C = 2 pi r
but c = 15
15 = 2 pi r
15 = 2 * (22/7) * r
r = (15*7) / 2 / 22
r = 2.386
2x-4=49
2x=54
x is equal to 27
Since in this equation we are dividing 17/2 by 1/4, we can think of this as multiplying 17/2 with 4/1 (or 4).
17 4
---- X ----- = 34
2 1
Our final answer is 34 days.
The answer is C
5.76 x 10 ^3 means you move the decimal 3 times:
57.6> 576.0> 5760
9x24=216
So your answer is 24
