Answer: -48

Step-by-step explanation: You will add the 4 to each side of the equation, making the 4 on the left side cancel and on the right side when you add The 4, you are actually subtracting because anytime you have a negative and a positive you will subtract and take the sign of the larger number. That will leave you with x/3=-16. Multiply everything by 3 to get rid of the fraction and that will leave you with x=-48

siniylev [52]

Answer:

Step 2: 20x = 80 + 10x

Step-by-step explanation:

Step 1: 20x - 10 = 80 + 10x

Add 10 to each side

20x - 10+10 = 80+10 + 10x

20x = 90 + 10x

Step 2: 20x = 80 + 10x This has the first error

Step 3: 10x = 80

Step 4: x= 8

A circle circumference is 600 M. what is the good approximation of the circle area

wlad13 [49]

Answer:

The area of the circle is 28662 M².

Step-by-step explanation:

Given:

Circumference of circle = 600 M.

Now, to find the area of the circle.

So, <em>to get the area we need to find the radius.</em>

By putting the formula of circumference we get the radius:

Let the radius be r.

Circumference = 2πr

$600 = 2\times 3.14\times r$ (taking the value of π = 3.14.)

$600=6.28r$

Dividing both sides by 6.28 we get:

$95.54=r$

Now, <em>for getting the area we put the formula:</em>

Area = πr²

$Area = 3.14\times 95.54^{2}$

$Area = 3.14\times 9127.89$

$Area = 28661.57$

So, <u><em>approximately the area of the circle = 28662 M²</em></u>.

Therefore, the area of the circle is 28662 M².
