A+7=0
A+7-7=0-7
A=-7
B+3=7
B+3-3=7-3
B=4
Answer:
y=32x-32
Step-by-step explanation:
this time no algorithm or equation was needed i saw that if the equation was y=32x there would be ordered pairs (1,32) and (2,64) so to delay it by 1 on the x side just subtract the slope from the y - intercept sorry if that doesn't make sense
So 1 hour = 60 minutes, you do 60 + 37 and you get 97, Vincent has watched 52 minutes of the movie, so you subtract 97 by 52 and you get 45, hope this helped. It will appreciated if you give me a star so I can help even more people that are having trouble :)
Step-by-step explanation:
THE DIVISION of the hour into 60 minutes and of the minute into 60 seconds comes from the Babylonians who used a sexagesimal (counting in 60s) system for mathematics and astronomy. They derived their number system from the Sumerians who were using it as early as 3500 BC.
Remark
Average in this case does not mean you take (s1 + s2)/2. What average speed means is Total Distance / Total Time.
Formula
Average speed(s) = Total Distance / Total Time
Givens
Total Distance = 252 + 30 = 282 miles
Total Time = 5 hours.
Substitute and Solve
Average speed = 282 / 5
Average speed = 56.4 miles / hour <<<<< Answer.
The other facts are not used.
