer:

W is no more than 7

Step-by-step explanation:

W is greater than or equal to -7 is (W>_-7)

W is no more than 7 is (W<_7)

W is no less than -7 is (W>_7)

W is at least -7 is (W>_7)

Out of all of these, w is no more than 7 is the only different expression

Answer:

[tex]x = -4[/tex]

Step-by-step explanation:

To solve this equation, we need to apply the distributive property, combine like terms, and get x on one side of the equation.

First, let's apply the distributive property to all parts of the equation:

[tex]0.5(4x-2) - 2(3x+3) = 9+2x + 8[/tex]

[tex]2x - 1 - 6x - 6 = 9 + 2x + 8[/tex]

Combine like terms:

[tex]-4x - 7 = 2x + 17[/tex]

Add 4x to both sides:

[tex]-7 = 6x + 17[/tex]

Add -7 to both sides:

[tex]0 = 6x + 24[/tex]

Subtract 24 from both sides:

[tex]6x = -24[/tex]

Divide both sides by 6:

[tex]x = -4[/tex]

Hope this helped!

Answer:

[tex]x = \frac{82}{3}[/tex]

Step-by-step explanation:

[tex](\frac{3}{4} )x = \frac{41}{2}[/tex]

[tex]\frac{3x}{4} = \frac{41}{2}[/tex]

[tex]\frac{3x}{4} * 4 = 4 * \frac{41}{2} \\3x = \frac{41 }{2} * 2 * 2\\3x = 41 *2 \\3x = 82 \\[/tex]

[tex]\frac{3x}{3} = \frac{82}{3}[/tex]

[tex]x = \frac{82}{3}[/tex]

The number is   [tex]\frac{82}{3}[/tex]  .

Fractions , represent a numerical value that expresses a part of a whole. The whole can be any number, a specific value, or a thing. Fractions are represented in the form of p/q. For example, ¼, ½, ¾, and so on.

According to the question

Let the number be x .

If 3/4 of a certain number is equal to 41/2

i.e

[tex]\frac{3}{4}x = \frac{41}{2}[/tex]

x = [tex]\frac{41}{2} *\frac{4}{3}[/tex]

x = [tex]\frac{82}{3}[/tex]

Hence, the number is   [tex]\frac{82}{3}[/tex]  .

  B.  1.2×10^-3 mm

Step-by-step explanation:

What constitutes an "appropriate" unit depends on the use of the number. Since we're not told of any particular use, we might choose the smallest of the available units: mm.

  1.2×10^-3 mm

Additional comment

The most appropriate unit would be the one that eliminates the power-of-ten multiplier:

  = 1.2 µm

y=mx+b is the equation of a line, m is the slope (the rate of change).

Answer:-8j^2-16k

Step-by-step explanation:

First step:-2j^2-(-2)k=-2j^2+2k

Second step:

-6(j^2+3k) use the formula a(b+c)=ab + ac

a=-6 b=j^2 c=3k

-6j^2+(-6).3k

-6j^2-6.3k=-6j^2-18k because we multiplied 6x3=18

So we gather the whole equation And simplify

-2j^2+2k-6j^2-18k

-2j^2-6j^2 +2k-18k(add like terms)6+2=8

-8j^2+2k-18K (subtract Like terms 18-2=16)

And the answer will give -8j^2-16k

Answer: KJL, LJK and ∠J

Step-by-step explanation:

We have two rays.

JK and JL.

So the common point of bot rays is the point J.

In the angle notation, we usually write the common point in the middle.

So the possible notations for this angle are:

LJK or KJL.

Also knowing that the vertex of the angle is at the point J, we also could call this angle as:

∠J.

So the correct options are B, F and i suppose that the option D is actually ∠J (you wrote that the option D is only J)

Answer:

A program at a community college can be completed in no fewer than 8 months, but must be completed in less than 11 months.

Step-by-step explanation:

1. The closed dot means the number is equal to and the open dot means the number is less/ greater than

2. The line goes right from the 8 with a closed dot, making x greater than or equal to 8

3. The line goes left from the 11 with an open dot, making x less than ll

4. This means the number must be equal to or greater than 8, and less than 11

The situation that can be represented by the graph is this:

In the number line, numbers 8 to 11 are shaded. This is a range which can mean that the time duration for the completion of a college program cannot be lower that 8 months.

It can also be interpreted to mean that the time span cannot exceed 11 months. Therefore, option C is right.
