Answer:
The value of x is 16.
Step-by-step explanation:
Given data:
3/4 = 12/r
The value of x = ?
Solution:
3/4 = 12/r
By multiplying 4 on both sides of equation:
= 3/4 × 4 = 12/r × 4
= 3 = 48/r
By cross multiplication:
= 3r = 48
By dividing 3 on both sides:
= 3r/3 = 48/3
= r = 16
The value of x = 16
Step-by-step explanation:
Here the value of x means the value of r. Because in equation r is unknown and in general mathematics x means an unknown value.
So by simplifying and solving the equation, r is equal to 16. And consequently x is equal to 16.
