400 - 2 x Age = 244
-2*Age = -156
Age = 78 years
Answer:
357 minutes
Step-by-step explanation:
I subtracted 9 cents/minute from the 23 cents/minute to get 14 cents to get the difference between the two per minute charges. I then divided the monthly cost of $49.95 by .14 to get 356.79... So if you used 357 minutes in a month, the second plan would be 3 cents cheaper at $82.08 (.09 x 357= 32.13 + 49.95), vs. the first plan costing $82.11 (.23 x 357). At 356 minutes the first plan would still be cheaper.

Answer:
![\[\frac{3}{4}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7B3%7D%7B4%7D%5C%5D)
miles
Step-by-step explanation:
The relay team consists of 4 people.
Total distance covered by 4 people = 3 miles
Each person runs the same distance.
This means that each person will run a distance equal to:
![\[\frac{distance}{persons}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7Bdistance%7D%7Bpersons%7D%5C%5D)
![\[=\frac{3}{4}\]](https://tex.z-dn.net/?f=%5C%5B%3D%5Cfrac%7B3%7D%7B4%7D%5C%5D)
So each person in the relay team of 4 will run a distance of miles to cover the entire length of 3 miles.
