Question

the variable x varies directly as y and x =100 when y=25.what is the value of x when y is 15​

Answer 1

Answer:

60

Step-by-step explanation:

if x varies directly as y then

if x=100

and y=25

dividing both by 25 we get.

x=4

y=1

so for y to be 15

multiply 15 to both of them

x= 4×15 =60

y=1×15 = 15

therefore at y=15 x= 60

Answer 2

x+y = 100

if, y = 25

then x+y = 100

x + 25 = 100

x = 100 - 25

x = 75
