Answer:
about 70.0 mph
Step-by-step explanation:
speed = distance/time
(300 ft)/(2.92 s)·(1 mi)/(5280 ft)·(3600 s)/(1 h) = (300·3600/(2.92·5280)) mi/h
≈ 70.0498 mi/h
The Temperature at noon was 0° Because -8 + 8 = 0
What you can do is subtract 1x from each side
Then you subtract 3 from each side
Then it tells you x=2
Always put what you think x is back into the problem and see if it works out
Example on how you do it:
(x+5)=(2x+3)
5=(x+3)
2=x
Answer: 37 you just add the two in that case
