(1) let "r" denote number of rabbits, "c"  number of chickens

Set up the equations:

r + c = 1000\\4r + 2c = 3150\\\\-2r -2c = -2000\\4r + 2c = 3150\\\\2r = 1150\implies r = 575\implies c = 425

Answer: There are 575 rabbits and 425 chickens

(2) m - number of Mike's stamps, a - number of Andrew's stamps.

Set up equations:

m = 4a\\m-8 = 2(a+8)\\\\4a-8=2a + 16\\2a = 24\implies a = 12\implies m = 48\\

Answer:  Mike has 48 stamps. Andrew has 12 stamps.

Travka [436]

Answer:

<h2>On the 15th day his best time for the day is 3 minutes.</h2>

Step-by-step explanation:

The line that best fits is

y=-0.03x+3.45

Where x is days and y is time in minutes. So, we have x=15, replacing this in the equation and solving for y, we have

y=-0.03(15)+3.45=-0.45+3.45=3

Therefore, on the 15th day his best time for the day is 3 minutes.
