Question

X-4/8 при x=12 16-2a/8 при a=3

Answer 1

1)8/8--1. 2)10/8--1/2/8

Answer 2

To evaluate the given expressions, simply substitute the given values for the variables and perform the calculations:

1. For the expression X-4/8 when x=12: X = 12 X-4/8 = 12 - 4/8 = 12 - 0.5 = 11.5

2. For the expression 16-2a/8 when a=3: a = 3 16 - 2a/8 = 16 - 2(3)/8 = 16 - 6/8 = 16 - 0.75 = 15.25

So, the values of the expressions are:

1. X-4/8 (when x=12) = 11.5
2. 16-2a/8 (when a=3) = 15.25
