Answer:
Non Proportional
Step-by-step explanation:
Make a proportion:
For example say you want to test out how many bottles of water you can buy for $10
Proportion:
4 - 6
10 - ?
Solve: 10×6÷4=15
So technically, you could only get 15 bottles for $10. Therefore, this is a non proportional problem.
Combine like terms
11x^2 - y
Speed is 45 miles/1 hour.
135 miles x 1 hour/45 miles = 135/45=3 hours
