Answer:
138
Step-by-step explanation:
We know that there are at least 3 short sleeved shirts and there are at least 7 long sleeved shirts. And we know it's in that ratio. So the best way to start this is to divide 460 by 7+3 to get the single unit amount of both shirts.
46 is the single unit amount. So 46 * 3 will get us our short sleeved shirts:
46 * 3 = 138
To check our answer, we'll take 460-138 and divide that by 7 to see if we get 46:
322/7 = 46
So the answer is correct!
![(30a^2-11a+15)(5a-6)^{-1}= (30a^2-11a+15)/(5a-6)\(5a-6)(6a+5)/(5a-6)\6a+5](https://tex.z-dn.net/?f=%2830a%5E2-11a%2B15%29%285a-6%29%5E%7B-1%7D%3D%20%2830a%5E2-11a%2B15%29%2F%285a-6%29%5C%285a-6%29%286a%2B5%29%2F%285a-6%29%5C6a%2B5)
The final simplified answer is 6a + 5.
