The common factor between 10 and 15 is 5.
5 goes into 10 twice and 15 three times.
[tex]\frac{15}{10}[/tex] ÷ [tex]\frac{5}{5} = \frac{2}{3}[/tex]

Six less than twice a number x is four
Answer:
2 x − 6
Explanation:
"Six less than.." means "Subtract 6 from".
Do not confuse this with "Six less..." which means "Subtract from 6".
Confusing, I know.
We know that "Double a number" means
2 x , where x is your mystery number.
Therefore, we have:
2 x − 6 , which translates to "6 less than 2x" or "6 less than twice a number"

what is 1+1
I NEED HELP
Answer:
2
Step-by-step explanation:
1+1
2
This question is so hard
Any number times one equals itself, and any number multiplied by two equals itself plus itself, so 1*2=2 and 1*2=1+1. The transitive property of equality states that if x=y and y=z then x=z. Since both 1+1 and 2 are equal to 1*2, they must be equal to each other, so 1+1=2.
The answer is 2

If you pay $7 for 3 tickets how much would 24 tickets cost?
Answer:
24 tickets would cost about $55.92
Step-by-step explanation:
To solve this equation I decided to figure out how much one ticket cost. I divided 7 by 3 and got 2.333333 I rounded that to one ticket costing $2.33. I then multiplied 2.33 by 24. 24 x 2.33= 55.92.
The reason I multiplied 24 by 2.33 is because the cost of one ticket is $2.33 so if I wanted to buy 24 tickets, I would have to multiply in order to find out the total cost.
I hope that this answer helped :D
Answer:
24 tickets would cost $56
Step-by-step explanation:
You would Convert it to a decimal by dividing the numerator by the denominator. 7/3*24=$56
3 tickets cost=$7
1 ticket cost= 7/3=$7/3

Point NN is located at (-2,-6)(−2,−6) on the coordinate plane. Point NN is reflected over the yy-axis to create point N'N ′ . Point N'N ′ is then reflected over the xx-axis to create point N''N ′′ . What ordered pair describes the location of N''?N ′′ ?
Given:
Coordinates of point N = (-2,-6)
Point N is reflected over the y-axis to create point N ′.
Point N' is then reflected over the x-axis to create point N''.
To find:
The ordered pair that describes the location of N''.
Solution:
The coordinates of point N are (-2,-6). Point N is reflected over the y-axis to create point N ′.
[tex](x,y)\to (-x,y)[/tex]
[tex]N(-2,-6)\to N'(2,-6)[/tex]
Point N' is then reflected over the x-axis to create point N''.
[tex](x,y)\to (x,-y)[/tex]
[tex]N'(2,-6)\to N''(2,6)[/tex]
Therefore, the ordered pair for point N'' is (2,6).
Answer:
(-6,2)
Notice that the xx-coordinate and the yy-coordinate change sign when LL is reflected over the xx-axis and then reflected over the yy-axis.
A slope field produces...
A. the graph of the general solution to the differential equation
B. the graph of the derivatives of the differential equation
Please explain. I am so confused on this.
It's A. B doesn't really make sense ("derivative of the differential equation" is somewhat nonsensical, "derivative of an equation" is not meaningful).
More to the point: Slope fields are used to visualize solutions to differential equations of the form
y' = f(x, y)
You take some point (x, y) and evaluate y' at the point. This gives the slope of the line tangent to the particular solution to the DE that passes through the point (x, y ).
Sample several points and evaluate y' at those points and you get several different slopes.
Simple example:
y' = x ² - y ² = (x + y ) (x - y )
Let's take the points (1, 1), (-1, 0), and (2, -2), at which we get slopes
y' = f (1, 1) = 0
y' = f (-1, 0) = 1
y' = f (2, -2) = 0
From here, you can get particular solutions that pass through a certain point by interpolating the slopes of the tangents to the solution. I've attached a slope field for the example here at the points listed above. (In the order red, green, black). Each light gray arrow in the background shows the slope of the tangent line.
If you're still unsure how the slope field is generated, I suggest looking up videos on the subject. The process is a bit difficult to describe without a dynamic visual aid.

Answer:
216mx meters
Step-by-step explanation:
m is in minutes so convert it in hours = 60m hrs
Speed is in metres per second, convert it in kilometers per hour= 18x/5
Now we’ve time and speed, put it in the formula
Distance = speed x time
= 18x/5 x 60m
= 216mx meters

I NEED ASAP DUE IN 20 MINS
Answer:
y = 45 / 2x + 50
Step-by-step explanation:
The best equation for the line of the best fit would be y = 45 / 2x + 50.
The slope would be 45 / 2 and the y-intercept would be ( 0 , 50 ).
I used the points, ( 0 , 50 ) and ( 4 , 140 ) to get the equation, slope, and the y-intercept.
I used those points because they were the most accurate ones that I know for now.
Also, remember the formula is, "y = mx + b."
what's the simplified version?
Answer:
D) [tex]x^{12}[/tex]
Step-by-step explanation:
Note that all the base are the same (the variable x). You are multiplying the three like terms together. Simply add the powers together:
[tex]x^{3} * x^{4} * x^{5} = x^{3 + 4 + 5} = x^{12}[/tex]
D) [tex]x^{12}[/tex] is your answer.

Write the equation of the line, in slope intercept form, that goes through the points (6,4) and (-3,-5)
Answer:
y = x - 2
Step-by-step explanation:
Find the slope using rise over run
(y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(-5 - 4) / (-3 - 6)
-9 / -9
= 1
Using y = mx + b, plug in the slope and a point to solve for b:
y = mx + b
4 = 1(6) + b
4 = 6 + b
-2 = b
Plug in the slope and b to y = mx + b
y = 1x - 2
y = x - 2
So, the equation of the line is y = x - 2
