So, to set up this equation, lets just say that Lucas did 5 hours of homework also. The ratio of Lucas's homework to video games is 60 minutes of homework/30 minutes of video games. If we converted the 5 hours into 300 minutes then you would multiply the 60 minutes by 5 and the 30 minutes by 5 also. You would get 300 minutes/150 minutes. Jonathan's ratio is every 5 hours of homework/3 hours of video games. We would convert this to minutes by taking both numbers and multiplying them by 60. We would get 300 minutes/180 minutes. Using this we know that Jonathan gets more time to play video games because every 5 hours of homework he gets 180 minutes of gaming and for Lucas, every 5 hours of homework he only gets 150 minutes of gaming. I hope that this helped you!
Step-by-step explanation:
24÷(45÷25)= 21
x=21

Let's rewrite the system of equations:
y = three over four times x squared minus 3
y = (3/4) x ^ 2 - 3
y = negative three over four times x squared plus 3
y = (-3/4) x ^ 2 + 3
The system of equations is:
y = (3/4) x ^ 2 - 3
y = (-3/4) x ^ 2 + 3
The solutions are:
(-2, 0)
(2, 0)
