Answer:
When we subtract the second equation x-2y=9 from the first equation 4x-2y=-2, we get the value of x = 11/5.
Therefore, the required result is:
x = 11/5
Step-by-step explanation:
Given
The first equation
[tex]-4x-2y=-2[/tex]
The second equation
[tex]x-2y=9[/tex]
Let us subtract the second equation from the first equation
[tex]-4x-2y=-2[/tex]
[tex]-[/tex]
[tex]\:\underline{x-2y=9}[/tex]
[tex]-4x - 2y - (x - 2y) = -2 - 9[/tex]
[tex]-4x -2y -x + 2y = -2-9[/tex]
[tex]-5x = -11[/tex]
divide both sides by -5
[tex]\frac{-5x}{-5}=\frac{-11}{-5}[/tex]
Simplify
[tex]x=\frac{11}{5}[/tex]
Thus, when we subtract the second equation x-2y=9 from the first equation 4x-2y=-2, we get the value of x = 11/5.
Therefore, the required result is:
x = 11/5

Answer:
slope = 10/1
Step-by-step explanation:
slope is the vertical rise over the horizontal rise
if you select two points on the line -- I used (10, 0) and (20, 20) -- and subtract the y-values you will get the vertical rise (20 - 0 = 20); if you now subtract the x-values (20 - 10 = 10) you will get the horizontal rise
so, 20/10 or 10/1
if you go from point (10, 0) to (20, 20) then you go up by 10 and over to the right by 1

if i walk 120 meters per minute slower than i cycle. my cycling speed is 3 times faster than my walking. What is my walking speed. meters per minute
Answer:
His walking speed is 60 meters per minute.
Step-by-step explanation:
Given that the person walks 120 meters per minute slower than he cycles, and his cycling speed is 3 times faster than his walking, in order to known his walking speed in meter per minute, the following logical reasoning has to be made:
The person walks 120 meters per minute slower than he rides a bicycle, and in turn, rides a bicycle three times faster than he walks. Therefore, those 120 meters per minute is 2/3 of his speed on a bicycle, which makes up the remaining third with the speed at which he walks. Thus, since 120/2 is 60, and 60 x 3 is 180, the person walks at 60 meters per minute, and bicycles at 180 meters per minute.

It’s due tonight I would appreciate the help
Answer:
-1, 4, 6, 8
k<9
Step-by-step explanation:
Two ways to do this
One is to substitute the values in for k and then see if the inequality is still true.
-1, 4, 6, 8, when substituted in for k and then multiplied by 5, will be less then 45.
9, however, does not work because 9 times 5 is 45, which makes the inequality untrue. So, k has to be less than 9.
The faster, more mathematical way is to divide both sides by 5. 5 divided by 5 is 1 and 45 divided by 5 is 9, so the new inequality would be k<9.
What is the difference between the greatest and the smallest rational numbers
given below?
7/15,11/20,2/5,12/25
Answer:
The difference between the greatest and smallest rational number [tex]=\frac{3}{20}[/tex]
Step-by-step explanation:
Step(i):-
Given that the rational numbers
[tex]\frac{7}{15} , \frac{11}{20} ,\frac{2}{5} ,\frac{12}{25}[/tex]
we have to find that the difference between the greatest and the smallest rational numbers
solution:-
The greatest rational number = [tex]\frac{11}{20}[/tex]
Convert into decimal = 0.55
The smallest rational number = [tex]\frac{2}{5}[/tex]
Convert into decimal = 0.4
The difference between the greatest and smallest rational number
[tex]= \frac{11}{20} - \frac{2}{5}[/tex]
= [tex]\frac{11-8}{20}[/tex]
[tex]=\frac{3}{20}[/tex]
Final answer:-
The difference between the greatest and smallest rational number [tex]=\frac{3}{20}[/tex]
