I believe its 27.75. I wouldn't take my word for it though.
40; base it off of the y-intercept [C]. What is the unit of measurement?
Not unless the digits in each period are also in the same order. That is, the digit in each PLACE must be the same.
Answer:
y = 6.5
Step-by-step explanation:
<span>distance=6390km; time=9 hrs; rate=710kph
With the wind Data:
distance=5150km; time=5hrs; rate=1030kph
EQUATIONS:
airspeed+jetstream=1030
airspeed-jetstream=710
Subtract these equations to get:
2jetstream=320kph
jetstream=160mph </span>
