is x²-x divisible by 2?​

Answers

Answer 1

Answer:

Yes

Step-by-step explanation:

There are two cases: Case 1: x is even, so x can be modelled as a generic number 2n, where n is a positive integer. Clearly this product is divisible by two. ... Hence, it is safe to generalise that the term x²-x is divisible by 2 for any positive integer x.

Answer 2

Answer:

Step-by-step explanation:

No, because [tex](x^2-x)/2[/tex] does equal [tex]x^2/2-x/2[/tex]. Honestly, it really depends on the value of x, as it provide whether or not the expression is divisible by 2.

the biggest number possible is 888,888 because 8 is the largest number and the question doesn't say that you have to use each number

200,000 is the smallest number because outside 0, 2 is the second-smallest number, and since 000,000 isn't a number 200,000 is the next best thing

lines a and b are parallel m∠4=

Answers

The angle 4 and 120 degrees angles are alternate angles. Therefore, ∠4 = 120 degrees.

What is an alternate angle?

Alternate interior angles are the angles formed when a transversal intersects two parallel lines.

Alternate interior angles are the angles formed on the opposite sides of the transversal.

Alternate interior angles are congruent.

Therefore,

∠4 is an alternate interior angle to angle 120 degrees.

Therefore,

∠4 = 120 degrees.

A)

[tex] \frac{x + 6}{3} = 10 \\ x + 6 = 10 \: . \: 3 \\ x + 6 = 30 \\ x = 30 - 6 \\ x = 24[/tex]

B)

C)

[tex]6x - (15 + 4x) = 35 \\ 6x - 15 - 4x = 35 \\ 2x = 35 + 15 \\ 2x = 50 \\ x = \frac{50}{2} \\ x = 25[/tex]

D)

[tex] \frac{3x}{5} = 15 \\ 3x = 15 \: . \: 5 \\ 3x = 75 \\ x = \frac{75}{3} \\ x = 25[/tex]

The scale of drawing is 1 inch : 27 inch

What is scale factor?

The scale factor is a measure for similar figures, who look the same but have different scales or measures. The scale factor states the scale by which a figure is bigger or smaller than the original figure.

Given that, the measurement of the tile = 27/4 inches

Side of the drawing = 1/4 inches

The scale of the drawing =

1/4 inch of drawing = 27/4 inch of tile

That means, 1 inch of the drawing = 27 inch of the tile

Therefore,

The scale of the drawing is 1 inch : 27 inch

Brittany bought 3 bracelets and 2 necklaces for $21. Each bracelet cost $5. The necklaces were all the same price. What is the cost for 1 necklace?

Answers

Answer:

The cost for 1 necklace is $3.

Step-by-step explanation:

With the information provided, you can say that the amount spent in bracelets and necklaces is equal to the price per bracelet for the number of bracelets plus the price per necklace for the number of necklaces, which is:

c=3x+2y, where:

c is the total cost

x is the price per bracelet

y is the price per necklace

Now, you can say that c=21 and x=5 and solve for y to find the price per necklace:

21=(3*5)+2y

21=15+2y

21-15=2y

6=2y

y=6/2

y=3

According to this, the answer is that the cost for 1 necklace is $3.

For every 21 books Ethan read, Sadie read 9 books.

Unsimplified Ratio = 21:9

21 and 9 have a common factor of 3.

Because 21 and 9 share a common factor we can simplify the ratio

21 / 3 = 7

9 / 3 = 3

The new ratio is 7 to 3

So for every 7 books Ethan read, Sadie read 3 books.
