Answer:
20 bracelets
Step-by-step explanation:
So Marcy has 12 bracelets and 15 necklaces. It is stated in the problem that this ratio (12:15) is the same as the ratio of Shelly's bracelets to necklaces (x:25). To solve this, we set up a proportion like so:
12/15=x/25 and we can use cross multiplication to solve for x. x=20, so the answer is 20 bracelets.

Answer:
60ft
Step-by-step explanation:
DC is 50% longer than BD (given)
BD is 40ft (given)
DC is 50% longer than BD this means that DC= BD+50% of BD
40ft +50/100 * 40
=40ft +20ft
=60ft
Another way to solve this could be DC is 150%of BD as BD =40ft=100% of it's length.
So, 150/100 *40
=60ft
