0.78 because 21.06 divided by 9 is 2.34 and divide by three because you have to make three sculptures so you get 0.78 :)
<span>Okay. Well it's C. 1/2 hour is 30 mins, so 30 times 3 is 90. Just as the answer states, 90 water balloons filled after 1/2 of an hour. </span>
So the width can be written as W=3L-6. (L is length and W is width). The maximum the width could be is 45mm, so try to use 45mm in place of W. 45=3L-6. Add 6 to both sides and you get 51=3L. Divide both sides by 3 and you get 17=L, where L is the length.
