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 she can earn.

Part 1: Writing Expressions
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.


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


Part 2: Writing Equivalent Expressions
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.



Use either the commutative property or combine like terms to create an equivalent expression.



Use the distributive property to create an equivalent expression.


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
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 Sarah earn?
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

1) 2x + 5 = 3n + 2

Due to the demand of their chicken sandwiches, Popeyes decided to change the price from $2.29 to $2.59. Express this change as a percentage.

A-12% increase
B-12% decrease
C-13% increase
D-88% increase

Answers

Answer: C

Step-by-step explanation: You can use the percent error formula if you know it or just do:

value 2 - value 1

                                            x 100 = percent

absolute value of value 1    

The correct option C-13% increase. The price of the chicken sandwiches percentage increased by 13%.

Explain the term percentage change?Finding the differences between the two values in such a time series, dividing the difference by the initial value, then multiplying by 100 are used to determine the percentage change here between two values. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

For the stated question;

Original price of the chicken = $2.29

Increased price of the chicken = $2.59.

Let x be the percentage increase:

Thus,

2.29 + x% of 2.29 = 2.59

2.29 + 2.29x / 100 = 2.59

229 + 2.29x = 259

2.29x = 259 - 229 = 30

x = 30 / 2.29 = 13.1

x = 13 % (approx)

Thus, the price of the chicken sandwiches increased by 13%.

Answers

Answer:

Step-by-step explanation:

Simplifying

14 + -3z = 0

Solving

14 + -3z = 0

Solving for variable 'z'.

Move all terms containing z to the left, and all other terms to the right.

Add '-14' to each side of the equation.

14 + -14 + -3z = 0 + -14

Combine like terms: 14 + -14 = 0

0 + -3z = 0 + -14

-3z = 0 + -14

Combine like terms: 0 + -14 = -14

-3z = -14

Divide each side by '-3'.

z = 4.666666667

Simplifying

z = 4.666666667

Answer: D

Step-by-step explanation:

You can either calculate what the rates will give, or try to compare them :

We have 5, 1 (hidden), and 3 as denominators, so 8*3*1 = 24

We'll take that as denominator.

Bank A : [tex]2.35 = \frac{2.35*24}{24}=\frac{56.4}{24}[/tex]

Bank B : [tex]2\frac{1}{3}=\frac{1*2*8}{3*8}=\frac{16}{24}[/tex]

Bank C : [tex]2\frac{5}{8} = \frac{5*2*3}{8*3} =\frac{30}{24}[/tex]

Bank D : [tex]2.61=\frac{2.61*24}{24} = \frac{62.64}{24\\}[/tex]

And now, let's compare the numerators !

[tex]\frac{16}{24} < \frac{30}{24} < \frac{56.4}{24} < \frac{62.64}{24} \\Bank B < Bank C < Bank A < Bank D[/tex]

A. The statement is true, but the inverse is false.

B. The statement is false, but the inverse is true.

C. Both the statement and its inverse are false.

D. Both the statement and its inverse are true.

Answers

A. The statement is true, but the inverse is false. (explanation): An inverse statement is to take the negation of both the hypothesis and the conclusion (basically the opposite). the opposite of “If an angle measures 43°, then the angle is acute.” would be “If an angle does not measure 43°, then the angle is not acute” which isn’t true because an angle any less than 90° is acute and isn’t only measured 43°.

Calculate the area of the regular pentagon below:

Answers

Answer: 858.55 in

Step-by-step explanation: You calculate the area of the triangle ( 22.3 x 15.4/2), then you multiply the result by 5.

Answer:

858.55

Step-by-step explanation:

Area of triangle = 1/2BH

1/2(22.3*15.4) = 171.71

Because there is five sides on the pentagon we have to multiply the 172.71 by 5 to get the final answer.

171.1(5) = 858.55

Answer:

845 miles

Step-by-step explanation:
