Step-by-step explanation:
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
This would be much, much, much easier if you told us
what numbers you do have on each side of the scale now.
The idea (probably) is that the scale is balanced when
the numbers add up to the same amount on both sides.
So you need to put some numbers in the blanks that will either
add more to the side that has less, or subtract some from the side
that has more, to make both sides equal.
