Answer:

Step-by-step explanation:
Let the time flown by the flying carpet be  . Then, we have that
. Then, we have that  .
.
We multiply both sides of the equation by  to get
 to get  .
.
We subtract  from both sides to get
 from both sides to get  .
.
We divide both sides of the equation by  .
.
We know that the speed of the flying carpet in still wind is the average of the rates of the speed of the flying carpet with the wind and against the wind.
The speed with wind is  mph.
mph.
The speed against wind is  mph.
mph.
The speed in still wind is  .
.
Therefore, the answer is  and we're done!
 and we're done!
 
        
             
        
        
        
Answer:
75%
Step-by-step explanation:
we know that 60% of x is 120. we can rewrite this to .6x = 120, to get x we divide both sides by .6, so x = 200. now 120 + 30 = 150. then we divide 150 out of 200 which is .75 it 75%

Answer:
   2x² +5x -12 = 0
Step-by-step explanation:
When p and q are roots of a quadratic, its factored form can be written as ...
   (x -p)(x -q) = 0
Here, the roots are given as -4 and 3/2, so the factored form would be ...
   (x -(-4))(x -(3/2) = 0
Multiplying by 2 gives us ...
   (x +4)(2x -3) = 0
Expanding the product, we find the desired quadratic is ...
   2x² +5x -12 = 0
