Answer:
The values of k are all real numbers greater than 3
Step-by-step explanation:
we have
![(\frac{k}{3})12 > 12](https://tex.z-dn.net/?f=%28%5Cfrac%7Bk%7D%7B3%7D%2912%20%3E%2012)
Solve for k
Divide 12 by 3
![4k > 12](https://tex.z-dn.net/?f=4k%20%3E%2012)
Divide by 4 both sides
![4k/4 > 12/4](https://tex.z-dn.net/?f=4k%2F4%20%3E%2012%2F4)
![k > 3](https://tex.z-dn.net/?f=k%20%3E%203)
The solution is the interval ------> (3,∞)
All real numbers greater than 3
Answer:
Talking 65 minutes, $ 6.50 must be paid.
Step-by-step explanation:
Since your cell phone plan is by the minute, and each minute of use cost $ 0.10, to create a relation that represents the amount spent, A, per minute, m, of call time, and then use the relation to find the amount spent if you talk 65 minutes, the following calculations must be performed:
0.10 x M = A
0.10 x 65 = A
6.50 = A
First, put 30 over 1. then line it up. finally, you multiply.
my math teacher tought me this: multiplying fractions is no problem, top times top and bottom times bottom.
