Answer:
Step-by-step explanation:
1. regroup terms
2. Rewrite 
as 
and 343 as 
3. Since both terms are perfect cubes, factor using the sum of cubes formula, 
, where 
and 
4. Factor 
out of 
5. Regroup
6. Factor again
Y is already solved because y=kt
Ok so the ratio is ... 5/12 (every 5 months out of 12 in on year, the main dish is on the cover)
All you have to do is multiply the top # and bottom # in the fraction by 5.
5*5 = 25
5*12 = 60
In 5 years, there are 60 months. During that time, a main dish will be on the cover 25 times.

Answer:
16 in.
Step-by-step explanation:
We have the ratio
How about let's make this easier. Easier is better, right? Let's get rid of the fraction 2/3. We will do that by multiplying 2/3 by 3 and 1 by 3 to get the equivalent ratio of
Now we need to know how many inches there would be if the number of feet is 24:
Cross multiply to get
3x = 48 so
x = 16 in.
