Answer 16.

Step-by-step explanation:

First you replace the xs with 1/2

(√2•1/2+3)/(6•1/2-5)

Then you solve the multiplications

2•1/2=1

6•1/2=3

Now write them in

(√1+3)/(3-5)

Simplify

(√4)(-2)

Root of 4 equals to

2/-2

And the answer is -1

Answer 17:

Replace x with 8

1/2•8^2-(1/4•8+3)

Solve parenthesis, multiplication first

1/2•8^2-(2+3)

1/2•8^2-(5)

1/2•8^2-5

Solve the 8^2 and the 1/2

1/2•64-5

32-5

The answer is 17

Answer:

The Answer is C.

Step-by-step explanation:

There is only one number before the decimal point, 6. 6 ones, so we already cross out A and D as incorrect. Now we have B and C. There is only two numbers after the decimal point. The first number after the point is in the tenths place. So, B is the correct answer.

Make me brainlyest if correct, you're welcome!
