Answer:
N = -5
Step-by-step explanation:
Move the decimal point right until it is right after the first significant figure.
N = 5
But wait! It's a decimal so it has to be negative.
N = -5
 
        
                    
             
        
        
        
Add 35 to 140 and then subtract 80 equals $95 
35 +140=170 -80
$95

Answer:
Step-by-step explanation:
The conjugate is found by changing the sign of the square root term.‡ (For this purpose, i = √-1.)
a) the sign of 3i is changed: 2 + 3i
b) the sign of sqrt(-5) is changed: 8 -sqrt(-5) = 8 -i√5
c) the sign of 2i is changed: 7 +2i
d) the sign of sqrt(7) is changed: 4 +√7
_____
‡ Actually, the conjugate of a binomial is formed by changing the sign <em>between</em> terms. The purpose is to allow the product of the binomial and its conjugate to be the difference of squares.
Conventionally, the conjugate of a complex number is the value with the sign of the imaginary part reversed. That is why (-2i+7)* = 7+2i.
