Question

R(6 1/2)=5(6 1/2) - 3.5

Answer 1

The value of r in the equation r(61/2)=5(61/2)-3.5 is 4.88.

Given an equation r(61/2)=5(61/2)-3.5.

We are required to find the value of r in the equation.

Equation is like a relationship between two or more variable that are expressed in equal to form. The equation of two variables look like ax+by=c. It may be a linear equation, quadratic equation, cubic equation and many more depending on the powers of the variable present in that equation.

In our equation the variable is r.

The equation is given as:

r(61/2)=5(61/2)-3.5

r(61/2)=305/2-3.5

r(61/2)=(305-7)/2

r(61/2)=298/2

r=(298*2)/(2*61)

r=596/122

r=4.88

Hence the value of r in the equation r(61/2)=5(61/2)-3.5 is 4.88.
