Answer:
D
Step-by-step explanation:
4.10pm-1.55pm
=3.70pm-1.55pm

We can convert 20km to 20,000m. Then, we can subtract 800m (walking distance) from 20,000m which would result in 19,200m. Then we can put 19,200m and 20,000m as a fraction (19200/20000). Before we can multiply it by 100 to make it in the percentage form, we can get rid of 2 zeroes for both number making it 192/200 and then further simplifying it to 24/25 by dividing both numbers by 8. Finally to get the percentage we can multiply 24 and 100 (2400) and then divide the result (2400) by 25. The final answer is 2400/25=96 meaning he cycled 96% of the journey and walked 4% of the journey (100-96=4).
Answer:
x1 = -1, x2 = 2, x3 = -4, x4 = 0
If it wants everything in terms of what x4 equals then the system is inconsistent since x4=0
Step-by-step explanation:
Once you have it in that reduced row echelon form it's super easy.
The first column is x1, second is x2 and so on.
The first row says x1 + 0x2 + 0x3 + 0x4 = -1, or in other words x1 = -1. You can do this for all the rows.
this does mean that x4 = 0, so if the instructions are saying it wants everything n terms of x4, you can't do that so it is inconsistent.
