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: 25(10j + 18 + 5j)
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.
Twenty five times the sum of ten j plus 3 plus j
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.
Using commutative property of addition, the expression in question 1 can be rewritten as follows:
25(10j + 18 + 5j) = 25(10j + 5j + 18)
Using distributive property of multiplication over addition, the expression in question 1 can also be rewritten as follows:
25(10j + 18 + 5j) = 250j + 450 + 125j
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.
Answer:
the answer is in PREZI, just search up this question and u will find it : )
by the end of the day Sarah had found 4 shark’s teeth. John found 2 shark teeth .total they found 6 shark teeth .when Sarah and John showed it to their neighbours they paid her 30 dollars the splited the money by 15 dollars for each
the photos is given in order. so write accordingly .
The diagonals of rectangle. QRST intersect at P. Given that m<PTS = 34° and QS=10 , find QP.
Answer:
QP = 5
Step-by-step explanation:
since QRST is a rectangle, and QRST intersect at P, then QTS and QRS are right triangles.
because <T is a right angle, line TR passes through the midpoint of line QS, therefore 2(QP) = QS
10/2 = 5
By the property of diagonal in a rectangle are equal and bisect each other measure of QP is 5 units.
What are the area and perimeter of a rectangle?We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.
Given, QRST is a rectangle, QS and RT are the diagonals of the rectangle
QRST.
By properties of rectangles, we know a rectangle is a parallelogram in which opposite sides are equal and diagonals bisect each other.
Given, QS is 10 units and QS = 2QP.
10 = 2QP.
QP = 10/2.
QP = 5.

ACME Company's expected sales can be modeled by g(t) = 13 – 21? + 4t - 7, where g(t) is measured in thousands
of dollars and t is the number of years after 2008. Find the average rate of change in expected sales from 2009 to
2015.
Select one:
O a. -$45,000
O b. $45,000
O c. $36,000
O d. $270,000
You can use the given function to evaluate the expected sales at year 2009 and 2015 and use the net difference divided by time as the average rate of change.
The average rate of change in expected sales from 2009 to 2015 is given by $12,059,941
How to find the average rate of change of something?Let the thing that is changing be y and the thing with which the rate is being compared is x, then we have the average rate of change of y as x changes as:
[tex]\text{Average rate} = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]
where when
[tex]x = x_1, y = y_1\\and \\x = x_2, y = y_2[/tex]
Using the above method to calculate the needed average rateSince the sales is given by the function [tex]g(t) = t^3 - 2t^2 + 4t - 7[/tex], and the inputs are 2009 and 2015, thus, evaluating g(t) (sales) at those values of t, we get:
[tex]g(2009) = 8023737057[/tex] (replaced 2009 with t and calculated)
[tex]g(2015) = 8096096703[/tex] (replaced 2015 with t and calculated)
Using these values to calculate the average rate
[tex]\text{average rate} = \dfrac{g(2015) - g(2009)}{2015 - 2009} = \dfrac{72359646}{6} = 12059941\\[/tex]

What is the distance of
CD
given that
C (5,-2) and D (-3,8)
Leave your answer as a square root.
Answer:
CD = [tex]\sqrt{164}[/tex]
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = C(5, - 2) and (x₂, y₂ ) = (D(- 3, 8)
d = [tex]\sqrt{(-3-5)^2+(8+2)^2}[/tex]
= [tex]\sqrt{(-8)^2+10^2}[/tex]
= [tex]\sqrt{64+100}[/tex]
= [tex]\sqrt{164}[/tex]
= 2[tex]\sqrt{41}[/tex] ← in simplest form
As, we have C (5, - 2) and D (- 3, 8), to find CD let's use distance formula :
[tex] \underline{\boxed{\tt{Distance \: between \: two \: points = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2}}}}}[/tex]
Here,
x₁ = 5x₂ = - 3y₁ = - 2y₂ = 8So, by filling values :
[tex] \sf : \implies CD = \sqrt{(-3 - 5)^{2} + (8 - (-2))^{2}}[/tex]
[tex] \sf : \implies CD = \sqrt{(-8)^{2} + (8 +2))^{2}}[/tex]
[tex] \sf : \implies CD = \sqrt{64 + (10)^{2}}[/tex]
[tex] \sf : \implies CD = \sqrt{64 + 100}[/tex]
[tex] \sf : \implies CD = \sqrt{164}[/tex]
Hence, distance of CD is [tex] \bold{\sf \sqrt{164}.}[/tex]

PLEASE HELP ME
Answer:
20
Step-by-step explanation:
115+x = 135 (remote interior angles)
x = 135-115
x = 20
Please Make Me Brainlist
Answer:
20
Step-by-step explanation:
first look at the line which says a and 135, they add up to 180 so
a + 135 =180
a= 180-135
a= 45
Then to find the x we will have to add all the angles inside the triangle which would add up to 180
So,
x+115+45=180
x+160=180
x=180-160
x=20
THEREFORE X = 20⁰
write the equation of this line in y= mx + b form:
Answer:
y = 2.5x + 3
Step-by-step explanation:
y = mx + b
y = 2.5x + 3
As you can see, each unit is not 1, its 0.5. We need to go up 5 times, and so 0.5 times 5 gives us 2.5, and thats how i got my slope.
I got 3 as my y-intercept because it's were the line intersects the y axis.
Hope this helped!
Have a supercalifragilisticexpialidocious day!
Answer:
y=5x+3
Step-by-step explanation:
Slope: y2-y1 over x2-x1 so it will be 3-(-2) over 0-(-1) and the answer will be 5.
Y intercept: In order to find the y intercept it is necessary to replace the y an x coordinate in the equation: y= mx+b and replace 3=5(0)+b... simplifying would be 3=b
so the final answer would be y=5x+3

The ratio is 24:1000 or 0.024.
What is Ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
72 millimeters to 3 meters
Now, Convert 3 meter to millimeter
3 meter= 3 x 1000
= 3000 mm

Find the area of a circle whose area equals the half of the sum of the areas of two circles with radil 2 and 3.
13 (pi)
5 (pi)
6.5 (pi)
Step-by-step explanation:
step 1. if r = 2, then its area = (pi)r^2 = (pi)(4) = 4pi
step 2. if r = 3 then its area = (pi)r^2 = (pi)(9) = 9pi
step 3. so A is the area of a circle half the sum of our circles with r = 2 and r = 3.
step 4. A = (4pi + 9pi)/2 = 13pi/2 =6.5(pi).
