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: C
<u>Step-by-step explanation:</u>
A) not completely factored because 2 can be factored out of 2x + 4
B) not completely factored because 3 can be factored out of 3x - 9
C) CORRECT
D) not factors because the terms are added instead of multiplied
Figure out the length of the rectangle by using the diameter of the 2 circles added together then work out the width by using the diameter of one circle (since the vertical diameter will be the same length as the width if that makes sense)
