Answer:
Given,
The total distance covered = 4 km,
Since, initially he would be in rest,
So, his starting point would be 0.
Now, his first break =
km,
Second break =
km,
Also, we can write,

Drawing number line:
Step 1: Draw a line.
Step 2: Make 12 marks in same distance.
Step 3: Starts from 0, then 1/3, 2/3, 3/3 and so on.
Thus, we can show Wayne's bike on a number line as below.
Answer:
7/10 or 70%.
Step-by-step explanation:
There is a total of 20 marbles in the bag.
There are 10 + 4 = 14 marbles which are not blue.
The required probability = 14/20
= 7/10.

Answer:
r = -9/10
Step-by-step explanation:
Given
7/10 = r - (-8/5)
Required
Solve for x
7/10 = r - (-8/5)
We start by opening the bracket
7/10 = r + (- -8/5)
7/10 = r + (8/5)
7/10 = r + 8/5
Subtract 8/5 from both sides
7/10 - 8/5 = r + 8/5 - 8/5
7/10 - 8/5 = r
Solve the fraction by taking their LCM
(7 - 16)/10 = r
-9/10 = r
Reorder the above
r = -9/10
Hence, the value of r is -9/10
