Question

evaluate -y + (-z) + 7.99 where y= 1.46 and z = 3.82

Answer 1

First, substitute y=1.46 and z=3.82 into the expression:

-y + (-z) + 7.99
= -1.46 + (-3.82) + 7.99
= -1.46 - 3.82 + 7.99
= -5.28 + 7.99
= 2.71

Therefore, the value of the expression -y + (-z) + 7.99 when y=1.46 and z=3.82 is 2.71.
