Answer:

Rational

Step-by-step explanation:

We first have to define what these numbers mean:

Real numbers are all the numbers on the number line, they are not imaginary numbers that cannot be quantified on the number line.

Rational numbers are numbers that have either terminating decimals or recurring decimal, for example 5.3 (terminating decimal) or 1.333...(recurring decimal). I did not use the traditional definition of "a/b where a and b are integers and b ≠ 0" because it poses some problems. For instance 22/7 fulfills this condition but it is not a rational number! So it is best defined the way I just defined it.

An irrational number is a number that does not have terminating and recurring decimal, like 3.565215805.....

Integers are real numbers that are whole numbers.

Looking at the situation, which is the money in a bank account. The value will be a number that is rational because it is always an exact amount and this implies that it will always be a terminating decimal. Note that 45.00 is also a terminating decimal.

The product of a constant factor 15 and a 2-term factor x+4
dezoksy [38]
The product of 15 and x+4 is 15(x+4) = 15x+60. This is a linear binomial.

4x^3-2x-9-(2x^3) is a cubic trinomial. In your original question, I'm not sure what the 5x+3 means.

06.07 Equivalent Expressions

by Dominique

The ending of Sarah 's story

By the end of the day Sarah had found 4 shark teeth . John had found 2 shark teeth , together they had 6 shark teeth. When Sarah and John showed her neighbor the teeth he or she paid Sarah $30 dollars. Sarah and John had split the money so John would have $15 dollars and Sarah would have $15 dollars.

i already did this exact answer with someone else so i just copied my answer from that and placed it on this on

Step-by-step explanation:

Substitution: Two

Use substitution to prove that your two expressions are equivalent.

7(9j+ 6j + 2)

63j + 14 + 42j

63 x 1 + 42 x 1 + 14

63 x 1= 63

42 x 1=42

42 + 63 + 14

42 + 63 = 105

105 + 14 = 119

Part 2: Writing Expressions

Substitution : One

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

The product of seven and the sum of the product of nine and some number, two, and the product of six and some number.

Use substitution to prove that your two expressions are equivalent.

7(9j+ 6j + 2)

7( 9 x 1 + 6 x 1+ 2 )

9 x 1= 9

6 x 1= 6

7 ( 9 + 6 + 2 )

9 + 6 = 15

15 + 2 += 17

7 x 17 = 119

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.

My expression is 7(9j+ 2 + 6j) .

Writing Equivalent Expressions

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 she can earn.

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.

7(9j+ 2 + 6j) = 7(9j+ 6j + 2) = The Commutative Property of Addition.

7(9j+ 2 + 6j) = 63j + 14 + 42j = The Distributive Property
