y varies inversely as x. When x=10, y=20. Find y when x=50
Answer:
y=100
Step-by-step explanation:
You can solve this by comparing the ratio.
The first set is 10:20 or 1:2 when simplified.
This can then be applied to the second set. If x=50, then 50 times 2 will give you the answer of 100.

To get the 10% discount, a shopper must spend at least $200
so
Let
d ------> represent the spending (in dollars) of a shopper who gets the discount
therefore
The value of d must be greater than or equal to $200
i would say that d is greater

Which statements are true about the ordered pair (7, 19) and the system of equations?
The ordered pair (7, 19) is a solution to the first equation because it makes the first equation true.
The ordered pair (7, 19) is a solution to the second equation because it makes the second equation true.
The ordered pair (7, 19) is not a solution to the system because it makes at least one of the equations false.
The ordered pair (7, 19) is a solution to the system because it makes both equations true.
Answer:
(7,19) is a solution for only the first equation (2x-y= -5), so it is not a solution to the systemmmm

Two triangles A B C and D F G. A B is 5 inches. B C is 6 inches. A C is 7 inches. D F is 15 inches. F G is 18 inches. Angle B is congruent to angle F.
I believe the answer is 5/7=15/DG.
Please, do correct me if the answer seems wrong, thank you.
The proportion which can be used to describe the value of DG is
15 x 7 = 5 x DG
What are similar triangles?
Two triangles are said to be similar if their sides are proportional and their angles are equal.
Given data ,
The two triangles are ΔABC and ΔDFG are similar
Length of AB = 5 inches
Length of BC = 6 inches
Length of AC = 7 inches
Length of DF = 15 inches
Length of FG = 18 inches
And , ∠B is congruent to ∠F
The two triangles are similar , so the ratio of
AB / DF = BC / FG = AC / DG
Therefore , 5 / 15 = 7 / DG
DG = 21 inches
Hence , the proportion used to find the value of DG is 15 x 7 = 5 x DG

It takes Sam 3 hours to rake leaves, but if Laura helps, it takes 2 hours. How long would it take Laura to rake the leaves on her own?
Answer:
6 hours
Step-by-step explanation:
Given that:
Time taken by Sam = 3 hours
Sam's rate = 1/3
Time taken : Sam + Laura = 2 hours
Sam's rate + Laura's rate = 1/2
Let time taken by Laura = x
1/3 + 1/x = 1/2
1/x = 1/2 - 1/3
1/x = (3 - 2) / 6
1/x = 1 /6
x = 6
Hencw, it will take 6 hours for Laura alone to rake leaves
