Question

find the value of the a, B, c, and d, if x and y in direct proportion

Answer 1

Answer:

a = 4

b = 12

c = 22.5

d = 18

Step-by-step explanation:

x is directly proportional to y

so we can write

a/6 = 12/18

=> a/6 = 2/3

=> 3*a = 2*6

=> 3a = 12

=> a = 12/3

=> a = 4

8/b = 2/3

=> 3*8 = 2b

=> b = 12

15/c = 2/3

=> 45 = 2c

=> c = 22.5

d/27 = 2/3

=> 27 * 2 = 3d

=>27/3*2 = d

=> d = 18
