23. 3/5
24. 0
Step-by-step explanation:
turn the 1 into a fraction for each of the problems.
for 22. it would be 8/8 because also trying to make the denominators the same.
8/8 - 5/8 = 3/8

Answer:
One solution
Step-by-step explanation:
The blue line is a tangent line to the parabola, and because tangent lines only touch another line at one point, there must only be one solution to the system of equations.
Answer: 52,416,000 km
Step-by-step explanation:
If a comet travels 273,000 km/hr
1) Multiply 273,000 km by 24 hours to find how far the comet travels in one day
2) multiply the answer from 1 by 8 to determine how far it travels in 8 days
1) 
*
= 
(hours cancel out)
2)*8 day= 52,416,000 km in 8 days
The comet approximately travelled 52,416,000km from when it began to travel to when it reached Earth. Hope this helped :)
You can break down the equation like this - (using Pemdas) 14 x 18 = 252 then you add 29 which equals 281.
Hope that helped!!
