Question

Hello,
I am hoping you would be able to help me with a few problems I am having. Can you tell me if I am doing these problems correct and/or let me know where I am performing the missed calculations? Also, can you help explain, define, and give examples of some of the key concepts?

1.) Guidance Original Problem: Mr. Smith is thinking of a number. Three times the number minus 12 equals 36. What is the number Mr. Smith is thinking of?

Identify /Explain the Guess, Check, and Revise Problem Solving Strategy. Also, list the seven steps you take while using this strategy.

Answer 1

Give Extra Help  Create two other word problems, like the one of above, to give the student/reader extra practice. Also, give the answer at the end of the problem.


2.) Guidance When graphing inequalities, like -4 > t, how do I know whether the circle is open or closed? Also, how do I know which way to shade down the number line? What does the shading represent?


3.) Guidance  Please graph, solve, and explain all steps taken for the following inequalities:

a. 9 – x > 4
b. – 6 t < 12

Answer 2

Qn1. let the number be x.
3x -12 = 36
3x = 48
x= 16

Answer 3

2. if it is -4>t the circle is open. for
\[-4\le t\] the circle is close. The difference being whether the number itself is included or not.
