Answer: 15.7 minutes
Step-by-step explanation:
Let x be the time in the beginning (in minutes).
Given: The track team is trying to reduce their time for a relay race.
First they reduce their time by 2.1 minutes.
Then they are able to reduce that time by 10
If their final time is 3.96 minutes, then
x-t1-t2= 3.6
x= 3.6+ t1+ t2
x= 3.6+ 2.1+ 10
x= 15.7
Hence, their beginning time was 15.7 minutes.

Step-by-step explanation:
Answer:
a. 0.169x+69.11 > 0.126x+76.74
Step-by-step explanation:
So, there's a lot of talk in the question statement. Of course, it presents some important data... but it's also meant to confuse you.
We can boil it down to the following life expectancies :
Men = 0.169x+69.11
Women = 0.126x+76.74
Then they ask you to write with that men have a greater life expectancy than woman using the models above.
Start by writing the goal:
men > women
Then replace "men" by the model and "women" by the model:
0.169x+69.11 > 0.126x+76.74
And you have your answer.
