Question

The variable x and y are inversely proportional to each other.When x =7,y=3,what is the value of t when y=21?solution

Answer 1

Answer:

The value of x is 1.

Step-by-step explanation:

Since x and y are inversely proportional to each other, the mathematical relationship between x and y can be expressed as x = k/y where k is the proportionality constant

x = k/y

k = xy

When x = 7, y = 3

k = 7×3 = 21

When y = 21

x = k/y = 21/21 = 1

Answer 2

Answer:

I'm guessing you meant X instead of T because there is no information about T.

21/3=7 so the ratio is 7 times more

7 x 7 = 49 so 49 is the answer
