2(2y-x=8)
4y-2x=16
-(y-2x= -5)
3y +0x= 21
3y=21
y=7
2(7)-x=8
14-x=8
9=x
Dan is getting balloons for his grandfather's birthday party. He wants each balloon string to be 9 feet long. At the party store, string is sold by the yard. If Dan wants to get 83 balloons, how many yards of string will he need?
Answer:
I would think its 249 because 9 divided 3= 3 because 3 feet is 1 yard and then you do 83x3 and then you get 249.

So one day, this young girl, who was only eleven years old at the
time, started to make speeches and write blogs saying that girls should be
allowed to go to school as well.
Question: How do you think the people with political power, who were
against girls in school, might have reacted when she started doing this?
They would be outraged and make a mockery of the idea, since they belived that girls should remain at home doing chores and learn to cook instead of getting a education.

Answer:
B. 3b -0.51b
Step-by-step explanation:
The factor outside parentheses multiplies each term inside parentheses.
3(b -0.17b) = 3(b) +3(-0.17b) = 3b -0.51b . . . . note the minus sign
The term 3b represents the original price of 3 loaves of bread.
The term -0.51b represents the total discount on the price of 3 loaves of bread.
Which function is graphed? ! Please answer quickly
Answer:
f(x) = - 1 should be the answer because the function is horizontal.
Step-by-step explanation:
Select the statements that are true about the graph.
The y-intercept of the graph is (0, -8).
The vertex is located at (-1,-9)
The graph has y-intercepts at (-4.0) and (2.0).
The graph has a minimum.
The graph has zeros of -4 and 2.
The solution of the quadratic function represented by the graph is (-1,-9).
The graph has a maximum.
Answer:It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.
Step-by-step explanation:
The Y intercept of a straight line is simply where the line crosses the Y axis.
Example
Y intercept
In the above diagram the line crosses the Y axis at 1.
The Y intercept is equal to 1 and the point is written as (0,1). Notice that for the y-intercept the x-coordinate of the point is always zero..
A large tank is partially filled with 100 gallons of fluid in which 40 pounds of salt is dissolved. Brine containing 1 2 pound of salt per gallon is pumped into the tank at a rate of 6 gal/min. The well-mixed solution is then pumped out at a slower rate of 4 gal/min. Find the number of pounds of salt in the tank after 30 minutes. (Round your answer to two decimal places.
Answer:
76.09 pounds
Step-by-step explanation:
From the information given:
[tex]R_{in} = (\dfrac{1}{2} \ lb/gal ) *(6 \ gal/min)[/tex]
[tex]R_{in} =3 \ lb/min[/tex]
At a slower of 4 gal/min, the solution gets pumped out;
So,
[tex]R_{out} = \dfrac{4A}{100+(6-4)t }[/tex]
[tex]R_{out} = \dfrac{2A}{50+t }[/tex]
The differential of the equation is:
[tex]\dfrac{dA}{dt}+ \dfrac{2}{50+t}A=3 ---(1)[/tex]
For the linear differential equation, the integrating factor is determined as:
[tex]\int_e \dfrac{2}{50 +t}dt = e^{2 In|50+t|[/tex]
[tex]= (50+t)^2[/tex]
Multiplying [tex](50+t)^2[/tex] with the above integration factor;
[tex](50+t)^2 \dfrac{dA}{dt} + 2 (50+t) A = 3(50 +t)^2[/tex]
[tex]\dfrac{d}{dt}[ (50 +t)^2 A] = 3(50+t)^2[/tex]
[tex](50+t)^2 A = (50 +t)^3 + c[/tex]
[tex]A = (50 +t) + c (50 +t )^{-2}[/tex]
By using the given condition:
A(0) = 40
40 = 50 + c (50)⁻²
10 = c(50)⁻²
OR
c = -10 × 2500
c = -25000
A = (50 + t) - 25000(50 + t)⁻²
The number of pounds of salt in the tank after 30 min is:
A(30) = (50+30) - 25000(50 + 30)⁻²
[tex]A(30) = 80 - \dfrac{25000}{6400}[/tex]
[tex]A(30) = 76.09 \ pounds[/tex]
Thus, the number of pounds of salt in the tank after 30 min is 76.09 pounds.

jester has a piece of wood measuring 1 and 2/3 m.he needs to cut in pieces measuring 3/4 m long.how many pieces of wood did jester cut
Answer:
2 pieces
Step-by-step explanation:
Given
[tex]Length = 1\frac{2}{3}m[/tex]
[tex]Pieces = \frac{3}{4}m[/tex]
Required
Determine the number of pieces
To do this, we simply divide the length of the wood by the length of each piece.
[tex]Number = \frac{Length}{Pieces}[/tex]
[tex]Number = 1\frac{2}{3}/\frac{3}{4}[/tex]
Convert fraction
[tex]Number = \frac{5}{3}/\frac{3}{4}[/tex]
Change sign to *
[tex]Number = \frac{5}{3}*\frac{4}{3}[/tex]
[tex]Number = \frac{20}{9}[/tex]
[tex]Number = 2.2222[/tex]
[tex]Number = 2[/tex] (approximated)

Allan writes down n positive integers so that the sum of those numbers is 23. When he multiples those numbers, he gets the maximum result. List all of the n positive integers that Allan has written.
Answer:
3, 3, 3, 3, 3, 3, 3, 2Step-by-step explanation:
To get maximum product we need to optimize how we break down the numbers
Its obvious we don't want number 1 to be used as it won't change the product
Also we don't want to use big numbers, we can have four 5's instead of two 10's as it would give greater product, 5*5 > 10
What is best number?
2 and 3 are the smallest, 4 can be written as two 2's5 = 2+ 3 and 2*3 = 6, so it is better to use 2's and 3's instead of 56 = 2+2+2, 2^3 = 8 and 6 = 3+ 3, 3^2 = 9, so it is better to use two 3's for 67 = 2+2+3, 2*2*3= 12, again 2's and 3's make greater productSo the best is to break the number down to 2's and 3's
23 = 2*10 + 3 ⇒ 2^10*3 = 307223 = 3*7 + 2 ⇒ 3^7*2 = 4374As we see the maximum product we can get is 4374 with seven 3's and one 2.
Hence the numbers are:

Ricardo ran four miles in 31 minutes. It took him 6.25 minutes to run the first mile. Ricardo ran the remaining miles at a slow and steady speed. How long did it take him to run each of the last three miles?
Answer:
8.25 minutes
Step-by-step explanation:
31 minutes-6.25 minutes=24.75 remaining miutes between the last 3 miles so then you take 24.75 minutes÷ 3 miles remaining= 8.25 minutes each last 3 miles
Mr. Chu is slicing for cantaloupes his for his class there are 24 students in the class if Mr. Chu cuts the cantaloupes to make a equal portion for each student how many of the whole cantaloupe what each student get
Answer:
3 cantaloupes
Step-by-step explanation:
Since there are 24 students if you divide 24 by 3 it equals 8 so eat cantaloupe should be cut into 8 pieces. So, Mr.chu should buy 3 cantaloupes and cut each of the cantaloups in 8 equivalent slices for the students.

Answer:
B
Step-by-step explanation:
∠ACE and ∠ECB form a straight angle whose sum = 180°, hence
2x + 2 + 5x + 3 = 180
7x + 5 = 180 ( subtract 5 from both sides )
7x = 175 ( divide both sides by 7 )
x = 25 → C

6. You want to go to the movies. A ticket for a movie
cost $10.90. There is a student discount for 20% off
with a student ID. The tax rate charged is 5.75%.
What is the sale price of your ticket? Explain how you
arrived at your answer.
Answer: I do not know
Step-by-step explanation:
Answer: 9.22 (This is rounded)
Step-by-step explanation:
20% off of 10.90 is 2.18. So, you subtract that from 10.90 and you get 8.72. Then, you find the tax rate which is 0.5014. When you round it, you should get 0.50. After that, you add it to 8.72 since it’s the tax. That then gets you 9.22.
