A traveler is walking on a moving walkway in an airport. The traveler must walk back on the walkway to get a bag he forgot. The traveler's ground speed is 1 fts against the walkway and 5 ft/s with the walkway. What is the traveler's speed off the walkway? What is the speed of the moving walkway? The traveler's speed off the walkway is ft/s.
Answer: here is your answer
Step-by-step explanation:
You can put this solution on YOUR website!
+t+ = traveler's speed in ft/sec
+w+ = walkway's speed in ft/sec
given:
+t+-+w+=+2+
+t+%2B+w+=+6+
-------------
Add the equations
+2t+=+8+
+t+=+4+
and
+t+%2B+w+=+6+
+4+%2B+w+=+6+
+w+=+2+
The traveler's speed off the walkway is 4 ft/sec
The speed of the moving walkway is 2 ft/sec

Please do elimination method 2x-9y=-36
-14x+18y=-18
Answer:
The solution to the system of equations will be:
[tex]x=9,\:y=6[/tex]
Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}2x-9y=-36\\ -14x+18y=-18\end{bmatrix}[/tex]
Multiply 2x-9y=-36 by 7
[tex]14x-63y=-252[/tex]
so the system of equations becomes
[tex]\begin{bmatrix}14x-63y=-252\\ -14x+18y=-18\end{bmatrix}[/tex]
Adding both equations
[tex]-14x+18y=-18[/tex]
[tex]+[/tex]
[tex]\underline{14x-63y=-252}[/tex]
[tex]-45y=-270[/tex]
solve -45y = -270 for y
[tex]-45y=-270[/tex]
divide both sides by -45
[tex]\frac{-45y}{-45}=\frac{-270}{-45}[/tex]
Simplify
[tex]y=6[/tex]
For 14x-63y = -270 plug in y = 6
[tex]14x-63\cdot \:6=-252[/tex]
[tex]14x-378=-252[/tex]
Add 378 to both sides
[tex]14x-378+378=-252+378[/tex]
Simplify
[tex]14x=126[/tex]
Divide both sides by 14
[tex]\frac{14x}{14}=\frac{126}{14}[/tex]
Simplify
[tex]x=9[/tex]
Therefore, the solution to the system of equations will be:
[tex]x=9,\:y=6[/tex]

How many solutions are in the graph
A. One solution
B. Two solutions
C. No solutions
D. Infinitely many solutions
Answer:
Infinite Many Solutions
Step-by-step explanation:
If I am correct the two lines are overlapping each other in more than one place so that means there are infinitely many solutions. Also, there can be no " two solutions" for this type of equation. There can only be one solution, no solution, or infinitely many solutions.

Sheleah and her family are planning a trip from Los Angeles, California to Melbourne, Australia. While booking her family's plane tickets, she notices on the itinerary that the airline is offering a sixteen hour straight flight from Los Angeles to Melbourne on a Boeing 747-8 Intercontinental Jet. In an effort to learn more about the capabilities of the Jet, Sheleah does a little research and stumbles upon the following graph and facts about the Jet's gasoline consumption.
GRAPH IN SCREENSHOT
The Boeing 747-8 Intercontinental Jet can carry approximately 422,000 gallons of gasoline, making it possible for the jet to travel 14,430 kilometers before needing to refuel.
Using the graph, approximate the Jet's average gas consumption, in gallons per hour, during the sixteen hour flight from Los Angeles, California to Melbourne, Australia. In your final answer, include all of your calculations.
26375
On the graph, it tells you how much fuel is left after 2 hours of the journey.
If we take 422,000 and subtract 369,250 from it we get 52,750. However, this is how much gas is used in 2 hours, so to find one hour we need to divide by 2, getting us 26,375.
Therefore, the Jet uses 26,375 gallons per hour during the 16 hour trip from Los Angeles, CA to Melbourne, Australia.

The formula for the volume of a rectangular prism is V = lwh. What is the formula when solved for w?
Answer:
w=V/Ih
Step-by-step explanation:
The formula for the volume of a rectangular prism is given as V = lwh.
✓ we are required to solve for "w" and this can be done by making "w" subject of the formula.
w=V/Ih
Hence, formula for " w" is w=V/Ih
Evaluate y = -4(5)* for x = 2
The value of the function at x = 2 is -100
Exponential equationThey are written in the form y = ab^x
Given the exponential function y = -4(5)^x
IF the value of x is 2, hence the expression becomes:
y = -4(5)^2
y = -4(25)
y = -100
Hence the value of the function at x = 2 is -100
