Answer:
(x^2 - 5x^2 + 4x) / 2x + 8
Step-by-step explanation:
(x^2 - 16) / 2x + 8 * (x^3 - 2x^2 + x) / (x^2 + 3x -4)
(x^5 - 2x^4 - 15x^3 + 32x^2 -16x) / 2(x - 1)(x + 4)(x + 4)
x(x-1)(x-1)(x+4)(x-4) / 2(x - 1)(x + 4)(x + 4)
(x^3 -5x^2 +4x) / 2x + 8

A boat travel 448 km using 112 litres of gasoline.How far can the boat travel using 1 litre of gasoline
Divide total distance by total liters used.
448 km / 112 liters = 4 km per liter.
Using 1 liter of gas the boat can travel 4 km.
Answer:
1 litre = 4 km
Step-by-step explanation:
448/112 = 4/1
Cross multiplication, 448 x 1 divided by 112 = 4
-5√112
I have to solve this using perfect square factors, is anyone familiar with those?
Answer:
-20√7
Step-by-step explanation:
Here. we want to write this in the simpler form
we can have 112 as; 16 * 7
√112 = √(16*7)
√112 = 4 √7
so, we have
-5 * 4 √(7 = -20 √7

Jessica is returning home from a trip. The function d(t)=458-60t models the distance, in miles, that Jessica is from her house t hours after she began returning home. How far is Jessica from her home 5 minutes after she began returning home?
A.
5 miles
B.
158 miles
C.
300 miles
D.
453 miles
Answer: D. 453 miles .
Step-by-step explanation:
Given: The function [tex]d(t)=458-60t[/tex] models the distance, in miles, that Jessica is from her house t hours after she began returning home.
At t = 5 minutes = [tex]\dfrac{5}{60}[/tex] hour [1 hour = 60 minutes],
Distance covered by Jessica in 5 minutes = [tex]d(\dfrac{5}{60})=458-60(\dfrac{5}{60})[/tex]
[tex]=458-5=453\ miles[/tex]
Jessica is 453 miles from her home after 5 minutes she began returning home.
Hence, the correct option is D. 453 miles .

Use the given x and y values to write a direct variation
equation. Enter your answer in the form y = kx.
x = 5, y = 50
The form is y = kx
Replace y and x:
50 = k(5)
Solve for k by dividing both sides by 5
K = 10
PLEASE HELP! A positive number is 1/3 of another number. The sum of the numbers is five less than the square of the larger number. Find the numbers. PLEASE SHOW WORK Thanks!
Answer: The numbers are 1 and 3.
Step-by-step explanation:
Let x = smaller number , y= larger number.
As per given,
[tex]x=\dfrac{y}{3}[/tex] ...(i)
[tex]x+y=y^2-5[/tex] ...(ii)
Put value of x from (i) in (ii)
[tex]\dfrac{y}{3}+y=y^2-5\\\\\Rightarrow\ \dfrac43y=y^2-5\\\\\Rightarrow\ 3y^2-4y-15=0\\\\\Rightarrow\ 3y^2-9y+5y-15=0\\\\\Rightarrow\ 3y(y-3)+5(y-3)=0\\\\\Rightarrow\ (y-3)(3y+5)=0\\\\\Rightarrow\ y=3 \ \ or\ y=\dfrac{-5}{3}[/tex]
Since numbers are positive , so y=3 is correct.
And x will be 1 [from (i)]
Hence, the numbers are 1 and 3.

Explain a line graph in your own words
Answer:
A line graph (also known as a line plot or line chart) is a graph which uses lines to connect individual data points that display quantitative values over a specified time interval. Line graphs use data point "markers" that are connected by straight lines to aid in visualization.

Paul buys 5 bags of chips and 9 bags of pretzels for $16.95. Ian buys 1 bag of chips and 1 bag of pretzels for $2.55. Find the cost of one bag of chips and one bag of pretzels.
Answer: The cost of one bag of chips is $1.5 and cost of one bag of pretzels is $1.05.
Step-by-step explanation:
Let x= Cost of one bag of chips
y= Cost of one bag of pretzels.
As per given, we have
5x+9y=16.95 ...(i)
x+y=2.55 ...(ii)
Multiply 5 to (ii), we get
5x+5y=12.75 ...(iii)
Eliminate (iii) from (i), we get
[tex]4y=4.2\\\\\Rightarrow\ y=1.05[/tex]
Put value of y in (ii), we get
[tex]x+1.05=2.55\\\\\Rightarrow\ x=2.55-1.05=1.5[/tex]
Hence, the cost of one bag of chips is $1.5 and cost of one bag of pretzels is $1.05.

Answer:
x = 35.1 degrees
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adj/ hyp
cos x = 27/33
Take the inverse cos of each side
cos ^-1 ( cos x) = cos ^-1(27/33)
x =35.09680123
To the nearest tenth
x = 35.1 degrees
Answer:
x=35.1
Step-by-step explanation:
cos(x)=[tex]\frac{27^{2}+33^{2}-360 }{2(27)(33)}[/tex]
x=35.1(correct to the nearest tenth)

Find the Measure of angle O
(see image)
Only real answers, please
Answer:
From the given figure we can see that :---
MN||PO, MN=PO and MP=NO
Therefore, angle M=angle N (adjacent sides of the trapezoid)
[tex](8x - 16) = (6x + 20) \\ 2x = 36 \\ \boxed{x = 18}[/tex]
angle M=angle N= (6×18)+20=108+20 =128°
angle O =(180°-128°)=52°
Hence, angle O is 52°.It took a car 4 days to travel 2686 miles. What was this car's average speed, in miles per hour? (round to the nearest mile per hour)
Answer:
28
Step-by-step explanation:
Well we know that in a day there are 24 hrs so in 4 days there will be 96 hrs
so the car travelled 2686 miles in 96 hours
2686/96= 27.9791666667
So the car's average speed is about 28
