Answer to Problem 36PPS
The Ms. Cooper’s daily salary is
Explanation of Solution
Substitute 20 for
Therefore, the distance in kilometers corresponds to 20 miles is
(c)
To find: The number that is same in kilometers and miles.
(c)
Answer to Problem 36PPS
The number is 0.
Explanation of Solution
As shown in the graph 0 is the only number because this is the point on the graph where x value and y values are same.
Therefore, the number is 0.
