Lets find the unit rate of both of the shirts.
5 for 63
4 for 54
63/5 = 12.60
54/4 = 13.50
Now we have our unit rates!
Greg = $12.60 per shirt
Zachary = $13.50 per shirt
Greg's shirt were cheaper than his brothers, so it has a better cost.
So the total number of movie tickets sold was 1200. This means that a + c = 1200 because a represents the number of adult tickets purchased and c represents the number of child tickets purchased. The total money they made off the movie was $6400. This means 7 multiplied by the number of adult tickets would result in the total they earned off adult tickets, and 3 multiplied by the number of child tickets would result in the total they earned off child tickets. This total equals 6400. So 7a + 3c = 6400. These are our two equations: a + c = 1200 and 7a + 3c = 6400. The answer choice that matches this is choice A, so your answer is A. Hope this helps. Feel free to ask more questions, or ask more questions about my explanation.
The answer should be 12 inches

Answer:
? = 15a^2
Step-by-step explanation:
We assume you want
(5a)/(8ab) = (?)/(24a^2·b)
Multiplying by 24a^2·b, we get ...
(5a)/(8ab)·(24a^2·b) = ? = 15a^2
