Answer:
-83
Step-by-step explanation:
x+(x+1)=number 
x+(x+1)=-165
2x+1=-165
-1         -1
2x=-166
/2     /2
x=-83
We can check our work by adding -83+-82=-165 because -83 would be the smaller number. 
-83.
 
        
             
        
        
        
Answer: $24000
Step-by-step explanation:
Depreciation for 2018 = ($74,000 - $18000) / 7
= $56000/7
= $8000
Depreciation for 2019 = ($74,000 - $18000) / 7
= $56000/7
= $8000
Depreciation up to 2019 = $8000 + $8000 = $16000
Book value at end of 2019 = $74000 - $16000 = $58000
Revised residual value = $10,000
Number of remaining years = 4-2 = 2 years
Depreciation expensed for 2020 will be:
= ($58000 - $10,000) / 2
= $48000/2
= $24000

Answer:
- c = -4.5
- z = 20
- x = -12
- a = -4/7
Step-by-step explanation:
A way to do this that will always work is ...
- eliminate parenthses and collect terms
- subtract any constants from the left side
- subtract any variable terms from the right side
- divide by the coefficient of the variable
1. 
- 8c -11 -6c = -2
- 2c -11 = -2
- 2c = 9
- c = 4.5
2.
- 3z +4 -2z -9 = 15
- z -5 = 15
- z = 20
3.
- 12 -4x +18 = 36 +4x +18 -6x
- 30 -4x = 54 -2x
- -4x = 24 -2x
- -2x = 24
- x = -12
4. 
- 36a -9a -5 = 6a -17
- 27a -5 = 6a -17
- 27a = 6a -12
- 21a = -12
- a = -12/21 = -4/7
 
        
             
        
        
        
Step-by-step explanation:
step 1. 12x - 15 - 12x = 7x + 20
step 2. 12x - 12x - 15 = 7x + 20 (grouping of terms)
step 3. -15 = 7x + 20 (adding like terms)
step 4. -35 = 7x (subtract 20 from both sides)
step 5. this step is incorrect.
step 6. -5 = x ( divide both sides by 7)
step 7. x = -5 (put the variable first).
