Step-by-step explanation:

Given parameters:

Fraction given to charity = [tex]\frac{1}{3}[/tex]

Fraction given to wife = [tex]\frac{2}{3}[/tex]

Unknown:

Fraction given to son and daughter =?

Solution:

Let the total property  = x

    Fraction given to charity  = [tex]\frac{1}{3} x[/tex]

    Fraction given to wife  = [tex]\frac{2}{3} x[/tex]

The remaining was given to son and daughter = F

    So;

     Total property  = fraction given to charity + fraction given to wife + fraction given to son and daughter

         x  = [tex]\frac{1}{3} x + \frac{2}{3} x + F[/tex]

            F = x - ([tex]\frac{1}{3} x + \frac{2}{3} x[/tex])

            F = 0

The son and daughter will not inherit anything

Answer:

The Inequality n+8>11

n>3

Step-by-step explanation:

The inequality for the given phrase is n+8>11 and its solution is n∈(-∞,3).

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.

The given phrase "A number n plus 8 is greater than 11" can be written in the form of inequality as shown below.

Now, the inequality can be solved for the value of n as shown below,

n + 8 > 11

Subtract 8 from both sides of the inequality,

n + 8 - 8 > 11 - 8

n > 3

Hence, the inequality for the given phrase is n+8>11 and its solution is n∈(-∞,3).

Answer:

-3

Step-by-step explanation:

The additive inverse of a number means that the sum of the number, and it's additive inverse will always be zero. The additive inverse is found by simply negating a number or making it opposite.

Therefore, 3 + x = 0, 3 - 3 + x = 0 - 3, x = -3. (x represents it's additive inverse)

Just keep in mind that finding it's additive inverse is usually the best way to do it.

Here are some ways to negate a number:

Answer:

Step-by-step explanation:

2x-8 ≤ 14

1. Add 8 to both sides of the inequality sign to move the 8 from the left side to the right side.

2x ≤ 22

2. Divide both sides by 2 to get the x alone.

x ≤ 11

3. Make a number line from 8 to 13 (numbers can be changed), draw a circle above the number 11 and fill in the circle.

4. Now, make a line going from the circle to the left and draw an arrow at the end.

Answer:

the degree of f(x) is 3

Step-by-step explanation:

fundamental theorem of algebra

The degree of function f(x) is at least 3.

The function has n intercepts i.e. it touches the x-axis n times, then the function will have at least n roots.

And as we know if the degree of the function is n then the number of roots of the function is n.

So, if the function has n intercepts, then the function has at least n degrees.

Here given that the polynomial function f(x) has 3 intercepts.

Then from above, it is clear that the function will have at least 3 roots.

And the function will have at least 3 degrees.

Therefore If the polynomial f(x) has 3 intercepts, then The degree of function f(x) is at least 3.

Answer:

$5

Step-by-step explanation:

if you want the cost of 1 pair of colored socks, substitute that into c

5(1) + 3w = 32

5 + 3w = 32

subtract on both sides

3w = 27

this means the amount of pairs of white socks is 9.

multiply by 3

$27

then subtract by 32

$5

he only bought 1 pair of colored socks for $5

10) These angles are vertical angles.

Whenever two lines intersect, vertical angles are always formed.

Vertical angles are always congruent so we know that b = 43°.

1) Notice that there is a box at the vertex of <EBF.

This tells us that it measures exactly 90 degrees.

Also note that <ABC is a straight angle which means its 180 degrees.

So we have x + 10 + 90 + 2x + x = 180.

First simplify the left to get 4x + 100 = 180.

Solving from here, we find that x = 20.

2) Notice that <AEC and <DEB are vertical angles.

Vertical angles are congruent so we

can setup the equation 3x + 18 = 5x + 6.

First subtract 3x from both sides to get 18 = 2x + 6.

Now subtract 6 from both sides to get 12 = 2x.

Solving from here, we have x = 6.

Answer:

I believe its 8.8.

Step-by-step explanation:

What I did was divide 53 by 6.

Answer:

5,8

Step-by-step explanation:

A point (-5,8) rotated around the origin 270 degrees counterclockwise will have coordinates (-8, -5).

Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.

Dilation: The preimage is scaled up or down to create the image.

Reflection: The picture is a preimage that has been reversed.

Rotation: Around a given point, the preimage is rotated to create the final image.

Translation: The image is translated and moved a fixed amount from the preimage.

We know when we rotate a point counter-clockwise the coordinates (x, y) becomes (-y, x).

Given, A point (-5,8) around the origin 270 degrees counterclockwise.

∴ The new coordinates of the points will be (-8, -5).

Answer:

The distance would be 6.7 or 3✓5

Step-by-step explanation:

Im sure there's a faster way to find this, but I'm in 8th grade sooo yeah.

First things first we can use the equation

d=✓(X2-X1)*2+(Y2-Y1)*2

X2= 8

X1= 5

Y2= 13

Y1= 7

From here, you plug in the values and do as followed. You subtract the values to get the answer. For example 8-5 would get us (3)*2.

From here you square the 3 to get 9. You also do the same to the right side of the equation.

Now you have d=✓(3)*2 + (6)*2

From here you square it and you get d=✓9+36

Now we have: d✓45

Now we square the 45 to get 6.7082..., but we round the answer to get 6.7!
