Answer:
x = -3
Step-by-step explanation:
6x +7 -2x +4 = 4(-3x-5) - 17
6x + 7 -2x +4 = -12x -20 -17
6x -2x +12x = -20 -17 -7 -4
16x = -48
x = 3
I'm going to just guess on this one. I really think that the second one is the best answer for me. If I'm wrong, I'm really sorry for taking up this space!!!
You can use the formula
speed=distance/time
20.88=145/x
x=145/20.88
x=6.9 hours -it will take 9 hours
Answer:
Step-by-step explanation:
Let us assume that she makes 10 minutes of call.
Telecorp has a flat rate of 7 cents per minute. If she uses this cell phone service, the amount that she would pay for 10 minutes of call is
0.07 × 10 = $0.7
America's charges 25cents per call. If she uses this cell phone service, the amount that she would pay for 10 minutes of call is $0.25
Phone busters charges 35 cents per call and 2 cents per min. If she uses this cell phone service, the amount that she would pay for 10 minutes of call is
0.35 + 10 × 0.02
= 0.35 + 0.2
= $0.55
The cheapest service is that of America's. Therefore, she should choose it.
