Guided Practice

Do you know HOW?
Use the input/output table for 1 and 2.
Envision Math 6th Grade Answer Key Topic 2.7 Using Expressions to Describe Patterns 2

Question 1.
If the input number is 8, what is the output number?
Answer:
11
Explanation:

Question 2.
Write an algebraic expression that describes the output pattern.
Answer:
x + 3
Explanation:

Do you UNDERSTAND?
Question 3.
Suppose that Delvin earned $36 mowing lawns. What input and output entries would you add to his table?
Answer:
IN: $36; OUT: $18
Explanation:

Question 4.

Answer:
See margin.
Explanation:

Question 5.
What is the algebraic expression that describes the output pattern for the table above if the input is x?
Answer:

Answer:

Question 7.
Write an algebraic expression that describes the output pattern if the input is a variable a.
Answer:
2a
Explanation:

Use this table for 8 and 9.
Envision Math 6th Grade Answer Key Topic 2.7 Using Expressions to Describe Patterns 4

Question 8.
Copy and complete the table.
Answer:

Question 9.
Write an algebraic expression that describes the relationship between the input and output values.
Answer:
x ÷ 3
Explanation:

An input/output table is a table of related values. Identify the pattern.
What is the relationship between the values?
\(\frac{1}{2}\) (84) = 42 → 42 is half of 84
\(\frac{1}{2}\) (66) = 33 → 33 is half of 66
\(\frac{1}{2}\) (50) = 25 → 25 is half of 50.

The pattern is: \(\frac{1}{2}\) (INPUT) = OUTPUT
Let x= INPUT.
So, the pattern is \(\frac{1}{2}\) x.
Use the pattern to find the missing values.
Envision Math 6th Grade Answer Key Topic 2.7 Using Expressions to Describe Patterns 5
\(\frac{1}{2}\) (22) = 11
\(\frac{1}{2}\) (30) = 15

Problem Solving

Use the input/output table at right for 10 and 11.

Question 10.
Hazem keeps \(\frac{1}{3}\) of the tips he earns. Also, he gets $1 each night to reimburse his parking fee. This information is shown in the input/output table. Write an algebraic expression that describes the output pattern if the input is the variable k.
Answer:
(k ÷ 3) + 1 or \(\frac{1}{3}\) k + 1
Explanation:

Question 11.
How much money would Hazem keep in a night if he takes in $36 in tips?
Answer:
$13
Explanation:

Use the input/output table at right for 12 and 13.
