Reasoning a. Solve
b. Solve
c. Compare the results of parts (a) and (b).
d. Which method do you prefer? Explain.
a.
To calculate: Gather variable terms on left side and constant terms on the right side of the inequality.
Answer to Problem 25P
Explanation of Solution
Given information: The inequality
Calculation:
Let’s gather variable terms on the left side by subtracting both sides 2v.
It gives
Add both sides 5
b.
To calculate: Bring all variable terms to the right side of the inequality and constants to the left side of the equation.
Answer to Problem 25P
Explanation of Solution
Given information: The inequality
Calculation:
Subtract both sides 3v
Subtract both sides 10.
Divide both sides by -1.
It can be rewritten as
c.
To find: The method do you prefer part A or partB?
Answer to Problem 25P
I would prefer the method the part A is used because we could solve the inequality within few steps.
Explanation of Solution
Both give the same answer in part A and part B.
d.
To find: The method do you prefer?
Answer to Problem 25P
I would prefer the method the part A is used because we could solve the inequality within few steps.
Explanation of Solution
Even though both methods gives us same answer first way is simple, easy and less steps are needed.
