Question

If x is directly proportion to y and x1=5,y1=210 and x2 = 2, then find y2?

Answer 1

Answer:

44

Step-by-step explanation:

If x is directly proportion to y

x = ky( let k is constant)

5=k210

or k=5/210 =1/22

if x=2

2=1/22 y

y=44

Answer 2

Answer:

84

Step-by-step explanation:

As stated in the question X is directly proportional to Y

So,

Y2/X2=Y1/X1

Y2=(Y1/X1) *X2

Y2=(210/5)*2

Y2= 42*2

Y2=84
