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
-
+ 6
divide each term on the numerator by 7b
= - 7
/ 7b + 42
/ 7b
= -
+ 6
M-(M x 0.16) and M-(.84) because the first one you need to multiply to find what 16% of m is then subtract that by m for the second one you subtract.
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?

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
Answer: 
Step-by-step explanation:
We know that the circumference of a circle is given by :-
, where r is the radius of the circle .
Given : Circumference of circle = 16 cm
Then, 
i.e
(1)
We know that the area of circle is given by :-

i.e.
[From (1)]
i.e.
i.e.
Put 
Hence, area of circle =
