Kojo wants to be an author. To improve his writing skills, every day after school he writes 3 pages of a story he is working on. Kojo has been writing his story for days. He has a total of 81 pages completed.
Write an equation to describe this situation.
Answer:
days = pages / rate = 81 pages // 3 pages / day
Step-by-step explanation:
pages = 81 pages
rate = 3 pages / day
days = ?
days = pages / rate
days = 81 // 3 pages / day
days = 27 days.

Given: RT and PQ intersect at point S so that
RS = PS and ST = SQ.
Prove: RT = PQ
Step-by-step explanation:
substitution property :
we know that
RS + ST = PS + SQ
RS + ST = RT
PS + SQ = PQ
now we can use RT and PQ as substitutes in the first equation and we get
RT = PQ
Lucy is estimating the income levels of households in a specific zip code. She randomly calls 100 households and collects
information about their income levels. Which of the following is not true?
Select the correct answer below:
The average income level of all households in the zip code is a population parameter.
O The total income of the surveyed households is a sample statistic.
O The average income of the surveyed households is a sample data.
The surveyed households are considered a sample of the overall population of households living in the zip code.

The average income for the household that is surveyed should represent the sample data is not relevant.
The information that should be considered as follows:
The level of the income of the household represents the parameter of the population.The total income for the household that is surveyed represents the statistics of the sample.The household i.e. surveyed is relevant for the sample of the total population that lives in the zip code.Therefore we can conclude that the average income for the household that is surveyed should represent the sample data is not relevant.

7. Is the relationship between the temperature scales proportional?
Why or why not?
Answer:
By definition, Proportional relationships have the following form:
y=kxy=kx
Where "k" is the Constant of proportionality.
By definition the graph of a proportional relationship is a straight line that passes through the origin (Point (0,0)(0,0) ).
Knowing this and having the relationship provided in the exercise, you can identify from the table that when:
x=0x=0 , y=32y=32
Then, the line does not pass through the origin, so you can conclude that the relationship between the temperature scales is not proportional.

Determine whether the formula describes y as a function of x. Explain your reasoning. y= -3x^2-7x-6
Answer:
Step-by-step explanation:
This is the concept of algebra, a function is defined as a relationship whereby each input has one and only one single output.
In our expression;
y=-3x^2-7x-6
this can be written as:
f(x)=-3x^2-7x-6
such that, given x=0,1,2,....
f(0)=-6,
f(1)=-16
f(2)=-32
This implies that y is a function of x.

Joes account was 1 more than one half of Chandras account. The sum of their accounts was $751. Find the amount of Joes account
Answer:
251$
Step-by-step explanation:
Let's say x represents Joes's account.
And y represents Chandra.
Since Joses account was 1 more than one half of chandra, the amount for Joes would be x = 1/2*y + 1
Now we can just say y = Chandra's amount.
So x + y = 751
And x = 1/2*y + 1
We have a systems of equation, and just plug in 1/2*y + 1 for x.
1/2*y + 1 + y = 751
1/2*y + y = 750 (subtract both sides by 1)
distribute y so...
y(1/2 + 1) = 750
y = 750/1.5
y = 500
Remember, y is Chandra. So plug in 500 for y in Joses equation, so 1/2(500) +
is 250 +1 so 251.

Answer:Price of laptop A = $1220
Step-by-step explanation:
Sum of the price: A + B = 2185
Sum of the price: A + C = 2571
B : C = 5 : 7
B = 5/7 × C
So, replace the B:
A + 5/7 C = 2185
A + C = 2571
Eliminate by subtracting the first from the second: 2/7 C = 386
C = 1351
So, A = 2571 - 1351 = 1220

p = - 2
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, - 3) and (x₂, y₂ ) = (3, 7)
m = [tex]\frac{7-(-3)}{3-(-1)}[/tex] = [tex]\frac{7+3}{3+1}[/tex] = [tex]\frac{10}{4}[/tex] = [tex]\frac{5}{2}[/tex]
Parallel lines have equal slopes
Calculate the slope of the other 2 points and equate to [tex]\frac{5}{2}[/tex]
with (x₁, y₁ ) = (3, p) and (x₂, y₂ ) = (7, - 4p)
m = [tex]\frac{-4p-p}{7-3}[/tex] = [tex]\frac{-5p}{4}[/tex] = [tex]\frac{5}{2}[/tex] ( cross- multiply )
- 10p = 20 ( divide both sides by - 10 )
p = - 2

Point B is the midpoint of AC. AB=3x and AC=5x+21 . What is the value of AB?
First, let's write down what we know.
AB = 3x
AC = 5x+21
Since B is the midpoint, AB is half the length of AC. The sum of AB + AB is equal to the length of AC.
AB + AB = AC
Let's plug in our values.
3x + 3x = 5x + 21
Simplify the left side.
6x = 5x + 21
Subtract 5x from both sides.
x = 21
Now, let's plug in 21 for x in AB
AB = 3x = 3(21) = 63

The pet store had 2 cats, 3 dogs, and 1 hamster. How many animal legs did the pet store have?
Answer:
24 legs
Step-by-step explanation:
multiple the amount of cats, dogs and hamsters by 4 and add all three answers together and u get 24
Hey there! Here's your answer.
If you mean literal legs, as in the things you use to walk, the answer would be 24.
Explanation:
First, I added all the animals up.
2 + 3 + 1 = 6
Next, I multipled the answer of the last equation by 4 because each of these animals has 4 legs.
6 x 4 = 24
Finally, I got the answer of 24.
I hope this helps!
