3. 5x-2
4. -3x+15
5. -4x-28
6. -4x+ 12
7. 8x+ 40
To find the answer you need to multiply the number outside of the parentheses by each number/variable in the parentheses.
For example, number 9 says 8(-x-6) you would have to "distribute" the 8 out the both the variable and the number.
8 multiplied by -x is -8x because a negative times a positive is a negative and 8 multiplied by -6 is -48. So there for your answer would be -8x-48

You have to make sure to also remember the multiplying rules:
positive times a positive= positive
positive times a negative= negative
negative times a negative= positive

Answer:

the handle will end up on the left side

Step-by-step explanation:

The cup is rotated 180 degrees clockwise. Therefore, I assume the rotation is about the center of the bottom of the cup. Also, only the cup is rotated, not the saucer (although this makes no difference in this problem).

The result is that the handle will end up on the left side. The cup will still be right side up.

The left side is the answer

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.

06.07 Equivalent Expressions

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

What is an expression?

An expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them. In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

here, we have,

Given the expression  5 p + 6 = 7,

to know the value of variable p. we need to make p the subject of the formula as shown;

Given  5 p + 6 = 7

Step 1:

Subtract 6 from both sides

5p+6-6 = 7-6

5p = 7-6

Step 2:

We will then divide both sides by the coefficient of p i.e 5 to have;

5p/5 = (7 - 6)/5

p =  (7 - 6)/5

Hence, the correct expression of variable p is p = (7 - 6)/5.

The amount in the account after compound interest of 1 year is $ 6890 and after 2 years is $ 7303.4.

The principal amount is given as $ 6500.

Rate of compound interest = 6%

The compound interest formula is given as [tex]A = P (1 + \frac{r}{n})^{nt}[/tex]

where, P = Principal amount

r = rate of interest divided by a hundred

n = number of times compounded

t = time in years

a) Amount in the account after 1 year is

[tex]A = 6500(1 + \frac{0.06}{1})^{1}[/tex]

A = 6890

The amount in the account after 1 year is $ 6890.

b) Amount in the account after 2 years is

[tex]A = 6500(1 + \frac{0.06}{1})^{2}[/tex]

A = 7303.4

The amount in the account after 2 years is $ 7303.4.

A doctor replaces the fish tank in her office. Do the fish have more room to swim in the new tank? Find the volume of each tank to find out.

The volume of the old fish tank, in cubic feet:

Answers

Answer: The volume of the old fish tank is 10 ft. The volume of the new fish tank is 8 ft.

Step-by-step explanation: The formula for a rectangle is A=l*w. Multiply the length and the width of the tank. 4*2 1/2 = 10. And 4*2 = 8. So the old fish tank is bigger than the new one.

At a local park, Jared can choose between two circular paths to ride his bicycle. One path has a diameter of 240 yards, and the other has a radius of 380 yards. Jared is curious about two things. He wants to know how much farther he can ride his bike on the longer path than the shorter path if he rides his bike around the path once? Jared also wants to know how big of an area each circle covers. Use 3.14 for π.

Part A: Using the formula for circumference, find the circumference of both paths. (4 points)
Part B: Use the formula for area and solve for the area of each circle. (4 points)
Part C: How much farther can he ride his bike on the longer path if he goes around one time? (2 points)
