Write the expressions "Four times the difference of a number and 7 is 32", "One third of a number is 12 less than the number its

Anna71 [15]

Part 1) "Four times the difference of a number and $7$ is $32$ "

Let

x--------> the number

we know that

the expressions is equal to

$4(x-7)=32$

therefore

the answer part 1) is

$4(x-7)=32$

Part 2) "One third of a number is $12$ less than the number itself"

Let

x--------> the number

we know that

the expressions is equal to

$\frac{1}{3} x=(x-12 )$

therefore

the answer part 2) is

$\frac{1}{3} x=(x-12 )$

Part 3) "Ten increased by the quotient of a number and $2$ is $-15$ "

Let

x---------> the number

we know that

the expressions is equal to

$10+ (\frac{x}{2} )= -15$

therefore

the answer Part 3) is

$10+ (\frac{x}{2} )= -15$

Part 4) "One less than the product of a number and $3$ is $5$ more than the number itself"

Let

x---------> the number

we know that

the expressions is equal to

$(3x)-1=5+x$

therefore

the answer Part 4) is

$(3x)-1=5+x$

On the product by rounding to the nearest that NO LINKS

Svetlanka [38]

Arithmetic

To round, go to the length behind it.

2,413

If it is four or under, you keep the four and, you must turn everything to the left side to zero.

If it is five and up, turn the number into 3000.

Note: This cannot be rounded to 2,500 and 2,400 due to the question being asked.

Meaning, the equation formed is:

5x2,000=10,000

8(2x-3)-6x if 3=x and simplify

Rom4ik [11]

Simplify the expression:

8(2x - 3) - 6x = 8×2x - 8×3 - 6x = 16x - 24 - 6x = 10x - 24

for x=3

put value of "x" to the expression:

10×3 - 24 = 30 - 24 = 6

The Han dynasty lasted from 206 B.C. to 9 A.D. How many years did the dynasty last?

cricket20 [7]

Answer:

The Han dynasty last was, 215 years

Step-by-step explanation:

Given statement: The Han dynasty lasted from 206 B.C. to 9 A.D.

To find how many years did the dynasty last.

B.C. represents Before Christ

A.D. represents After Death

To find the difference between two dates,

When the endings are the same you subtract

When they are different you add

You can see that the endings in the given 206 B.C. and 9 A.D. are B.C. and A.D. are different.

Just add these 206 and 9 we get;

$206 + 9 = 215$ years

Therefore, 215 years did the Han dynasty last.

Pls help n hurry i will give brainliest

AlekseyPX

Answer: A) and B)

Step-by-step explanation:

So for the first one, a closed circle means that it includes the point and the graph proceeds in the positive direction. So it will be whatever number it starts on in the x axis is less than or equal to x.

The second one you find the distance it moves each second.

You do this by distance over time d/t. Then you divide the 408 by that number.

So 264cm / 11 seconds = 24 cm/sec

Then 408cm/ 24cm per sec = 17s
