8 less than twice a number is 10. What is the number?

Answers

Answer 1

Answer:

Answer:9

Step-by-step explanation: This can be represented by the equation

2n(twice a number) - 8(8 less than) =(is) 10

or 2n-8=10.

Adding 8 to both sides, we get

2n=18

so n=9

Hope this helped!!

Answer 2

Answer:

Answer:

Step-by-step explanation:

2X-8=10

2X=10+8

2X=18

X=18/2

X=9

THEREFORE, THE NUMBER IS 9.............................

Polygon ABCD is plotted on a coordinate plane.If the polygon translates 3 units to the left and 1 unit down,the length of diagonal A’C’ is __ units ( 2,3or 6) if the polygon translates 3 units further to the left and four units down, the length of diagonal A’C’ ( increases,decreases or remains the same

Answers

Length of diagonal A'C' will be 2 units and it will remain the same even after multiple translations.

Length of a segment joining two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by the expression,

Length between two points = $√((x_2-x_1)^2+(y_2-y_1)^2)$

Therefore, length of diagonal AC joining points A(3, 4) and C(3, 2) will be,

AC = $√((3-3)^2+(4-2)^2)$

= 2 units

If the polygon ABCD is shifted left, right, up and down, translations done will be the rigid transformations showing no change in shape and size of the polygon.

Therefore, length of diagonal A'C' will be 2 units and it will remain the same when the polygon is translated.

The length of the diagonal will be 2.

When a translation is performed on a shaped, it simply moves location. The size and shape of the object do not change. Therefore, the length of AC will remain the same at all times.

Herman horse trader bought a horse for $600 and then sold it for $700. The next day he bought it back for $800 and then sold it for $900. How much money did Herman make altogether?

Answers

The total amount of the profit will be $200.

What is a profit?

A monetary profit, particularly the distinction between the amount gained and the actual cost of purchasing, running, or creating anything.

The profit is given as,

Profit = Selling price - Cost price

Herman horse trader bought a horse for $600 and then sold it for $700.

Then the profit will be

⇒ $700 - $600

⇒ $100

The next day he bought it back for $800 and then sold it for $900.

Then the profit will be

⇒ $900 - $800

⇒ $100

Then the total amount of the profit will be

P = $100 + $100
