Answer:
4.75 hours.
Step-by-step explanation:
We have been given that Kathleen worked for 4 hours and 45 minutes.
We will convert 45 minutes to hours by dividing 45 by 60 as one hour has 60 minutes.
Therefore, she should write 4.75 hours on her time card.

Step-by-step explanation:
w(n) = 2n + 1;
Let n = 6
w(6)= 2*6 +1

= 13
Answer:
12.50 + (7.5)(h-1) ≤ 50
6 hours or less
Step-by-step explanation:
The first hour is 12.50. Each additional hour is 7.50
Let h be the number of hours
12.50 + (7.5)(h-1)
We use h-1 since the first hour is 12.50
This must be less than or equal to 50
12.50 + (7.5)(h-1) ≤ 50
Now we solve the inequality
Subtract 12.50 from each side
12.50-12.50 + (7.5)(h-1) ≤ 50-12.50
(7.5)(h-1) ≤ 37.50
Divide by 7.5 on each side
(7.5)/7.5(h-1) ≤ 37.50/7.5
h-1 ≤ 5
Add 1 to each side
h-1+1 ≤ 5+1
h ≤ 6
We can only rent for 6 hours or less
Answer: x is less than or equal to 50/7
Step-by-step explanation:
7x-18<=32 is solve just like a normal equation. Add 18 on either side so that
7x<=32+18
7x<=50
x<=50/7.
