Suppose that r = 3 , t = − 3 , u = 0 , and w = − 6 . Evaluate each of the following expressions.

Question

6 – __t__

r⋅w

Answer 1

simple substitution yields:

6 - (-3)/[3*(-6)]

the denominator of the fraction becomes -18

and the numerator is -3.

our simplified result is:

6 - 3/18 = 6 - 1/6 = 35/6 = 5.166666667 :)

Answer 2

Suppose that r = 3 , t = − 3 , u = 0 , and w = − 6 . Evaluate each of the following expressions.

6 – __t__

r⋅w

6- (-3 / (3)(-6))= 6 - (-1/6)=6+1/6 = 37/6
