Let the sisters have dollars in the amounts of a,b,c.
<span>After the youngest splits half of hers with the others, they have </span>
<span>a/2, b+a/4, c+a/4 </span>
<span>After the middle gives each of the others 4, they have </span>
<span>a/2 + 4, b+a/4 - 8, c+a/4 + 4 </span>
<span>After the eldest splits half of hers with the others, they have </span>
<span>a/2 + 4 + (c+a/4 + 4)/4, b+a/4 - 8 + (c+a/4 + 4)/4, (c+a/4 + 4)/2 </span>
<span>Now they all have 16. </span>
<span>a/2 + 4 + (c+a/4 + 4)/4 = 16 </span>
<span>b+a/4 - 8 + (c+a/4 + 4)/4 = 16 </span>
<span>(c+a/4 + 4)/2 = 16 </span>
<span>substituting in the last expression, we have </span>
<span>a/2 + 4 + 8 = 16 </span>
<span>b + a/4 - 8 + 8 = 16 </span>
<span>c/2 + a/8 + 2 = 16 </span>
<span>a = 8 </span>
<span>b = 14 </span>
<span>c = 26</span>
It’s either 64 or 192 if that helps because it say she buys a three week ad would u times 64 by three I’m sorry I don’t have a final answer
The diameter is 18 so in exact terms the circumference would be 18 pi but if you were to get an estimate of the circumference you would multiply the diameter, 18, by 3.14 and get an answer of 56.52. So the circumference in exact terms is 18 pi or estimated to be 56.52 in.
where you write down a number this way:
In this example, 5326.6 is written as <span>5.3266 × 103</span>,
because 5326.6 = 5.3266 × 1000 = 5.3266 × 103
