Answer:
The coordinates of point B is
( 7 , 3)Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]
where
(x1 , y1) and (x2 , y2) are the points
Let the coordinates of B be ( x , y)
From the question the midpoint is ( 0 , 4) and A is (-7 , 5)
So we have
[tex](0 \: , \: 4) = ( \frac{ - 7 + x}{2} , \: \frac{5 + y}{2} )[/tex]
Next we compare the x and y coordinates of the midpoint to the x and y coordinates on the right hand side to find the missing coordinates
That's we equate them
So we have
For x[tex]0 = \frac{ - 7 + x}{2} \\ - 7 + x = 0 \\ \\ x = 7[/tex]
For y[tex]4 = \frac{5 + y}{2} \\ 8 = 5 + y \\ y = 8 - 5 \\ \\ y = 3[/tex]
So we have
x = 7 , y = 3
So the coordinates of point B is

Hey there!
[tex]Answer:\boxed{x=\frac{4}{2y-z}}[/tex]
[tex]Explanation:[/tex]
[tex]2xy-xz=4[/tex] Solve for X
x(2y - z) Factor out the variable x
x(2y - z)/2y - z = 4/2y - z Divide both sides by 2y - z
x = 4\2y - z

A girl studied for 5 2/3 hours daily. She devotes 2 4/2 hours of her time for science and mathematics. How much time does she devote for other subjects?
Given :
Number of hours studied daily , [tex]T=5\dfrac{2}{3}[/tex] .
Time given for science and mathematics is , [tex]t=2\dfrac{4}{2}[/tex] .
To Find :
How much time does she devote for other subjects .
Solution :
Let , time devote for other student is x .
So , Time left for other subject = Total time - Time taken by science and mathematics .
[tex]x=T-t\\\\x=5\dfrac{2}{3}-2\dfrac{4}{2}\\\\x=\dfrac{(5\times 3)+2}{3}- \dfrac{(2\times 2 )+4}{2}\\\\x=\dfrac{17}{3}-4\\\\x=\dfrac{17-(4\times 3)}{3}\\\\x=\dfrac{5}{3}=1\dfrac{2}{3}[/tex]
Therefore , time devote for other subject is [tex]1\dfrac{2}{3}[/tex] hours .
Hence , this is the required solution .

A gamestop you can buy a xbox one foe 150.00 and each game to go with it would cost 24.00 or you can buy a playstation 4 for 180.00 abd esch game for 20.00
Answer:
Let's write two linear equations:
For the Xbox, we have:
Price per console (you pay it only once) = $150.
Price per game = $24
Then, the total price if you buy x games, you have:
P1(x) = $150 + $24*x
For the Playstation we have:
Price per console (again yo pay it only once) = $180
Price per game = $20
So if you buy x games, the total price is:
P2(x) = $180 + $20*x.
Now, we can find the number x such that both prices are equal
P1(x) = P2(x)
$150 + $24*x = $180 + $20*x.
let's solve this for x.
$24*x - $20*x = $180 - $150
$4*x = $30
x = $30/$4 = 7.5
What does this mean?
If you buy less than 7.5 games (7 or less) then the Xbox will be cheaper, because the y-intercept is smaller.
If you buy more than 7.5 games (8 or more) then the Playstation will be cheaper, because the price per game is smaller.

you have $55 in your bank account each week you plan to deposit $7 from your allowance and $25 from your paycheck. the equation b = 55+(25+7)w gives me je amount b in your account after w weeks. how many weeks from now will you have $270 in your bank account?
Answer:
7 weeks
Step-by-step explanation:
Answer: The answer is 3.10
Step-by-step explanation: Fisrt of all you add 25+7 which gives you 32. Add 32 and 55, gives you 87. You need to figure out w and b is 270. So 270 divided by 87 is 3.10. So you need 3.10 weeks.

15 less than a number S is three more than 9 times a number T. Solve for S
Answer:
s = 9t + 18
Explanation:
Set up your equation
s - 15 = 9t + 3
Now get s by itself by adding 15 to both sides
s + 0 = 9t + 3 + 15
s = 9t + 18
If you know the value of t, plug that into the equation to solve further.

Hannah took six quizzes in math. She scored 4 twice, 6 once, and 8 three times. What ja Hannah’s average for the six math quizzes?
Answer:
Option H. 6⅓
Step-by-step explanation:
Let X be the score.
Let F be the number of scores (i.e the frequency)
From the question given above, the following data were obtained from:
X >>>>>>>>> F
4 >>>>>>>>> 2
6 >>>>>>>>> 1
8 >>>>>>>>> 3
Thus, we can obtain the average as follow:
X >>>>>>>>> F >>>>>>> FX
4 >>>>>>>>> 2 >>>>>>> 8
6 >>>>>>>>> 1 >>>>>>> 6
8 >>>>>>>>> 3 >>>>>>> 24
Summation (FX) = 8 + 6 + 24
Summation (FX) = 38
Summation (F) = 2 + 1 + 3 = 6
The average = summation (FX) /Summation F
The average = 38/6
The average = 6⅓
Therefore, Hannah's average for the six math quizzes is 6⅓.

Samantha claims 3/5 is an integer is she correct?
Answer:
no
Step-by-step explanation:
because integers are positive and negative numbers
Answer:
She is not correct
Step-by-step explanation:
This is the answer because:
1) We know that an integer is either a negative or positive number which has no fractional components/ no relation to fractions.
2) This means that an integer should not be expressed in the x/y form, also known as the fraction form.
3) Integers should always be a whole number that is negative or positive. An integer should never be a "part" of a number.
Therefore, 3/5 in not an integer

Jesse runs a 26-mile race in 5 hours. LJ runs a 15-mile race in 2 hours. Who runs at a slower rate?
Answer: Jesse
because i guess i divided the number you could do it however 15 divided by 2 = 7.5 and 26 divided by 5 = 5.2
Answer:
Jesse is the slower rate.
Step-by-step explanation:
The slower rate is going to be determined by the distance divided by the time.
Jesse: 26 / 5 = 5.2 miles / hour
LJ: 15 / 2 = 7.5 miles / hour
Jesse is the slower rate.
