Look at it like this, let's say that with this 4x, x = 10. This means.. 4x = 4(10) = 40. right? okay. so.. what if we divide this 40 by 4? kind of like the fraction I wrote to the top-left. what would we get, and what do we notice? (keep in mind what I said in the beginning of this message. this an example that demonstrated why 4x ÷ 4 = x

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.

your answer is b.

x = 33.9

y = 65.6
