Answer:
52 32- cent stamps and 26 13-cent stamps
Step-by-step explanation:
Let x be the 32-cent stamps and y be the 13-cent stamps then...
x=2y
32x+13y=2002 (note that $20.02 is 2002 cents)
We can solve using substitution (substitute 2y for x)
32(2y)+13y=2002
64y+13y=2002
77y=2002
y=26
x=2(26)
x=52

Step-by-step explanation:
Answer:
The inequalities are used as:
a > b (a is greater than b)
a < b (a is smaller than b)
a ≤ b (a is smaller than or equal to b)
a ≥ b (a is greater than or equal to b)
a ≠ b (a is different than b)
Now, let's apply these for our two numbers.
-8 and -13
We know that for negative numbers, the larger absolute value means that the number is smaller, then we relate these numbers in the next 3 ways.
-8 > -13 (-8 is greater than -13)
-13 < 8 (-13 is smaller than -8)
-13 ≠ -8 (-13 is different than -8)
