I'm just gonna assume that 6/3 and 1/2 are fractions.
First you have to find common denominators for the fractions to be added.
The first common denominator divisible by both the denominators is 6.
So 2x3=6 and 1x3=3 
and 3x2+6 and 6x2+12
so that would be 12/6 + 3/6 
Then you would proceed to add both of the numerators together which are 12 and 3. 
To get a total of 15/6. You can also simplify that into a mixed number 2 1/2.
 
        
             
        
        
        
Answer: A, n=o+3
Step-by-step explanation:
Nathan (n) is 3 years older than Olivia (o) so Nathan's age would equal Olivia's age plus 3 years.
Hope this helps :)
 
        
                    
             
        
        
        
Answer:
option (a) $6,240
Step-by-step explanation:
Given:
Purchasing cost of the equipment = $82,000
Estimated life = 5 years
Salvage value = $4,000
Revised expected life = 8 years
Now, 
Depreciation per year =  
therefore, 
The accumulated Depreciation at the beginning of year 4 
= Annual depreciation × years passed
= 15,600 × 3 
= $46,800
Thus,
The book value at the beginning of year 4 
= Purchasing cost - Depreciation 
= $82,000 - $46,800 
= $35,200
Now,
The remaining life = Revised estimated life - Years passed 
= 8 - 3 
= 5 years
therefore,
Depreciation expense = 
=  
= $6,240
Hence, 
The correct answer is option (a) $6,240
 
        
             
        
        
        
Answer:
m = j + 10
m + 3 = 3x
Step-by-step explanation:
 
        
             
        
        
        
X - y = -5
-y = -x - 5
y = x + 5...slope here is 1. A perpendicular line will have a negative reciprocal slope. All that means is flip ur slope and change the sign. So our perpendicular line will have a slope of -1.
y = mx + b
slope(m) = -1
(4,7)...x = 4 and y = 7
now we sub and find b, the y int
7 = -1(4) + b
7 = -4 + b
7 + 4 = b
11 = b
so ur perpendicular equation is : y = -x + 11 <==
