Answer
Find out the what fraction of the sandcastle did they build together .
To prove
Let us assume that the fraction of the sandcastle they build together be x .
As given


Than the equation becomes

L.C .M of (3,7) = 21
solving


Therefore the fraction of the sandcastle did they build together be

Hence proved

Answer:
C. y=1/2x-6
Step-by-step explanation:
The correct answer is C. y=1/2x-6.
If we are finding 1/2 of the length, and the length is represented by x, than we would have 1/2x.
It also says 6 less than halve of the length, so we would represent that as 1/2x-6, and that shows us the proper equation to find the width.
Hope this helps!
