Which system of equations can be used to determine the price of a plant, p, and the price of a bush, b? 7p+8b=3909p+6b=400 9p+6b=3907p+8b=400 7p+9b=3906p+8b=400 9p+8b=3907p+6b=400

OK, here you go.. this is the correct answer. Hope this helps!(very helpful for k12 students)

Step-by-step explanation:

9p+6b=390

7p+8b=400

those are the answers bolded

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
