One-forth of r can be written as,
r/4.
Now, r/4 is subtracted from 10 and this is greater than 5.
Therefore, inequality is,
10 - r/4 > 5
That is 1/64 is what it is
Answer:
a) 9 ways.
b) 6 ways.
Step-by-step explanation:
We know that there are three different routes connecting city A to city B.
We calclulate how many ways can a round trip be made from A to B and back. We conclude that the exists 3·3 = 9 ways.
We calclulate how many ways can a trip be made from A to B if it is desired to take a different route on the way back. We conclude that the exists
3·2 = 6 ways.
