Answer:

EVERYONE IT IS 3/4 lol

Step-by-step explanation:

The difference of the expression (-3 + 1/2) - (-4 + 1/4) is 3/4.

Additive inverse in simple terms is meant to add a number with it's opposite sign to get the result as zero.

Mathematically for any number 'a', a + (-a) = 0 implies that -a is the additive inverse of 'a'.

The given expression is, (-3 + 1/2) - (-4 + 1/4).

(-3 + 1/2) - (-4 + 1/4) = [(-3 × 2 + 1) / 2] - [(-4 × 4 + 1) / 4]

                               = (-7/2) - (-17/4)

The additive inverse of (-7/2) is (+7/2).

Adding and subtracting the additive inverse (+7/2),

(-3 + 1/2) - (-4 + 1/4) = (-7/2) - (-17/4) + (7/2) - (7/2)

                               =  (-7/2) + (17/4) + (7/2) - (7/2)

                               = [(-7/2) - (7/2)] + [(17/4) + (7/2)]

                               = (-14/2) + (31/4)

                               = (-28/4) + (31/4)

                               = 3/4

Hence the difference of the expression given is 3/4.

Answer:

5n-10 < 6n-8

n - is the variable that's stands for the unspecified number

step 1. ten is less than 5 times a number

step 2. LESS THAN SIGN :)

step 3. six times the number decreased by 8

......................

oh and if you're looking to simplify that problem I believe it would be worked out like this....5n-10<6n-8....subtract 5 from both sides....-10

Answer:

90°

Step-by-step explanation:

The clock face is a circle and represents 360°

There are 12 divisions 1- 2- 3- 4 - 5 - 6 - 7 - 8 - 9 - 10- 11 - 12 on the face

Each division = 360° ÷ 12 = 30°

There are 3 divisions between 4 and 7 , thus

arc measure = 3 × 30° = 90°

Answer:

90°

Step-by-step explanation:

We see that the slope intercept is y = 8x - 20. So if we substitute x with 2, because x represents the amount of necklaces sold and we are analyzing her net profit after selling 2 necklaces, that gives us y = 8(2) - 20. Which simplifies to y = -4. So by the time Jocelyn sells 2 necklaces, her net profit will be at -4.

Answer: CE= 8

Step-by-step explanation:

Answer:

6x^2 + 2x - 5 (Option C)

Step-by-step explanation:

1. First, add 4x^2 and 2x^2 together (which is 6x^2). You can figure this out by adding 4 and 2.

2. Second, add -5x and 7x (which is 2x)

3. Lastly, subtract 3 and 8, which is -5

WHY DOES THE ANSWER HAVE A NEGATIVE 5?

The equation looks like this: +3 + -8

You are adding 3 to -8, which is the same as subtracting positive 3 and positive 8 (positive times a negative is a negative or a minus sign)

Answer:

C. 6x^2 + 2x - 5

Step-by-step explanation:

4x^2 + 2x^2 = 6x^2

-5x + 7x = 2x

3 - 8 = -5

Therefore,

4x^2-5x+3 + 2x^2+7x-8 = 6x^2+2x-5

Answer:

D.441

Step-by-step explanation:

All sides of a square are equal. Due to this, the perimeter can be expressed as 4 times the side of the square. Let x be the side of a square.

Then we have:

4x = 84

x = 21

The area of a square is written as x^2, as x is both the length and the width.

So your answer will be:

(21)^2 = 441

The area of the garden is  441 sq ft

A square is a quadrilateral with four equal sides.

Characteristics of a square includes:

• The diagonals bisect each other at 90°.

• Opposite sides parallel and of equal length

• The four angles of a square are equal.

Perimeter of a square =4 x length

84 = 4 x length

divide both sides of the equation by 4

84/4 = length

length = 21 feet

Area of a square = length²

21² =  441 sq ft

Hey,

Solution,

Marked price(MP)= $ 80

Discount percent= 20%

Now,

Discount amount=discount percent of MP

= 20% of 80

=20/100*80

= $ 16

Again,

Selling price(SP)=MP - Discount amount

=$80 -$16

=$64

So,the sale price of the CD player is $ 64.

Hope it helps...

Good luck on your assignment....

C) A quadrilateral with four congruent sides and four right angles is a square.

The  P ↔ Q represents A quadrilateral with four congruent sides and four right angles is a square.

A closed quadrilateral has four sides, four vertices, and four angles. It is a form of polygon. In order to create it, four non-collinear points are joined. Quadrilaterals always have a total internal angle of 360 degrees.

Given:

If a quadrilateral has four congruent angles, then it's a rectangle.

the statement cannot be true because the same property also carried by Square.

If a quadrilateral has four congruent sides, then it's either a square or a rhombus but reverse is not possible.

A quadrilateral with four congruent sides and four right angles is a square.
