how many solutions does the equation 8x+16=8x-16 have?

The relation between multiplying and dividing two negative fractions is needed.

When multiplying and dividing two negative fractions the answer will be always positive.

Let [tex]-\dfrac{a}{b}[/tex] be one fraction

and [tex]-\dfrac{c}{d}[/tex] be another fraction

Let us multiply them

[tex]-\dfrac{a}{b}\times -\dfrac{c}{d}=+\dfrac{ac}{bd}[/tex]

Let us divide them

[tex]\dfrac{-\dfrac{a}{b}}{-\dfrac{c}{d}}[/tex]

This can also be written as

[tex]-\dfrac{a}{b}\times -\dfrac{d}{c}=+\dfrac{ad}{bc}[/tex]

Since, multiplication and division are the inverse of each other the negative signs cancel each other and the sign is positive.

Hence, when multiplying and dividing two negative fractions the answer will be always positive.

Answer:

Step-by-step explanation:Simplifying

3x + 8 = 2x + -21

Reorder the terms:

8 + 3x = 2x + -21

Reorder the terms:

8 + 3x = -21 + 2x

Solving

8 + 3x = -21 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

8 + 3x + -2x = -21 + 2x + -2x

Combine like terms: 3x + -2x = 1x

8 + 1x = -21 + 2x + -2x

Combine like terms: 2x + -2x = 0

8 + 1x = -21 + 0

8 + 1x = -21

Add '-8' to each side of the equation.

8 + -8 + 1x = -21 + -8

Combine like terms: 8 + -8 = 0

0 + 1x = -21 + -8

1x = -21 + -8

Combine like terms: -21 + -8 = -29

1x = -29

Divide each side by '1'.

x = -29

Simplifying

x = -29

3x + 8 = 2x + 21

3x - 2x + 8 = 21

x + 8 = 21

x = 21 - 8

x = 13

D) 5/6 as 5/6 = 0.833333333333333 and the three will keep repeating

Answer:

D.

Step-by-step explanation:

You meant which one is a repeating decimal.

Okay to find out you would have to divide each.

4 divided by 5 = 0.8

1 divided by 2 = 0.5

3 divided by 4 = 0.75

5 divided by 6 = 0.833333333...

See how the three keeps on repeating? That makes it a repeating decimal.

Answer:

[tex]\angle AFY=140^\circ[/tex]

[tex]\angle LIM=117^\circ[/tex]

Step-by-step explanation:

The sum of interior angles of a polygon of n sides is:

[tex]S=180^\circ (n-2)[/tex]

The image shows a 6-side polygon. The sum of the interior angles is:

[tex]S=180^\circ (6-2)=720^\circ[/tex]

The sum of all the shown interior angles must equal 900°:

[tex]125+100+y+117+121+y+23=720[/tex]

Simplifying:

[tex]486+2y=720[/tex]

Solving:

[tex]2y=720-486[/tex]

[tex]2y=234[/tex]

[tex]y=234 / 2=117[/tex]

y=117°

Thus the angle AFY is:

[tex]\angle AFY=y+23=117+23=140[/tex]

[tex]\boxed{\angle AFY=140^\circ}[/tex]

[tex]\angle LIM=y=117[/tex]

[tex]\boxed{\angle LIM=117^\circ}[/tex]
