Answer:
Distance between the national parks is 275 miles.
Step-by-step explanation:
We have given,
Average speed of train = 55 miles per hour
Total time taken = 5 hours
We need to find the distance between the national park.
i.e Distance = Average speed × time taken
Distance = 55 × 5
Distance = 275 miles
Hence the distance between the national parks is 275 miles.
The answer to the problem are -3 and -8 because the two equation are being solved for 0
Measurement of one angle and length of one side I think
4x=20-8y
x=5-2y now use this value of x in the second equation...
3(5-2y)+6y=15
15-6y+6y=15
15=15 This is true for any y or x value.
So there are infinitely many solutions as the two equations describe the same line.
