8w-15=57 two step equations
insens350 [35]

Answer:

w=9

Step-by-step explanation:

Our equation is: 8w-15=57

Add 15 to both sides

-15 is now gone because we added 15 so it would be zero

and we have 72 because 15 plus 57 is 72

Now we have:

8w=72

Divide by 8 on both sides

8w cancels out to just w

and 72 divided by 8 is 9

And you're left with:

w=9

Round number to nearest hundred 1,427 as 1,420. 68,136 as 68,130. 271,308 as 271,300. 7,593,656 as 7,594,000 right?
xenn [34]
Normally to round a number to the nearest hundred you want to go to the hundreds column for example:
1427
1...thousand, 4...hundred, 2...tenth, and 7... ones so this one would be 1400
68136=68100 and so on.... hope this helps

What is the area,in square centimeters,of a circle that has a circumference of 16 centimeters?
Ray Of Light [21]

Answer: 20.38\ cm^2

Step-by-step explanation:

We know that the circumference of a circle is given by :-

C=2\pi r, where r is the radius of the circle .

Given : Circumference of circle = 16 cm

Then, 16=2\pi r

i.e r=\dfrac{16}{2\pi}=\dfrac{8}{\pi}          (1)

We know that the area of circle is given by :-

A=\pi r^2

i.e. A=\pi (\dfrac{8}{\pi})^2                    [From (1)]

i.e. A=\pi (\dfrac{64}{\pi^2})

i.e. A=\dfrac{64}{\pi}

Put \pi=3.14

A=\dfrac{64}{3.14}=20.3821656051approx20.38\ cm^2

Hence, area of circle = 20.38\ cm^2
