Answer:
in standard form: 641000000
in scientific form: 6.41 * 10^8
Step-by-step explanation:
hi again :)
first, make each term into standard form: (6.7 * 10^8) = 670000000 and (2.9 * 10^7) = 29000000
670000000 - 29000000 = 641000000
in scientific notation: 641000000 = 6.41 * 10^8
hope this helps! <3
8*5=40
4*10=40
so the least number of hot dogs you can buy so that you can also buy a matching number of buns is 40.
Answer:
First, Divide both sides by -1,
Then Subtract 4 from both sides,
Answer:
12.5 hours
Step-by-step explanation:
The function d(x) = 1375 -110x represents the distance in miles a high-speed train is from its destination after x hours of travel.
So, when the train reaches its destination then d(x) will become zero miles.
Therefore, 0 = 1375 - 110x
⇒ x = 12.5 hours.
So, the train will travel 12.5 hours to reach its destination. ( Answer )
OD) x =-2 + 215, = -2 - 2 15
