Answer:
 1. x= -56.25
Expand 
19.5-6.5x+36=201-4.5x-33
Simplify 
-6.5x+55.5=201-4.5x-33
Simplify again 
6.5x+55.5=-4.5x+168
Add 6.5 to both sides
55.5=-4.5x+168+6.5x
Simplify 
55.5=2x+168
Subtract 
55.5-168=2x
Simplify 
112.5=2x
Divide both sides by 2
−112.5÷2 = x
Simplfy 
x = -56.25
2. x > -7 ÷ 4
Or
Decimal Form: -1.75
Remove parentheses 
12x>4x+5−19
Simplify 
12x>4x-14
Subtract 
12x-4x>-14
Simplify 
8x>-14
Divide both sides by 8
x > -14 ÷ 8
Simplify 
x > -7 ÷ 4
Or
Decimal Form: -1.75
3. Answer: Step 2 has an error
Step-by-step explanation:
Given equation,
2(10 - 13x) = -34x + 60
By distributive property,
20 - 26x = -34x + 60
Now, we need to isolate x on the left side of the equation,
For this we need to eliminate constant term from the left side,
20 will be eliminated by subtracting 20 from both sides ( subtraction property of equality )
I.e. Step 2 has an error,
We need to use subtraction property of equality instead of using addition property of Equality,
Note : The correct steps would be,
Step 2 : 20 - 26x = -34x + 60 ( Subtraction property of equality )
Step 3 : 8x = 40  ( addition property of Equality )
Step 4 :  x = 5  (  Division Property of Equality )
Hope this helps!!! Good luck!!! ;)
 
        
             
        
        
        
Find the perpendicular line then find the intersection then find the point
perpendicular lines have slopes that are perpendicular
the slopes multiply bo -1
y=mx+b
m=slope
y=2x-3
2 is slope
2 times what=-1
what=-1/2
the equation is
y-3=-1/2(x-8) or
y=(-1/2)x+7
find intersection
at (4,5)
distance bwetweeen (8,3) and (4,5)

D=2√5
distance= 2√5
 
        
        
        
I believe you would solve for X like: 3x-10=2x-10.
        
             
        
        
        
28. 5/7(x)=20
X=28
Hope this helps! :)
