15. in each of the following, Y is inversely proportional to X. find the values indicated 1.if Y=10 when X=2/5 ,what is the equation of the variation? brainliest best answer
Answer:
Given, y is inversely proportional to x
or y∝x−1
this is if and only if
y∝1x
⇔
y=1xk
Also, we know that if y=6 when x=4
then
6=14k
⇔ multiply both sides by 4
24=k this is our constant of proportionality
⇒
this gives us our formula
y=24x
Then consider when y=8
then
8=24x
⇔ multiply both sides by x
8x=24
⇔ divide both sides by 8
x=3

16. Directions: Find for the value of (y) in following proportions.21. 42:y = 30:90 ( direct proportion )22. 36:10 = y:60 ( inverse proportion )23. 4y:24 = 30:4 ( direct proportion )24. 6:6y = 50:90 ( direct proportion )25. 24:10y = 54:130 ( inverse proportion )I hope you can help me with this problem
• Two quantities x and y are said to be in direct proportion if they
increase or decrease together in such a manner that the ratio of
their corresponding values remains constant. That is, x = k where
k is a positive number, if x and y are in direct proportion or vary
directly. In case of direct proportion, if y1, y2 are the values of y
corresponding to the values x1, x2 of x respectively, then 1 2
1 2
x x
y y .
• Two quantities x and y are said to be in inverse proportion if an
increase in x causes a proportional decrease in y and vice-versa, in
such a manner that the product of their corresponding values
remains constant. That is, xy = k where k is a positive number, if x
and y are in inverse proportion. In this case, if y1, y2 are the values
of y corresponding to the values x1, x2 of x respectively, then x1 y1=
x2 y2 or
x y
x y
1 1
2 2
• Quantities increasing or decreasing together need not always be
in direct proportion, same in the case of inverse proportion.
• When two quantities x and y are in direct proportion (or vary directly),
they are written as x ∝ y. Symbol “∝” stands for ‘is proportional to’.

Answer:
A) y = 12
B) y = 22
C) y = 3
D) y = 15
Step by step solution:
A)
y = 28
21 49
49y = (21)(28)
49y = 588
49y = 588
49 49
y = 12
B)
y + 5 = 9
12 4
4(y + 5) = (12)(9)
4y + 20 = 108
4y = 108 – 20
4y = 88
4y = 88
4 4
y = 22
C)
y + 4 = 7y
6 18
18(y + 4) = 7y(6)
18y + 72 = 42y
72 = 42y – 18y
72 = 24y
72 = 24y
24 24
3 = y
D)
2y – 3 = 3y – 7
3 2
2y – 3(2) = 3y – 7(3)
2y – 6 = 3y – 21
-6 + 21 = 3y – 2y
15 = y

Answer:
1.
42:y = 30:90
30y = 90 x 42 = 3780
y = 3780 / 30
y = 126
2.
36:10 = y:60
10y = 60 x 36 = 2160
y = 2160 / 10
y = 216
3.
4y:24 = 30:4
16y = 30 x 24 = 720
y = 720 / 16
y = 45
4 x 45 = 180
4.
6:6y = 50:90
300y = 90 x 6 = 540
y = 540 / 300
y = 1.8
6 x 1.8 = 10.8
5.
54:10y = 54:130
540y = 130 x 54 = 7020
y = 7020 / 540
y = 13
10 x 13 = 130

29. 2. Find the value of y in the following proportions.a.y/21=28/49 b.y+5/12=9/4
Answer:
a.
y/21 = 28/49
cross multiply
49y = 588
divide both sides by 49
y = 12
b.
y+5/12 = 9/4
multiply both sides by 12
y+5 = (9/4)(12)
y+5 = 108/4
y+5 = 27
y = 27-5
y = 22
Answer:
a. y = 12
b. y = 22
Step-by-step explanation:
[tex]a. \: \frac{y}{21} = \frac{28}{49} [/tex]
multiply 21 on both sides
[tex]21 \times \frac{y}{21} = \frac{28}{49} \times 21[/tex]
[tex]y = \frac{28 \times 21}{49} [/tex]
[tex]y = \frac{588}{49} [/tex]
a. y = 12
[tex]b. \: \frac{y + 5}{12} = \frac{9}{4} [/tex]
multiply 4 on both sides
[tex]4 \times \frac{y + 5}{12} = \frac{9}{4} \times 4[/tex]
[tex]\frac{4(y + 5)}{12} = 9[/tex]
multiply 12 on both sides
[tex]12 \times \frac{4(y + 5)}{12} = 9 \times 12[/tex]
[tex]4(y + 5) = 108[/tex]
Distribute 4 inside
[tex]4y + 20 = 108[/tex]
transpose 20
[tex]4y = 108 - 20[/tex]
[tex]4y = 88[/tex]
divide 4 on both sides
[tex]y = 22[/tex]
