Answer:
1. She orders them from least to greatest.
2. She orders them from least to greatest using their absolute values. (absolute value means to just ignore the negative signs)
3. She orders the from greatest to least.
Answer:
A is b/c the 2 minutes and 54 seconds are 174 seconds and the .29 also gets carried over, so it is 174.29. (You are converting minutes to seconds [60 seconds=1 minute])
B the average time of the four runners would be 43.5725 seconds, b/c 174.29/4=43.5725
U need to use the distributive property ok? The u have to add or subtract the number on both sides bring it down and the you have to divide
The answers are in slope-intercept form, so you can see that the slope (coefficient of x) is only correct for choices b and c.
When you substitute x=3/2 into those equations, you find that b gives y=6 (correct) and c gives y=0 (incorrect).
The appropriate choice is ...
... b.) y = 2x+3
