(a)
To write: the statement “ x is positive” in terms of inequality.
(a)

Answer to Problem 37E
x>0
Explanation of Solution
Given information:
x is positive
Calculation:
Consider the given statement.
x is positive
Now, positive number is always greater than 0.
So, x>0 .
(b)
To write: the statement “ t is less than 4” in terms of inequality.
(b)

Answer to Problem 37E
t<4
Explanation of Solution
Given information:
t is less than 4
Calculation:
Consider the given statement.
t is less than 4
Now, less than sign is '<' .
So, t is less than 4, in terms of an inequality can be written as
t<4 .
(c)
To write: the statement “ a is greater than or equal to π ” in terms of inequality.
(c)

Answer to Problem 37E
a≥π
Explanation of Solution
Given information:
a is greater than or equal to π .
Calculation:
Consider the given statement.
a is greater than or equal to π
Now, greater than equal sign is '≥' .
So, a is greater than or equal to π , in terms of an inequality can be written as
a≥π .
(d)
To write: the statement “ x is greater than −5 and less than 13 ” in terms of inequality.
(d)

Answer to Problem 37E
−5<x<13
Explanation of Solution
Given information:
x is greater than −5 and less than 13 .
Calculation:
Consider the given statement.
x is greater than −5 and less than 13
Now, greater than sign is '>' and less than symbol is '<' .
So, x is greater than −5 and less than 13 , in terms of an inequality can be written as
−5<x<13 .
(e)
To write: the statement “the distance between p and 3 is at most 5 ” in terms of inequality.
(e)

Answer to Problem 37E
|p−3|≤5
Explanation of Solution
Given information:
The distance between p and 3 is at most 5 .
Calculation:
Consider the given statement.
The distance between p and 3 is at most 5 .
Distance between two points a and b can be written as
d(a,b)=|a−b|
Now, for the word “at most” the required symbol is '≤' .
So, the distance between p and 3 is at most 5 , in terms of an inequality can be written as
d(p,3)≤5|p−3|≤5 .
