Exercise 55 Page 701

To find the value of x, we should first gather all of the variable terms on one side of the equation and all of the constant terms on the other side using the Properties of Equality. In this case, we need to start by multiplying the equation by x and then use the Properties of Equality in order to isolate it.

336.4/x=π

MultEqn

LHS * x=RHS* x

336.4=π x

DivEqn

.LHS /π.=.RHS /π.

336.4/π=x

RearrangeEqn

Rearrange equation

x=336.4/π

Now, remembering that π is approximately 3.14 we can substitute it for π and evaluate x.

x=336.4/π

π ≈ 3.14

x≈336.4/3.14
