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

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

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
