If varies inversely as . It is known that = 10 when = 3, find the value of when = 5.
Answer:
y = 6
Step-by-step explanation:
If x varies inversely proportional as y.
[tex]x=\dfrac{k}{y}[/tex], k is constant of proportionality
or
k = xy
When x = 3 and y = 10
k = 3×10
k = 30
Put x = 5,
[tex]y=\dfrac{k}{x}\\\\y=\dfrac{30}{5}\\\\y=6[/tex]
So, the value of y is 6 when x is 5.

1. SOCCER Suppose a youth soccer field has a
perimeter of 320 yards and its length measures 40
yards more than its width. Ms. Hughey asks her
players to determine the length and width of their
field. She gives them the following system of
equations to represent the situation. Use elimination to
solve the system to find the length and width of the
field.
2L + 2W=320
L - W = 40
Answer:
L = 100
W = 60
Step-by-step explanation:
2L + 2W = 320
-2L + 2W = -80
4W = 240
W = 60
L - W = 40
L - 60 = 40
L = 100

Which graph best represents the equation y= 2x
Answer:
The answer is H.
Step-by-step explanation:
There is no "b" in this y = mx + b, so it has to go through zero, eliminating the bottom two. If we insert y = 2(1), the point should be at (1, 2), and if when looking at the possible answers, we can go with letter H.
If 7x−7y=4 is a true equation, what would be the value of
5(7x−7y)
Answer:
20
Step-by-step explanation:
Since that is a true equation, you can substitute 7x - 7 y for 4 and simplify.
5(7x - 7y)
5(4)

The price of a washing machine was decreased by 20% to £640.
What was the price before the decrease?
Answer:
£800
Step-by-step explanation:
Find 1% of the washing machine price using the percentage and the price of the washing machine after it decreased to help you.
100 - 20 = 80
80% = 640
1% = 640 ÷ 80 = 8
Now, since they asked the price before it decreased, they are asking for the full price.
100% = 8 x 100 = 800

What is the diameter of the circle 18in?
i'm sending a lot there 14 i've been sick
Answer:
linear
Step-by-step explanation:
feel better
Answer:
Linear is that y=ax
And a=slope=(y-y)/(x-x)
a=(3-1)/(1-0)=2/1=2
If it is linear then take point A(3,10) and replace it in the equation y=2x
Then 10 is not equal to 2(3) which is 6
Then the answer is nonlinear function
I hope it is clear now

Step-by-step explanation:
Beth and Kayla are selling flower bulbs for a school fundraiser. Customers can buy packages of tulip bulbs and bags of daffodil bulbs. Beth sold 7 packages of tulip bulbs and 9 bags of daffodil bulbs for a total of $269. Kayla sold 7 packages of tulip bulbs and 2 bags of daffodil bulbs for a total of $136. Find the cost each of one package of tulip bulbs and one bag of daffodil bulbs.
Answer:
the cost each of one package of tulip bulbs and one bag of daffodil bulbs is $14 and $19 respectively
Step-by-step explanation:
The computation of the cost of each of one tulip package bulbs and one bag of daffodil bulbs is shown below:
Let us assume the tulip bulbs be x
And, the daffodil bulbs be y
According to the question
7x + 9y = $269.........(1)
7x + 2y = $136..........(2)
Now subtract equation 2 from equation 1
7y = $133
y = $19
Now put the value of y in any of the above equation
7x + 9($19) = $269
7x = $269 - $171
x = $14
Hence, the cost each of one package of tulip bulbs and one bag of daffodil bulbs is $14 and $19 respectively
