Step-by-step explanation:
The rate of production is 540 per 0.5hr=>1080 per hour.
Let t be the number of hours. We convert the times in hours only(1 hr=60mins)
- 3hrs 30 mins=3.5hrs
- 5hrs 15mins=5.25hrs
- 8grs 45 mins=8.75hrs
#We therefore multiply directly to find the number of cups after t hours:
![C_{3.5h}=1080\times 3.5\\\\=3780 \ cups\\\\C_{5.25hr}=1080\times5.25\\\\=5670\ cups\\\\C_{8.75hr}=1080\times 8.75\\\\=9450\ cups](https://tex.z-dn.net/?f=C_%7B3.5h%7D%3D1080%5Ctimes%203.5%5C%5C%5C%5C%3D3780%20%5C%20cups%5C%5C%5C%5CC_%7B5.25hr%7D%3D1080%5Ctimes5.25%5C%5C%5C%5C%3D5670%5C%20cups%5C%5C%5C%5CC_%7B8.75hr%7D%3D1080%5Ctimes%208.75%5C%5C%5C%5C%3D9450%5C%20cups)
Answer:
x = 3
Step-by-step explanation:
3=5x-12
Rearrange the Equation.
5x - 12 = 3
Add 12 to both sides.
5x - 12 + 12 = 3 + 12
Simplify
5x = 15
Divide both sides by 5
5x/5 = 15/5
x = 3
Answer: 11
= 10.67707825
rounded to nearest whole number would be 11
