Answer:
3/24 = 7/x
c = $56
Step-by-step explanation:
A percent proportion is just basically a ratio, I could also write this as 3:24 = 7:x, it really doesn't matter. What does matter is that this is considered a percent proportion. Now, to solve a percent proportion, we have this formula.
a/b = c/d
Say b is the unknown value, we would do (a*d)/c, say a was the unknown value, we would do (b*c)/d, Basically, A and D are linked together and B and C are linked together so you take the two values that are linked together first, multiply them together, and divide by the pair that has a partner that is unknown.

Answer:
The equation of the plane is represented by 
.
Step-by-step explanation:
Algebraically speaking, a plane can be represented by following vectorial product:
(1)
Where:
, 
, 
- Plane coeffcients.
, 
, 
- Coordinates.
We need three distinct points to determine all coefficients. If we know that 
, 
and 
, the system of equations to be solved is:
(1)
(2)
(3)
The solution of this system is 
, 
, 
.
Hence, the equation of the plane is represented by .
