12/36 = x/100
Then cross multiply 
1200 = 36x
Divide by 36
x = 33.33
Can’t sell 0.33 of an appliance, so your answer is 33.
        
             
        
        
        
Answer:
The answer is x=1
Step-by-step explanation:
-4(3x+6)+6=-30
-12x-24+6=-30
-12x-18=-30
-12x-18+18=-30+18
-12x=-12
-12x/-12=-12/-12
x=1
 
        
             
        
        
        
2x^2+7x-5+(-8x^2-3x+5)=-6x^2+4x.
        
             
        
        
        
Answer:
Here's how I would do it.  
Step-by-step explanation:
If two triangles are similar, corresponding sides are in the same ratio.
We know the measures of b and a, so we can calculate the ratio b/a.
d and b are in the same ratio, so

We know the measures of c, b, and a, so we can calculate the value of d.
 
        
             
        
        
        
Answer:

Rounded to the nearest hundredths: 11.69.
Step-by-step explanation:
I would use the Pythagorean theorem for this problem.
The difference between the highest point and the lowest point of AD is 9.8-7.2 = 2.6, so that would be the height of the triangle. The length/base of the triangle would be 11.4.
Now, just solve using Pythagorean's theorem:

Rounded to the nearest hundredths: 11.69.
I hope this helped you.
