PLEASE HELP ME—————the ratio of red ribbons to yellow ribbons is 17:6 if the number of red ribbons is 2m+5 how many yellow ribbon are there?
Question
Answer:
The correct answer is 12/17m+30/17 yellow ribbons. Explanation:
Setting up a proportion to represent the ratio of red to yellow, we have
r/y = 17/6.
Cross multiply:
6r=17y.
To isolate y, cancel 17 by dividing:
6r/17 = y, or (6/17)r=y.
Substituting 2m+5 for r, we have
(6/17)(2m+5)=y.
Use the distributive property:
(6/17)*2m+(6/17)*5=y
(12/17)m+30/17=y.
