Help please :
Hiro evaluated a list of algebraic expressions. The expressions all contained one or two variables, and some contained constants and/or coefficients. He substituted only integers for the variables.



Read Hiro’s notes, then create expressions that match his results. Think of more than one expression for each note if possible.

A)I always end up with 2 more then a multiple of 3.

Answer:

Step-by-step explanation:

Possible Expressions:

1) 2 + 3x

2) x + 5

3) 3x + 2

4) 2x + 8

Examples:

1) 2x + 5 = 3n + 2

2) 4y + 1 = 3n + 2

3) 3x + 7 = 3n + 2

4) 6y - 2 = 3n + 2

Please help this is worth 15 points!

how many solutions does 4x - 2 = 3x - 2 have
1) no solution
2) one solution
3) infinitely many solutions

Module 06: Project Option 1
Instructions
Sarah’s neighbor offers to pay her $5 for every shark tooth she finds on the beach. After collecting only three shark’s teeth, Sarah decides to share the opportunity with her friend John. Sarah can find shark teeth twice as fast as John, but she can earn even more money with his help.


Sarah can use the expression 5(2j + 3 + j) to represent the amount of money they can earn.

Part 1: Writing Expressions
1. Write an expression that looks like Sarah’s expression: 5(2j + 3 + j). Replace the coefficients so that your expression is not equivalent. You may use any number that you choose to replace the coefficients. Be sure to leave the variables the same. For example, 8(3j + 7 + 3j) looks like Sarah’s expression but is not equivalent.


2. Translate the new algebraic expression you created in Question 1 to a verbal expression.


Part 2: Writing Equivalent Expressions
3. You will now use mathematical properties to create two expressions that are equivalent to the expression you created in Question 1. Make sure you show all steps in your work.
a. Use either the commutative property or combine like terms to create an equivalent expression.


b. Use the distributive property to create an equivalent expression.


4. Pick a number from 1 to 10. Use that number to verify your three expressions (the original, the one from 3a, and the one from 3b) are equivalent by substituting it into each expression. Show all your work for complete credit.

Part 3: Finish the Story
5. Write a few sentences to end Sarah’s story. How many shark teeth did she find? How many shark teeth did John find? How much money did they earn?

6. Choose a method to present your assignment. You may submit your work in a Word Document or you may choose to develop a PowerPoint presentation or video recording of yourself. Use your creativity! Make sure to include the information from all three parts in your Word Document or presentation.

James determined that these two expressions were equivalent expressions using the values of x = 4 and x = 6. Which statements are true? Check all that apply.

7 x + 4 and 3 x + 5 + 4 x minus 1
When x = 2, both expressions have a value of 18.
The expressions are only equivalent for x = 4 and x = 6.
The expressions are only equivalent when evaluated with even values.
The expressions have equivalent values for any value of x.
The expressions should have been evaluated with one odd value and one even value.
When x = 0, the first expression has a value of 4 and the second expression has a value of 5.
The expressions have equivalent values if x = 8.
