Answer:
1. =
2. <
3. <
Step-by-step explanation:
Note: When comparing decimals you always place both decimals right above each other.
1 is equal to because once you put a 0 behind the 2.1 they are both the same.
2.10
2.1 <add 0 as space holder
2 is less than because they are both negative you are looking for which one is closest to zero.
-4.5 <add 0 as place holder
-4.25 <closest to zero
3 is less than because 
(pie) equals 3.141592654 which is less than 3.2.
3.141 <do not need to add whole decimal
3.2 <add two 0's as a placeholder
Answer:
a = -5
Step-by-step explanation:
15 - a = 20
Move the constant of 15 to the other side by subtracting it.
-a = 5
Divide by -1 to make a positive.
a = -5
Check.
15 - (-5) = 20
15 + 5 = 20
20 = 20
What type of graphs
if it is a bar graph look at the hights or the ranges
if it is a line graph look at how much it drops or how much it raises by
if it is just any kind of graph look at y and x axis how much does it skip
